Quick Take

Pre-match view

Context last updated 27 Sep 2026, 14:35 · Europe/Bucharest

Chan owns the deeper hard-court record but keeps losing first sets — five of his six most recent completed matches — so this qualifying opener in Columbus could stretch.

Chan is the likelier winner in a low-confidence read. Of the two set-total prices reviewed, three sets or more at 2.9 is the one that offers anything; under 2.5 sets at 1.33 asks too much.

Context

Chan's slow starts have been the most consistent feature of a hard-court run that otherwise includes wins over higher-ranked opponents.
Losing the opening set as often as this puts Chan behind early and gives Petak a clear way into the first round of qualifying. The counterweight is that Chan's second sets on the same surface sit at 6-8, and he still won one of those six matches after dropping the opener, against Hugo Gaston on 1 August, so an early setback has not been terminal.
- First sets across 14 completed hard-court matches, 11 June to 19 August 2026: 4 wins, 10 losses
- Average 10.1 games per first set, with three tiebreaks in 14
- Dropped the opening set in five of his six most recent completed matches, 21 July to 19 August 2026
That is far too little to judge Petak's hard-court game on, so he arrives at this qualifying match with his level on the surface largely unknown. The four hard-court matches tracked for him this year, a 2-2 split, broaden the picture only slightly, and his more recent completed matches were played on clay, which makes the surface switch the open question rather than a settled strength or weakness.
- Hard-court set detail covers two completed matches, 23 and 25 February 2026, split 1-1
- Those two matches averaged 20.5 total games, with one tiebreak
- Four hard-court matches tracked for Petak this year, 2-2; the set-level record notes one retired match excluded
Chan, 21, was called into Canada's squad for the qualifier after Gabriel Diallo withdrew with a leg injury, and his only appearance of the tie was that doubles match alongside Félix Auger-Aliassime. The debut fixes his current standing at senior international level eight days before this fixture, but it was a straight-set doubles loss and carries no read on his singles form. Herbert and Bonzi took the opening set on a tiebreak before closing 7-6(4), 6-3.
- Named as a first-time Davis Cup nominee for Canada
- Partnered Félix Auger-Aliassime in the doubles in Quebec City
- Lost 7-6(4) 6-3 to Pierre-Hugues Herbert and Benjamin Bonzi
- Canada won the qualifying tie 3-1

Petak is a Czech player competing in the US college system for Ohio State, which listed him for both singles and doubles during its 21 and qualifying rounds. That confirms he was match-active in two events in the week before this fixture, although the entry itself is routine college scheduling rather than a specific advantage. It also places his current competitive environment in the United States, where this Columbus event is staged.
- Listed at No. 96 in singles in Ohio State's order of play
- Partnered Palavestra at No. 44 in doubles
- Listed for both singles and doubles again
