American bounces back to reach quarter-finals

Andy Roddick came from a set down to overcome Denis Kudla in the second round of the SAP Open in San Jose. The former world number one, who is back from injury, dropped the opener on a tie-break before hitting back to win 6-7 (5/7) 7-6 (7/5) 6-4. Third seed Milos Raonic banged down 18 aces during his 6-2 7-6 (9/7) win over Tobias Kamke. Kamke had set point in the second-set breaker but could not force a decider. Raonic's title hopes were also boosted by the withdrawal of top seed Gael Monfils, his scheduled semi-final opponent, due to a knee injury. Rising star Ryan Harrison got through his first-round match but had to battle hard against Olivier Rochus for a 4-6 6-2 6-3 triumph. The teenager was 3-1 down in the final set, but used his serve to his advantage and turned things around with 27 aces. Sam Querrey lost his first-round fixture with Denis Istomin, taking the first set but then losing 5-7 6-3 7-5. Meanwhile, Matthew Ebden defeated Dudi Sela 6-7 (7/9) 6-2 7-6 (7/1) and fifth seed Julien Benneteau saw off Ryan Sweeting 7-6 (7/3) 7-6 (7/5).
