3-Set Frequency 27.1% 32.9% +5.8pp (FAA)
Avg Games (Recent) 25.2 25.5 +0.3 (FAA)

Summary: Significant quality gap exists between these players. Auger-Aliassime holds a 457-point Elo advantage (1858 vs 1401), ranking 29th compared to Medjedovic’s 113th position. FAA has played 73 matches over the past 52 weeks with a 48-25 record, while Medjedovic has played 48 matches at 25-23. Both players show stable form trends, though FAA’s dominance ratio (1.18) suggests tighter matches than Medjedovic (1.21), indicating both experience similar competitive intensity despite the ranking difference.

Totals Impact: Quality gap suggests potential for more one-sided sets, which could reduce total games. However, both players’ three-set rates (Medjedovic 27.1%, FAA 32.9%) are moderate, suggesting matches don’t typically extend to maximum length. Average total games are nearly identical (25.2 vs 25.5), but this reflects Medjedovic’s lower-level competition.

Spread Impact: The 457 Elo point gap translates to approximately 80% win probability for FAA, suggesting a clear favorite. Medjedovic’s game win percentage (50.6%) achieved against weaker opponents will likely decline significantly against top-30 opposition.


Hold & Break Comparison

Metric Medjedovic Auger-Aliassime Edge
Hold % 79.0% 82.4% FAA (+3.4pp)
Break % 23.2% 23.6% FAA (+0.4pp)
Breaks/Match 3.94 3.86 Even
Avg Total Games 25.2 25.5 +0.3 (FAA)
Game Win % 50.6% 51.9% FAA (+1.3pp)
TB Record 9-7 (56.2%) 10-7 (58.8%) FAA (+2.6pp)

Summary: Auger-Aliassime holds a meaningful service advantage (+3.4%) but return games are nearly identical. Both players average approximately 3.9 breaks per match. The primary differentiator is FAA’s superior hold percentage, which should translate to more service game wins. Medjedovic’s 79% hold rate is vulnerable against quality opposition.

Totals Impact: The 3.4% hold advantage for FAA is significant but not extreme. With approximately 22-24 service games per match, this translates to roughly 0.7-0.8 additional holds for FAA. Similar break rates suggest even distribution of break opportunities. This points toward a moderate total around 22-24 games.

Spread Impact: FAA’s superior hold rate should produce a positive game margin. The combination of better serving and equivalent returning creates asymmetric advantage. Expect FAA to win service games more reliably while competing evenly on return games, producing a spread in the -3.5 to -4.5 game range.

Set Closure Patterns

Metric Medjedovic Auger-Aliassime Implication
Consolidation 79.2% 80.5% FAA holds after breaks slightly better
Breakback Rate 22.2% 22.6% Even fighting spirit
Serving for Set 79.3% 90.8% FAA closes sets much more efficiently (+11.5pp)
Serving for Match 73.7% 97.0% FAA closes matches decisively (+23.3pp)

Summary: Medjedovic shows stronger break point conversion (+4.9%) but FAA saves break points at a higher rate (+4.2%). The key differential is FAA’s superior BP save rate, which complements his already-higher hold percentage. FAA demonstrates superior clutch performance in match-defining moments, particularly when serving for sets (90.8% vs 79.3%) and matches (97.0% vs 73.7%).

Totals Impact: FAA’s higher BP save rate (68.1% vs 63.9%) reduces break frequency, keeping sets closer to 6-4/6-3 rather than 6-2/6-1. This moderately pushes totals upward. However, FAA’s exceptional closing ability (90.8% serving for set, 97.0% serving for match) limits three-set probability.

Tiebreak Probability: Both players have similar TB win rates (56.2% vs 58.8%), suggesting competitive tiebreaks when they occur. Combined with strong hold rates (79% and 82.4%), tiebreak probability is moderate to moderately-high. Estimate P(At Least 1 TB) = 42%, as one competitive set is likely but not guaranteed.

Rationale: Model projects 23.8 expected total games with 64% probability of exceeding 22.5, creating 13.6 pp edge over market’s no-vig 50.4% implied probability. The 3.4pp hold advantage for FAA combined with Medjedovic’s competitive 79% hold rate creates moderate tiebreak potential (42%), which pushes the total upward. Even in the most likely straight sets scenario (6-3, 6-4 or 6-4, 6-4), the total reaches 23-24 games. Three-set scenarios (32% probability) add significant upside tail risk with 27-29 game outcomes.

Market Game Handicap
Selection Auger-Aliassime -3.5
Target Price 1.96 or better
Edge 21.4 pp
Confidence HIGH
Stake 2.0 units

Rationale: Model projects FAA winning by 4.2 games (95% CI: 2.1-6.8), with 72% probability of covering -3.5 spread vs market’s no-vig 50.6%. The +457 Elo gap, combined with FAA’s superior hold rate (+3.4pp) and exceptional set closure efficiency (90.8% serving for set vs 79.3%), creates strong margin advantage. Six directional indicators converge on FAA covering: hold differential, Elo gap, Elo-adjusted game win %, quality of opposition, set closure patterns, and match-finishing ability (97.0% serving for match). The -3.5 line sits comfortably within the 95% CI and aligns with typical straight sets outcomes (6-3, 6-4 = 4-game margin).

Pass Conditions


Confidence & Risk

Confidence Assessment

Market Edge Confidence Key Factors
Totals 13.6pp HIGH Model 64% vs Market 50.4%, strong hold rates create TB potential, 95% CI well-calibrated to empirical averages
Spread 21.4pp HIGH Model 72% vs Market 50.6%, 6/6 directional indicators converge, +457 Elo gap decisive

Confidence Rationale: Both markets earn HIGH confidence due to edges exceeding 5% threshold (13.6pp and 21.4pp respectively), excellent data quality from 48 and 73 match samples, and strong model-empirical alignment. The 457-point Elo gap provides decisive quality differential that supports both the total games expectation (FAA’s efficiency limits variance) and the spread (FAA’s superiority drives margin). Form trends are stable for both players, eliminating recent volatility concerns. Clutch statistics favor FAA in critical moments (90.8% serve-for-set, 97.0% serve-for-match), further supporting high confidence in the spread coverage.
