A spot in the next round is at stake on Saturday, when Damir Dzumhur goes up against Maks Kasnikowski in the Olbia semifinal. Maks Kasnikowski is rolling — 3 straight wins, 6 of 10 in recent play. Damir Dzumhur has won 3 in a row and 6 of the last 10 overall.

The serve is where this match separates: Kasnikowski has been winning 68.1% of first-serve points to Dzumhur's 64.9%, and on hard that gap compounds fast. This one is close to a coin flip, and the lean toward Kasnikowski is exactly that — a lean.
