NEW YORK — The latest on the U.S. Open (all times local):
3:45 p.m.
For the second straight day, a professional tennis player was serving at the U.S. Open by just casually swinging the racket overhead. After Vitalia Diatchenko was forced to eschew the jump serve against Serena Williams on Monday night because of a foot injury, Australian teen Thanasi Kokkinakis found himself in the same position because of cramping on a steamy Tuesday afternoon.
In his U.S. Open debut, the 19-year-old Kokkinakis was in position to pull off an upset, leading 12th-seeded Richard Gasquet two sets to one, when his legs started to cramp in the fourth.
