SAN JOSE, Calif. (AP) -- Ryan Harrison has won his second-round match at the SAP Open, beating eighth-seeded Olivier Rochus of Belgium 4-6, 6-2, 6-3.
The 19-year-old American rallied past Rochus from 3-1 down in the third set to win the final five games. Harrison overpowered Rochus 27 aces to none, riding the momentum from last weekend's Davis Cup victory over Switzerland.
Day 3 of the tournament had a schedule packed with former and future promising Americans.
And following recent history, not all delivered.
Sam Querrey lost his second-round match against Russia's Denis Istomin 5-7, 6-3, 7-5. Andy Roddick was scheduled to face fellow American Denis Kudla later Wednesday night in his first match since retiring in the second round of the Australian Open with a right hamstring injury.
