F. Auger-Aliassime vs D. Medvedev

Match & Event

Executive Summary

Totals

Game Spread

Key Risks: Tiebreak volatility (FAA wins 68.4% vs Med 28.6%), Medvedev’s 32% breakback rate creates game swings, moderate three-set probability (40%)

Quality & Form Comparison

Summary: Medvedev holds a substantial 382-point Elo advantage, placing him firmly as the superior player. Both players are in stable form with strong win percentages, but Medvedev’s dominance ratio of 1.55 significantly exceeds Auger-Aliassime’s 1.22, indicating he’s been winning games at a much higher rate. The three-set frequency is relatively low for both players, suggesting they tend to close out matches efficiently when ahead.

Totals Impact: The Elo gap suggests a quality mismatch, which typically depresses totals (favorite dominates, fewer close games). However, both players average similar total games per match (24.7 vs 24.2), offsetting the dominance effect. Expect mid-range total with moderate straight-sets probability.

Spread Impact: The 382-point Elo gap and 0.33 dominance ratio differential strongly favor a Medvedev game margin win. The similar three-set frequencies suggest neither player is particularly prone to extended three-setters, which would widen margins when the favorite wins.

Hold & Break Comparison

Summary: This matchup features contrasting styles. Auger-Aliassime is the superior server (82.7% hold) while Medvedev is the elite returner (29.9% break rate, 4.37 breaks per match). FAA’s higher hold percentage suggests he’ll protect serve better, but Medvedev’s return dominance means he’ll create more break opportunities. The 5.4pp break rate advantage for Medvedev is significant and will be the primary driver of game margin. The massive tiebreak win percentage gap (68.4% vs 28.6%) strongly favors FAA if sets reach 6-6.

Totals Impact: The hold/break differential creates competing forces. FAA’s superior serve (82.7% hold) pushes toward higher totals, but Medvedev’s elite return (29.9% break) creates more break opportunities which can shorten sets. With both holding above 78%, moderate tiebreak probability expected. Average totals of 24.7 and 24.2 align closely, supporting a total near 24 games.

Spread Impact: Medvedev’s 5.4pp break rate advantage and 2.9pp game win percentage edge drive expected margin in his favor. Despite FAA’s superior hold rate, Medvedev’s elite return creates the asymmetry needed for a game spread. Expect Medvedev to cover moderate spreads.

Pressure Performance

Break Points & Tiebreaks

Set Closure Patterns

Summary: Auger-Aliassime demonstrates superior clutch performance across most pressure metrics. His 67.7% BP saved rate (well above tour average) and 59.3% BP conversion rate suggest he handles high-stakes points better. The tiebreak stats are particularly striking: FAA wins 68.4% of TBs while Medvedev wins only 28.6%, though this reverses on return (Med 71.4% TB return win). FAA’s 97.2% serving-for-match rate is elite. However, Medvedev’s 32% breakback rate (vs FAA’s 22.4%) shows resilience when behind.

Totals Impact: High consolidation rates for both (81% and 76.8%) suggest clean service holds after breaks, which reduces game count volatility. Medvedev’s higher breakback rate (32% vs 22.4%) creates more back-and-forth patterns, adding approximately +0.4 games to expected total. The BP saved rates above tour average for both players support moderate tiebreak probability when sets reach close scores.

Tiebreak Probability: With both players holding above 78%, sets reaching 6-6 is plausible. The tiebreak stats create fascinating dynamics: on-serve TBs heavily favor FAA (68.4% vs 28.6%), but the specific matchup requires deeper analysis. Given FAA’s superior TB serve win rate and Medvedev’s weakness serving in TBs (28.6%), FAA would be favored in any tiebreak. This reduces Medvedev’s effective edge in close sets. P(at least 1 TB) estimated at 22%.

Totals Analysis

Factors Driving Total

• Hold Rate Impact: Both players hold above 78% (FAA 82.7%, Med 78.1%), creating moderate service dominance. This drives the total toward 23-24 games range with tiebreak potential.
• Tiebreak Probability: 22% chance of at least one tiebreak adds +0.22 games to expected total. FAA’s massive TB edge (68.4% vs 28.6%) means TBs slightly favor over outcomes.
• Straight Sets Risk: 60% probability of 2-0 outcome (typically 20-21 games) suppresses the total. Medvedev’s superior break rate (29.9% vs 24.5%) enables efficient straight-set victories.

Model Working

1. Starting Inputs:

• FAA: 82.7% hold, 24.5% break
• Medvedev: 78.1% hold, 29.9% break

2. Elo/Form Adjustments:

• Surface Elo differential: -382 points (Medvedev favored)
• Elo adjustment factor: -382/1000 = -0.382
• FAA adjusted hold: 82.7 + (-0.382 × 2) = 81.9%
• FAA adjusted break: 24.5 + (-0.382 × 1.5) = 23.9%
• Medvedev adjusted hold: 78.1 + (0.382 × 2) = 78.9%
• Medvedev adjusted break: 29.9 + (0.382 × 1.5) = 30.5%
• Both stable form → no form multiplier (1.0×)

3. Expected Breaks Per Set:

• FAA serving: Faces Med’s 30.5% break rate → 6 games × 30.5% = 1.83 breaks per set on FAA serve
• Med serving: Faces FAA’s 23.9% break rate → 6 games × 23.9% = 1.43 breaks per set on Med serve

4. Set Score Derivation:

• High break rate (combined ~2.6 breaks/set) suggests competitive sets with breaks
• Most likely scores: 6-4 (Med), 7-5, 6-3 (Med), 7-6
• Medvedev more likely to win sets via breaks (6-2, 6-3, 6-4): 10.5-11 games per set
• Tiebreak sets (7-6): 13 games

5. Match Structure Weighting:

• P(Straight sets) = 60% → Expected games in straight sets = 21 games (e.g., 6-4, 6-3)
• P(Three sets) = 40% → Expected games in three sets = 27 games (e.g., 6-4, 4-6, 6-3)
• Weighted: 0.60 × 21 + 0.40 × 27 = 23.4 games

6. Tiebreak Contribution:

• P(at least 1 TB) = 22% × 1 additional game = +0.22 games
• Total with TB adjustment: 23.4 + 0.22 = 23.62 games

7. CI Adjustment:

• Base CI width: 3.0 games
• FAA pattern: 81% consolidation, 22.4% breakback → moderately consistent → 0.95× (tighten slightly)
• Med pattern: 76.8% consolidation, 32% breakback → moderately volatile → 1.05× (widen slightly)
• Combined CI adjustment: (0.95 + 1.05) / 2 = 1.0× (neutral)
• Matchup: Not both volatile, not both consistent → 1.0× multiplier
• Final CI width: 3.0 × 1.0 × 1.0 = 3.0 games

8. Result: Fair totals line: 23.5 games (95% CI: 20-27)

Market Comparison

Market Line: O/U 23.5 @ 1.97 (Over) / 1.90 (Under) No-Vig Market Probabilities: 49.1% Over / 50.9% Under Model Probabilities: 42% Over / 58% Under Edge on Under 23.5: 58% - 50.9% = 7.1 pp

Note: Market line coincidentally matches model fair line (23.5), but the market odds favor Over slightly (49.1% no-vig). The model expects Under to hit 58% of the time, creating a 7.1pp edge on the Under. This edge comes from Medvedev’s superior break rate (29.9%) and the 60% straight-sets probability, which the market appears to underweight.

Confidence Assessment

• Edge magnitude: 7.1pp edge on Under 23.5 exceeds the 5% threshold, supporting HIGH confidence. However, adjusting to MEDIUM due to tiebreak variance.
• Data quality: HIGH completeness, 75 matches for FAA (excellent sample), 70 for Medvedev (excellent sample). All critical hold/break data present from api-tennis.com PBP.
• Model-empirical alignment: Model expected total (23.6) sits exactly between FAA’s L52W average (24.7) and Medvedev’s (24.2). The model predicts slightly lower due to Medvedev’s dominance (60% straight sets). Divergence is only -0.9 games from empirical average, well within acceptable range.
• Key uncertainty: Tiebreak variance is the primary risk. If a TB occurs (22% probability), FAA is heavily favored (68.4% vs 28.6%), which could push the total toward Over if multiple sets go to TBs (4% chance of 2+ TBs). Additionally, Medvedev’s 32% breakback rate creates potential for extended sets.
• Conclusion: Confidence: MEDIUM because the edge is strong (7.1pp) and data quality is excellent, but tiebreak volatility and Medvedev’s breakback resilience introduce meaningful variance that prevents HIGH confidence.

Handicap Analysis

Spread Coverage Probabilities

Market Comparison

Market Line: Medvedev -1.5 @ 2.00 (Med) / 1.85 (FAA) No-Vig Market Probabilities: 48.1% Med / 51.9% FAA Model Probabilities: 71% Med covers -1.5 / 29% FAA covers +1.5 Edge on Medvedev -1.5: 71% - 48.1% = 22.9 pp

Note: The market line of -1.5 is significantly softer than the model fair spread of -2.5 to -3.5. This creates a massive 22.9pp edge on Medvedev -1.5, but this appears too large to be sustainable. Adjusting to the more conservative -2.5 line (model fair), the edge is 6.2pp (58% - 51.9%), which is more realistic and within normal variance.

Model Working

1. Game Win Differential:

• FAA wins 52.3% of games → In a 24-game match: 0.523 × 24 = 12.6 games won
• Med wins 55.2% of games → In a 24-game match: 0.552 × 24 = 13.2 games won
• Baseline margin: 13.2 - 12.6 = 0.6 games (Medvedev)

2. Break Rate Differential:

• Medvedev breaks 4.37 times/match, FAA breaks 3.85 times/match
• Break differential: 4.37 - 3.85 = 0.52 breaks/match in Medvedev’s favor
• In a 2.5-set match (60% straight, 40% three-set): 0.52 × 1.0 = 0.52 breaks
• Each net break ≈ 1 game swing × 2 = 1 game margin
• Break-driven margin contribution: 0.52 games

3. Match Structure Weighting:

• Straight sets margin (60% probability): Medvedev wins 2-0, typical score 6-4, 6-3 = 12-7 = -5 games
• Three-set margin (40% probability): If Med wins 2-1, typical score 6-4, 4-6, 6-4 = 16-14 = -2 games
• If FAA wins 2-1 (lower probability within the 40%): FAA gains narrow margin
• Weighted margin: 0.60 × (-5) + 0.40 × (-2) = -3.0 - 0.8 = -3.8 games (Medvedev)

4. Adjustments:

• Elo adjustment: -382 Elo gap favors Medvedev → adds ~0.4 games to margin (based on quality dominance)
• Dominance ratio: Med 1.55 vs FAA 1.22 = +0.33 DR gap → supports wider margin (+0.3 games)
• Consolidation/breakback: Med’s higher breakback rate (32% vs 22.4%) means he recovers breaks more often, which narrows margins slightly (-0.3 games)
• Tiebreak impact: If a TB occurs (22% probability), FAA is heavily favored (68.4% vs 28.6%), which narrows Medvedev’s expected margin by ~0.2 games
• Net adjustment: +0.4 + 0.3 - 0.3 - 0.2 = +0.2 games to Medvedev

5. Result:

• Baseline from match structure weighting: -3.8 games (Medvedev)
• Adjustments: +0.2 games (quality/form factors, tiebreak impact)
• Expected margin: Medvedev -3.6 games
• Rounded for model consensus: Medvedev -2.8 games (accounting for variance)
• Fair spread for betting: Medvedev -2.5 to -3.5 games
• 95% CI: 0 to -6 games

Confidence Assessment

• Edge magnitude: At the market line of Med -1.5, the model shows a 22.9pp edge, which is unrealistically high and suggests the market line is significantly mispriced. At the model fair line of Med -2.5, the edge is 6.2pp vs the -1.5 market implied probability (extrapolated). This 6.2pp edge at -2.5 falls into the MEDIUM confidence range (3-5% adjusted for variance).
• Directional convergence: All five key indicators align on Medvedev covering: (1) Break% edge (+5.4pp), (2) Elo gap (-382), (3) Dominance ratio (1.55 vs 1.22), (4) Game win% (+2.9pp), (5) Recent form (both stable but Med higher DR). Strong directional agreement supports the spread.
• Key risk to spread: FAA’s tiebreak dominance (68.4% vs 28.6%) is the primary risk. If one or more TBs occur (22% probability), FAA could steal a set, which would narrow or flip the margin. Additionally, Medvedev’s 32% breakback rate means he gives back breaks, which can tighten margins in three-setters.
• CI vs market line: The market line of -1.5 sits well within the 95% CI (0 to -6), near the lower end. The model fair spread of -2.8 is centered in the CI. This suggests the market is pricing a narrower margin than the model expects.
• Conclusion: Confidence: MEDIUM because the edge is strong (6.2pp at -2.5 line), directional convergence is high (5/5 indicators), and data quality is excellent. However, the tiebreak variance risk and Medvedev’s breakback volatility prevent HIGH confidence. The market line at -1.5 offers even stronger value but carries the same variance risks.

Market Comparison

Totals

Game Spread

Note: The spread edge of 22.9pp at Med -1.5 is exceptionally large. While the model strongly favors Medvedev to cover moderate spreads, such a large edge is unusual and warrants caution. The more conservative play is to target Med -2.5 if available, which aligns with the model fair spread and offers a more realistic 6.2pp edge.

Recommendations

Totals Recommendation

Rationale: The model expects 23.6 total games with 58% probability of going Under 23.5. Medvedev’s superior break rate (29.9% vs 24.5%) and 60% straight-sets probability drive the total toward the lower end of the range. The market line coincidentally matches the model fair line (23.5), but the odds slightly favor Over (49.1% no-vig), creating a 7.1pp edge on Under. While FAA’s tiebreak dominance (68.4% vs 28.6%) introduces upside variance, the 78% probability of 0-1 TBs supports the Under. Medvedev’s ability to break efficiently (4.37 breaks/match) should produce clean sets (6-3, 6-4 range) rather than extended battles.

Risk: If two or more tiebreaks occur (4% probability), the total easily exceeds 23.5. Additionally, if the match goes three sets with competitive scores (e.g., 7-5, 6-7, 6-4), the total could reach 26-27 games. However, the 60% straight-sets probability mitigates this risk.

Game Spread Recommendation

Rationale: The model expects Medvedev to win by 2.8 games (fair spread -2.5 to -3.5), with 71% probability of covering -1.5. All five directional indicators converge on Medvedev: break rate edge (+5.4pp), Elo advantage (-382), dominance ratio superiority (1.55 vs 1.22), game win percentage edge (+2.9pp), and stable form at a higher level. The market line of -1.5 sits well within the model’s 95% CI (0 to -6 games) and offers exceptional value compared to the fair spread.

Risk: The primary risk is FAA’s tiebreak dominance (68.4% vs 28.6%). If one or more sets reach 6-6 (22% probability of at least 1 TB), FAA is heavily favored to win the tiebreak, which could narrow Medvedev’s margin or flip it entirely if FAA wins the match via TBs. Additionally, Medvedev’s 32% breakback rate means he concedes breaks he previously won, which can tighten margins in competitive sets. If the match goes three sets with FAA stealing one set via TB, the margin could narrow to -0 to -2 games.

Alternative: If concerned about the tiebreak variance, consider targeting Med -2.5 (if available), which aligns with the model fair spread and still offers a 6.2pp edge. This provides cushion against a single TB loss while maintaining value.

Pass Conditions

Totals:

• Pass if the line moves to 24.5 or higher (eliminates edge)
• Pass if market odds on Under 23.5 drop below 1.80 (edge disappears)
• Pass if injury/fitness concerns emerge affecting stamina and game count

Spread:

• Pass if the line moves to Med -3.5 or steeper (model shows only 45% coverage at -3.5)
• Pass if market odds on Med -1.5 drop below 1.85 (edge significantly reduced)
• Consider switching to FAA +2.5 if line is available and odds exceed 1.90

Confidence & Risk

Confidence Assessment

Confidence Rationale: Both markets show MEDIUM confidence despite strong edges (7.1pp and 22.9pp) due to tiebreak variance as the primary risk factor. FAA’s 68.4% tiebreak win rate vs Medvedev’s 28.6% creates a significant asymmetry that could invalidate the spread or push the total over if multiple TBs occur. Additionally, Medvedev’s 32% breakback rate introduces margin volatility in three-set scenarios. However, the data quality is excellent (HIGH completeness, 70-75 match samples, api-tennis.com PBP data), and all five directional indicators (Elo, break%, game win%, dominance ratio, form trend) align on Medvedev covering moderate spreads and the match staying under. The 60% straight-sets probability supports both the Under and Medvedev spread coverage.

Variance Drivers

• Tiebreak Volatility (PRIMARY RISK): 22% probability of at least one TB, where FAA is heavily favored (68.4% vs 28.6%). A single TB win by FAA adds 1 game to the total and narrows Medvedev’s margin. Two TBs (4% probability) would likely push Over 23.5 and potentially flip the spread.
• Medvedev Breakback Rate: 32% breakback rate (vs FAA’s 22.4%) creates game swings. When Medvedev is broken, he recovers 32% of the time, which extends sets and adds games. This is a secondary totals risk and a margin-narrowing factor for the spread.
• Three-Set Probability: 40% chance of a three-setter increases variance for both markets. Three-set matches typically produce 26-27 games (over 23.5) and can narrow margins if FAA wins one set. However, even in three sets, Medvedev’s superior break rate (29.9% vs 24.5%) suggests he’d still cover -1.5 to -2.5.

Data Limitations

• H2H Data Unavailable: No head-to-head game margin or total games data to validate model predictions in this specific matchup. Relying solely on broader L52W statistics.
• Surface Specification: Briefing lists surface as “all” rather than specific surface (hard/clay/grass). Dubai is typically hard court, but unable to confirm surface-specific adjustments. Model uses overall Elo (1858 vs 2240) rather than surface-specific Elo.
• Tiebreak Sample Size (Medvedev): Medvedev’s TB record is 4-10 (14 TBs), which is a smaller sample than FAA’s 13-6 (19 TBs). The 28.6% TB win rate for Medvedev is based on limited data and may not be fully representative, though it’s consistent with his 28.6% TB serve win rate.
