Alexander Bublik and Learner Tien meet in the semifinal at Geneva on Friday. Alexander Bublik is 5-5 across recent matches. Learner Tien brings a 6-match winning streak into this one, 7-3 across the last ten.

The ledger favors Learner Tien, 2-0 across their 2 meetings with Alexander Bublik. On clay specifically it reads 2-0 Tien — worth more than the overall number this week.

The serve is where this match separates: Bublik has been winning 77.4% of first-serve points to Tien's 69.3%, and on clay that gap compounds fast. Bublik arrives with very little recovery time; Tien comes in off a compressed schedule. Bublik should have enough here, though Tien has the tools to make the scoreboard uncomfortable.
