National Bank Open: Jiri Lehecka vs Vit Kopriva

Platform comparison

Market context

Jiri Lehecka and Vit Kopriva are into the second round in Montreal, and the market’s 100% crowd read reflects a match-up that already looks heavily one-sided on paper. Lehecka is the higher-ranked player at ATP No. 12, while Kopriva is No. 71, and their only previous meeting ended 6-4, 6-1 to Lehecka on clay in Liberec in 2022.[6][11][15]

That is the main frame for reading the current price: Lehecka has the stronger hard-court profile and the cleaner top-level record, while Kopriva arrives as the underdog despite a solid opening win over Alexis Galarneau in Montreal.[5][8][10] Several previews pointed to Lehecka as a straight-sets favourite, but the market should still be read with the usual caveat that ATP second-round scheduling can be reshaped by late finishes, retirements, or court changes.[5][8][17]

For traders, the live catalysts are whether the match is started on Court 5 as scheduled, whether the draw order changes around other Montreal fixtures, and whether either player carries any fitness issue into the day.[2][6][7] Recent live listings show the contest on the order of play for 19:30 local time, while scoreboards had already moved into live coverage, which can quickly eliminate the 50-50 settlement risk if the winner is formally advanced.[1][2][4]
