A spot in the next round is at stake on Thursday, when Coco Gauff goes up against Elena Rybakina in the Toronto semifinal. Elena Rybakina brings a 3-match winning streak into this one, 6-4 across the last ten. Coco Gauff brings a 3-match winning streak into this one, 9-1 across the last ten.

Rybakina's 70.1% behind the first serve (against 66% for Gauff) means break chances should be scarce in one direction. Rybakina comes in off a compressed schedule. Expect resistance, but the match-level math tilts clearly toward Rybakina.
