═══ A. Hernandez (#1380, age 21) vs B. Tomic (#194, age 33) — Los Cabos, hard ═══
MODELS
ELO: A 26.3% / B 73.7% (heavily favours Tomic)
ML: A 42.3% / B 57.7% (near coin-flip)
Sim baseline: A 39.2% / B 60.8%
Market Betfair: A 35.2% (2.84) / B 65.4% (1.53) book: A 40.5% / B 64.9%
Models STRADDLE the market — ELO well above, ML/sim below. Classic no-consensus spot.
SIM INPUT VALIDATION (resimulate)
Baseline spw_a 0.581 / spw_b 0.597, holds 0.669 / 0.799. Sim gives A 39.2%.
But Hernandez's 50-match sample is dominated by M15/M25 CLAY wins over weak
fields (opp ELO 1500-flat, 1183, 1377) — his serve numbers are farmed on weak
clay, NOT hard-court quality. Off-surface + weak-field bias inflates the sim.
Re-run with justified shade spw_a 0.581 -> 0.55 (-0.031, within +/-0.05):
A win prob collapses to 24.4%, B 75.6% — CONVERGES on ELO (26.3%).
Conclusion: baseline sim/ML overstate Hernandez; ELO is the credible anchor.
Tomic is genuinely the clearly stronger player on hard court.
ELO vs RANKING SANITY
Tomic #194, ELO-favourite — agreement; ELO credible (real quality wins:
Lajal 1705, Johnson 1605, McCabe 1593, Blanch 1596 en route to Lincoln title).
Hernandez #1380 with ~25% ELO — agreement; genuinely a low-level developing
player. No farmed-rating distortion; ELO trustworthy both ways.
RECENT FORM (last 5)
Hernandez:
07-27 Los Cabos F W vs Magadan (1457) 6-3 7-6(tb) GRIND, weak opp
07-26 Los Cabos SF W vs Mejia (1579) 7-5 6-2 DOM, avg opp

07-07 Bogota clay L vs Hardt (1665) 6-7 6-4 2-6
06-30 Quito clay L vs La Serna (1588) lost 3 sets
Shape: shallow SHARPENING (2 hard-court wins vs weak/avg fields) on top of a
losing June/early-July clay stretch. Path: 2 matches deep at venue (match-
sharp). NOTE: won Los Cabos title today (07-27) -> mild let-down risk next out.
Tomic:
07-27 Los Cabos F L vs Boyer (1500) 0-0 (voided/incomplete record)
07-26 Los Cabos SF W vs Tobon (1390) 7-5 4-6 6-7 long 3-set GRIND vs weak
07-21 Bloomfield L vs Boyer (1595) 3-1 (incomplete)
07-19 Lincoln F W vs Lajal (1705) 4-6 7-6 7-6 GRIND, title, over Strong
07-18 Lincoln SF W vs Johnson (1605) 6-7 6-3 6-2 GRIND, over Strong
Shape/profile: strong recent hard-court results but a GRINDER — wins long tight
3-setters and tiebreaks even against players he beats. TITLE: Lincoln 8d ago.
Grinder margins are evidence AGAINST any -3.5 blowout cover.
FATIGUE
Tomic (age 33, >=30 -> harden a tier): 8 matches/14d, 3/7d, 23 sets, 948 court
minutes, back-to-back streak 3, just played Los Cabos SF (long 3-setter) + Final.
EXTREME spot (3rd+ consecutive match day, huge cumulative load, age 33 recovers
slowly). Genuine WIN disadvantage — offsets his class edge.
Hernandez (age 21): 2 matches/14d, 189 min, fresh. Big differential favouring A,
but per calibration a cumulative-minutes gap is CONTEXT, never a standalone edge,
and A is still overpriced on his true level.
NARRATIVE
Tomic let-down: won Lincoln Final 8d ago = WEAK; lost Los Cabos Final 0d = NOTE.
Surface transition: none — both on hard court recently.
DATA-QUALITY FLAG: both players show a "Los Cabos - Final 07-27" vs DIFFERENT
opponents and Tomic's record is 0-0 (voided). Impossible bracket -> feed
contradiction. Reason for extra caution, reinforces PASS.
ALT MARKETS (one coherent distribution)
A +3.5: baseline cover 56.2% vs eff 1.836 (54.5%) = +1.7% (below 5% bar);
on corrected/ELO-converged sim cover falls to ~39% -> NEGATIVE. Dead.
B -3.5: baseline cover 43.8% (negative). "Edge" only appears (~+10%) AFTER my
SPW shade -> manufactured, and B -3.5 is a HIGH-VARIANCE lay needing a
blowout that Tomic's grinder profile + extreme fatigue directly negate.
Totals 21.5: sim over 50.8% / under 49.2%, expected total 22.0 sits ON the line.
No edge either side after commission. Dead.
GATES
G1 edge-origin: FAIL — no robust pre-adjustment model-vs-market edge. A is
overpriced by every model (<=26% true vs 35% market) so any A edge would be
pure fatigue (definitional G1 fail). B's only supporting model is ELO; the
B -3.5 edge is manufactured entirely by my own input shade (baseline negative).
G2 consensus: FAIL — for B, ML+sim sit against the pick (call B overpriced),
only ELO favours it. For A, market + all models sit against. No side clears.
G3 fatal-risk: FAIL — any lay/-cover of Tomic is negated by his grinder profile
(tight 3-setters/tiebreaks) + extreme fatigue = wins close, not by 4+. Backing
B ML has its class edge eaten by the same extreme fatigue; backing A means
laying money on a player the models price ~10pts too short.
VERDICT: PASS. Tomic is the stronger player (ELO 73.7%, sim converges once
Hernandez's weak-field-farmed serve is corrected), so there is no value backing
the overpriced fresh underdog. But Tomic's extreme age-33 fatigue overhang
(948 min/14d, back-to-back 3) eats his class edge and makes laying him at 1.53 /
covering -3.5 a fade of his own grinder profile. Models straddle, alt edges
evaporate under scrutiny, and the bracket data is self-contradictory. No bet.
