Bautista Torres Juan and Tomas Barrios Vera meet in the round of 16 at Curitiba on Wednesday. Tomas Barrios Vera has won 2 of the last 10. Bautista Torres Juan comes in at 5 wins from the last ten.

Vera's 64.9% behind the first serve (against 60.7% for Juan) means break chances should be scarce in one direction. Juan comes in off a compressed schedule; Vera comes in off a compressed schedule. The edge belongs to Vera — real, but not the kind you take for granted at this level.
