RECENT FORM (last 5 each) Burruchaga: - 07-16 Umag QF W vs Ugo Carabelli (1822, Strong) 6-2 2-6 6-3 — routine 3-setter, dropped a set - 07-15 Umag R16 W vs Cobolli (1915, Elite) 6-2 6-4 — DOM vs Elite (standout result) - 07-14 Umag R32 W vs Cecchinato (1699, Strong) 6-1 6-4 — DOM - 07-07 Braunschweig L vs Schoenhaus (1630, Avg) 3-6 3-6 - 06-30 Wimbledon L vs De Minaur (1867, Elite) Pre-Umag form was poor (5 losses in 6 before this week). Hot week, cold month. Merida Aguilar: - 07-16 Umag QF W vs Droguet (1809, Strong) 6-1 6-3 — DOM - 07-15 Umag R16 W vs Etcheverry (1801, Strong) 7-5 6-4 — clean two-setter - 07-14 Umag R32 W vs Sesko (1440, Weak) 6-4 6-1 — DOM - 07-01 Wimbledon L vs Medvedev (1820, Strong) in 4 - 06-29 Wimbledon W vs Ugo Carabelli Deep clay pedigree: Perugia final 06-07, Rome challenger title 05-05. FATIGUE (14d) Burruchaga: 4 matches, 12 sets, ~430 min court time, back-to-back x2 Merida: 3 matches, 9 sets, ~295 min court time, back-to-back x2 Diff 135 min > 60 → Burruchaga clearly disadvantaged. All three of his Umag matches went the distance or near it; Merida has two quick DOM wins. NARRATIVE Let-down: none (Merida's last final Perugia 40d ago — stale). Venue: both 3-0 at Umag this week — neutral. Title recency: Merida — Rome challenger 73d ago (clay). VERDICT: PASS ELO likes Burruchaga but sim edge is only +3.5% (<5% bar) and the qualitative read runs AGAINST it: he carries 135 extra court minutes into a 4th straight match day while Merida arrives fresher off two dominant wins. The Cobolli scalp is real, but fatigue undercuts the model disagreement rather than validating it. No edge on Merida either at 1.72 (sim 51.6% vs 58.1% implied). No alt markets priced.
