Swiatek's serve did the quiet work: 39 of 54 first serves in, 72 percent, 29 first-serve points won, and a perfect record on the three break points she faced all match. One double fault in two sets, no aces required. She won 38 of her 54 service points; Li managed 31 of 58, on just 60 percent first serves, with two double faults and a 0-for-3 return card.
The semifinal belongs to Swiatek, and the return column explains why: 28 points won against the Li serve, 16 the other way. Five games, nine break points faced on serve, none created after the first set — the arithmetic of a one-sided night.
