A spot in the next round is at stake on Saturday, when Daniel Rincon goes up against Jan Choinski in the Braunschweig semifinal. Jan Choinski is rolling — 3 straight wins, 6 of 10 in recent play. Daniel Rincon brings a 3-match winning streak into this one, 7-3 across the last ten.

There is no history here: this is their first tour-level meeting.

The serve is where this match separates: Choinski has been winning 69.4% of first-serve points to Rincon's 66.4%, and on clay that gap compounds fast. Rincon comes in off a compressed schedule; Choinski comes in off a compressed schedule. This one is close to a coin flip, and the lean toward Choinski is exactly that — a lean.
