A spot in the next round is at stake on Thursday, when Rafael Jodar goes up against Valentin Vacherot in the Basel round of 16. Rafael Jodar has won 8 of the last 10. Valentin Vacherot comes in at 7 wins from the last ten.

On paper it's close: comparable ratings, comparable serve numbers, small margins everywhere. This one is close to a coin flip, and the lean toward Jodar is exactly that — a lean.
