Wong vs Altmaier Prediction 14 August 2026


🔊 Chak Lam Coleman Wong is having a strong hard-court stretch this season, with a semifinal at the ATP 250 in Los Cabos and a main draw appearance at the Masters in Cincinnati as his peak result. Notably, this is not his first appearance here: last year the Hong Kong representative reached the second round at the American 1000-level event. In this year's draw, he needs to get past Daniel Altmaier to match his best result on these courts. The German is a former top-50 player, but has never made it past the opening round in Cincinnati. Let's assess his chances of breaking that losing trend.
Head-to-Head
📊 The players have met once - Chak Lam Coleman Wong won 2:0. The match took place last year on the hard courts of Miami.

Daniel Altmaier Player Overview
Daniel Altmaier is going through an inconsistent stretch: only four wins in his last ten matches and frequent early exits at recent tournaments - in his last three events he has consistently gone out in the second round. His serve holds up well: he wins 81% of points on his own serve, but his overall set-winning rate is just 45%. There are also problems on the return, where he converts just 31% of break points, which reduces his chances of turning a match around against an opponent in better form.
