MATCH: M. Sherif (A) vs T. Korpatsch (B) - Hamburg (clay), semifinal stage Book: A 1.59 / B 2.36 | Betfair ML: A 1.64 / B 2.52 (executable: A implied 62.2% eff., B 41.8% eff.) Models: ELO A 66.6% | ML A 76.2% | Blend A 61.9% | value_pick A (+2.2% vs book) MODELS vs MARKET - All three models side with Sherif, same direction as the market. Blend 61.9% vs Betfair-effective 62.2% = no edge. ELO gives +4.4% (below 5% bar). Only the ML model (76.2%) shows a large gap. - ELO/ranking sanity: Sherif ELO-favourite but ranked 114 vs Korpatsch 87. Her rating run is built heavily on ITF-tier fields (Contrexeville, Brescia/Modena quals, Foggia) - partial farmed-rating flag. The two wins over Badosa (ELO 1858, Iasi final + Hamburg QF) are genuine, but both were grinds. ELO edge discounted. RECENT FORM (last 5 shown; all fetched matches used) Sherif - 13-match win streak, all clay: - 07-24 Hamburg QF W vs Badosa (1858): 7-6 6-7 6-4 - GRIND vs Elite - 07-23 Hamburg R16 W vs Jacquemot (1554): 6-2 6-3 - DOM vs Avg - 07-22 Hamburg R32 W vs Waltert (1743): 7-5 4-6 7-6 - GRIND vs Strong - 07-20 Iasi FINAL W vs Badosa (1853): 6-4 4-0 - title 5d ago - 07-18 Iasi SF W vs Oliynykova (1786): 6-3 6-1 - DOM vs Strong Pattern: vs Strong/Elite she wins in GRINDs (tiebreaks, 3-setters); DOMs come vs weaker fields. Korpatsch: - 07-24 Hamburg QF W vs Kalinina (1837): 6-3 1-6 6-1 - win vs near-Elite - 07-22 Hamburg R16 W vs Stusek (1512): 6-0 3-6 6-3 - 07-21 Hamburg R32 W vs Jimenez Kasintseva (1547): 3 sets - 07-08 Bastad R16 L vs Lepchenko (1575): 6-1 6-2 - blowout loss to Avg opponent - 07-07 Bastad R32 W vs Bajraliu (1401) Also carries other recent blowout losses (Gauff 6-2 6-1, Begu 6-1 6-4, Sierra 6-3 6-1). FATIGUE (precomputed) - Sherif: 11 matches/14d, 6 in 7d, 33 sets, 6 back-to-backs, 1180 court min, played 07-24. Age 30 - slow recovery, disadvantage HARDENED. Extreme load: three straight tournament runs (Contrexeville title, Iasi title, Hamburg SF). - Korpatsch: 3 matches/14d, 9 sets, 317 court min, played 07-24. Court-time gap ~860 min - Sherif heavily disadvantaged. NARRATIVE - Title recency Sherif: Iasi 5d ago (clay) + Contrexeville 13d ago - WEAK let-down window, but she has kept winning through it. - H2H: Korpatsch beat Sherif in the Rome final (May, clay) 6-3 5-7 7-6 - tight, recent, on-surface. - No surface transition either side (both on clay runs). MARKET SCAN (Step 4b) - Sherif ML at 1.64 BF: blend shows no edge; ELO edge 4.4% below the 5% bar; only the ML model clears it, but the fatal fatigue risk and farmed-ELO flag sit against backing her. - Korpatsch ML at 2.52 BF: NO model gives B more than the market's 39.7% (ELO 33.4%, ML 23.8%, blend 38.1%). Any edge here would be manufactured from fatigue - prohibited. - Handicap B +3.5 at 1.87: model cover prob is null (no anchor). Margin evidence mixed - H2H tight and Sherif grinds vs quality, BUT Korpatsch has multiple recent blowout losses (6-1 6-2 to Lepchenko two weeks ago) which negates a stay-close thesis; and fatigue may not carry a cover. - Total 20.5: model over 53.9% vs 52.1% implied at 1.92 = +1.8% - below bar. Under negative. GATES G1 edge-origin: FAIL - B side has zero numeric model-market edge (all models below market's 39.7%); A side blend/ELO below the 5% bar; only the outlier ML model clears it. G2 consensus: FAIL - for any B bet, market AND two of three models sit against; on-surface H2H (Rome final win) is the lone support, models still disagree. G3 fatal-risk: FAIL - backing Sherif: 1180 court min / 11 matches in 14d at age 30 directly negates; backing Korpatsch cover: her own recent blowout losses (Lepchenko 6-1 6-2) negate the stay-close thesis. VERDICT: PASS. Efficient spot - the market has already priced Sherif's fatigue down from what raw models say (Betfair 1.64 vs ML-model 76%), and there is no numeric edge on Korpatsch to pair with the fatigue story. Thin total edge (1.8%) and an unanchored handicap do not clear any bar.
