A spot in the next round is at stake on Wednesday, when Alex Barrena goes up against Jan Choinski in the Bonn round of 16. Jan Choinski is 7-3 across recent matches. Alex Barrena limps in on a 2-match losing skid, just 3 wins in 10.
The serve is where this match separates: Choinski has been winning 69.5% of first-serve points to Barrena's 63.7%, and on clay that gap compounds fast. Barrena comes in off a compressed schedule. Anything other than a Choinski win would rank among the bigger surprises of the week.
