F. Tiafoe vs J. Choinski — Wimbledon 1/32 (grass)
═══════════════════════════════════════════
MODELS
ELO : Tiafoe 76.4%
ML : Tiafoe 79.1%
Model : Tiafoe 72.6%
Market: Tiafoe 83.1% (1.14 / 5.60)
Value : bot flags B +10.5% edge (devig-derived), 2.5u
-> Models LESS bullish than market on a 1.14 favorite; the "edge" on the
dog is a devig artifact, not a qualitative signal.
FORM
TIAFOE (grass, hot): WON HALLE TITLE 21 Jun — beat Fritz (2011, Elite)
6-4 6-4 in the Final. En route bt Auger-Aliassime (1751, GRIND),
Shimabukuro (1743) 6-4 7-5, Cobolli (1732, GRIND), Altmaier DOM 6-1 6-3.
Wimbledon R1: bt Atmane (1480) in 4 (GRIND). Class + live grass form.
CHOINSKI (grass, softer field): Wimbledon R1 bt Kopriva (1583) 6-3 7-5 6-2.
WON EASTBOURNE TITLE 21 Jun (250-level, opp all <1700) but then lost
Eastbourne QF vs Bergs (1639) 3-6 3-6. Grass wins vs weak opponents.
FATIGUE
Tiafoe : 5 matches/14d, 512 court min, b2b 2, last 1 Jul
Choinski: 8 matches/14d, 992 court min, b2b 4, last 30 Jun
-> Court-time diff 480 min (>60) — HEAVY fatigue disadvantage on Choinski,
i.e. fatigue favors the FAVORITE, not the dog. No dog value here.
NARRATIVE
Let-down: Choinski won Eastbourne Final 11d ago then already lost a QF —
title bounce spent, no fresh let-down edge either direction.
Venue: neither has Wimbledon history in window.
TITLE (Tiafoe): Halle 11d ago (grass) — live grass form outweighs any
historical surface gap; Tiafoe is genuinely peaking on grass.
VERDICT — PASS
The only "edge" is a devig artifact on a heavy (1.14) favorite. The
qualitative read kills it: Tiafoe is the higher-class player, just won a
grass title beating an Elite (Fritz), and is far fresher. Choinski is
gassed (992 court min/14d) and his grass results came against weak fields.
Backing the dog at 5.6 has no real support. No side, no bet.
