Aryna Sabalenka and Jessica Pegula meet in the semifinal at US Open on Thursday. Aryna Sabalenka brings a 5-match winning streak into this one, 8-2 across the last ten. Jessica Pegula is rolling — 4 straight wins, 9 of 10 in recent play.

Hold strength tells the story — 67% versus 63.9% on first-serve points in Sabalenka's favor. The edge belongs to Sabalenka — real, but not the kind you take for granted at this level.
