NEW YORK — At 19, Jack Sock could be the next great hope for American men’s tennis.
At 30, Mardy Fish is already part of the old guard.
Both players won their second-round matches Thursday at the U.S. Open, keeping alive the hope that at least one American could make a deep run here.
Sock, who was born in Nebraska and lives in Kansas City, routed Italian Flavio Cipolla, 6-2, 6-2, 6-4 on Court 17, punctuating the match with an exaggerated fist pump.
Shortly thereafter, the No. 23-seeded Fish completed a comeback from two sets down to beat former world No. 3 Nikolay Davydenko of Russia, 4-6, 6-7 (4), 6-2, 6-1, 6-2 in Arthur Ashe Stadium. It was the 10th comeback from 0-2 down in this men’s tournament, a new record.
