Wednesday's Bonn round of 16 pits Alex Barrena against Jan Choinski on clay. Jan Choinski has won 7 of the last 10. Alex Barrena is searching for form, having lost 2 in a row (3 of the last 10).
Hold strength tells the story — 69.5% versus 63.7% on first-serve points in Choinski's favor. Barrena comes in off a compressed schedule. If Choinski plays anywhere close to a normal level, this ends in relatively comfortable fashion.
