TennisEdge's AI model finds no betting value in E. Jones vs M. Brengle (Vancouver on 2026-07-29) — the market is efficient, with E. Jones favoured at 1.45.
MATCH: E. Jones (18, no.147) vs M. Brengle (36, no.453) - Vancouver, hard, 1/8-finals
MODELS vs MARKET
ELO A 74.5pct | ML A 71.7pct | blended 68.3pct vs Betfair A 1.45 (impl ~69pct, comm-adj breakeven 70.1pct).
Full model/market consensus on the winner (Jones favourite). Blended model 68.3pct sits BELOW the
commission-adjusted breakeven of 70.1pct so A ML carries NEGATIVE edge at the executable price.
Only the outlier ELO (74.5pct) would price value, and Jones is an 18yo with thin/volatile ELO - not
a rating to lean on against ML+blended agreement.
RECENT FORM
Jones (A): W vs Zhao 6-3 4-6 6-4 (GRIND, Avg, Vancouver R1); L vs Akli 5-7 4-6; Wimbledon SF run;
recent hard title-run at W100 Gifu (Final). Shape STABLE - grinding 3-setters vs weak/avg, not
dominating. Match-sharp: 1 win at this venue.
Brengle (B): W vs Vagramov 6-4 4-6 6-2 (GRIND, Weak, Vancouver R1); veteran level-dropper whose ITF
W35/W50/W100 record is fattened by weak fields - stats inflated, edge discounted. Shape soft.
FATIGUE (Step 2 calibrated)
BOTH won a 3-set match yesterday (07-28) so each carries the -4.5pp 3-set-hangover haircut.
Age modulation: Jones 18 (recovers fast, softened ~-2pp); Brengle 36 (recovers slow, hardened ~-5.5pp).
Net: fatigue tilts SLIGHTLY toward Jones but only reinforces the existing favourite - context, not an
edge, cannot create one (G1).
MARGIN MARKETS
Sim handicap: A -3.5 covers 48.9pct (@1.82 edge -7.3pct); B +3.5 covers 51.1pct (@2.04 edge +0.8pct,
below bar). Totals 20.5: over 49.8pct (@1.97 neg), under 50.2pct (@1.94 neg). No margin edge.
GATES
G1 edge-origin: FAIL - no numeric model-vs-market gap survives at the executable price (A ML -1.8pct
on blended; best alt B+3.5 only +0.8pct). Any lean would rest on fatigue/ELO-outlier, not a real edge.
G2 consensus: stake-tier only - full model consensus WITH market, no independent evidence to bet.
G3 fatal-risk: n/a (no bet).
VERDICT: PASS. Textbook efficient market - three models agree with the exchange on the winner and every
priced market (ML, handicap, total) is at or below breakeven. Nothing to stake.
