HOW EACH FACTOR MATTERS
Level (Elo/ranking)▸ Lehecka●●●
Elo 2028 vs 1796 and rank #14 vs #109 back a 63% baseline vs 45% — a clear class gap favoring Lehecka.
Serve/return▸ Lehecka●●●
Lehecka's 70% serve overwhelms Wong's 33% return; Wong's 66% serve meets a stronger 34% return, net edge Lehecka.
Form▸ Lehecka●●
Lehecka's 6/10 includes wins over Tiafoe (Elo 2012) and Molcan (1942); Wong's 5/10 has no quality wins despite a 1-match streak.
Rest= Even
Lehecka's 21-day layoff (0 matches in 14 days) risks rust, while Wong's 4 matches in 14 days signal possible fatigue — effects roughly offset.
Value▸ Wong●●
Model gives Lehecka 76% vs market's 83% (odds 1.21), producing -7.8% EV — the price overstates his edge.
LEVEL AND CLASS

Lehecka's Elo rating of 2028 dwarfs Wong's 1796, a 232-point gap that typically corresponds to a large favorite in a single match, and his ranking of #14 versus #109 confirms a substantial class difference.

This is reinforced by the baseline point-winning rates: 63% for Lehecka against just 45% for Wong, an 18-point gap that suggests Lehecka simply wins more points on average across the board, not just on serve.

FORM AND MOMENTUM

Lehecka's last 10 matches (6-4) include notable wins over Tiafoe (Elo 2012) and Molcan (1942), showing he can beat legitimate top-100 opposition even while currently on a one-match losing streak.

Wong is 5-5 over his last 10 with a short one-match winning streak, but he has no quality wins listed, so despite similar overall records, the caliber of Lehecka's results tilts this factor in his favor.

SERVE-RETURN MATCHUP

Lehecka's 70% service-point win rate against Wong's 33% return rate points to a serve that should hold comfortably in this matchup.

In the reverse direction, Wong's own serve (66%) runs into a better return from Lehecka (34%), meaning Lehecka's return also outperforms Wong's return — a double edge in ball-striking exchanges.

REST AND SCHEDULE

Lehecka has been idle for 21 days with zero matches in the last two weeks, which the data flags explicitly as a rustiness risk after such a long gap.

Wong, by contrast, has played four matches in the past 14 days and comes in on just five days' rest — potentially sharper timing-wise, but also carrying more physical fatigue into a five-set format. These two schedule effects likely cancel each other out rather than clearly favoring either player.

VALUE READ

The model places Lehecka's win probability at 76%, below the market's implied 83% at odds of 1.21, yielding a -7.8% expected value on the favorite.

This does not mean Wong is likely to win — Lehecka remains the clear favorite on class, form, and serve/return numbers — but it does mean the current price does not offer value on him. Being the favorite and being a value bet are not the same thing here, and backing Lehecka at this price is a bet against the model's own math.
