Wednesday's Sion (Switzerland) round of 16 pits Benjamin Hassan against Sandro Kopp on clay. Benjamin Hassan comes in at 5 wins from the last ten. Sandro Kopp comes in at 4 wins from the last ten.

Hold strength tells the story — 70% versus 64.9% on first-serve points in Hassan's favor. Hassan arrives with very little recovery time; Kopp comes in off a compressed schedule. This one is close to a coin flip, and the lean toward Hassan is exactly that — a lean.
