A spot in the next round is at stake on Thursday, when Aryna Sabalenka goes up against Jessica Pegula in the US Open semifinal. Aryna Sabalenka is rolling — 5 straight wins, 8 of 10 in recent play. Jessica Pegula brings a 4-match winning streak into this one, 9-1 across the last ten.
Sabalenka's 67% behind the first serve (against 63.9% for Pegula) means break chances should be scarce in one direction. Sabalenka should have enough here, though Pegula has the tools to make the scoreboard uncomfortable.
