WASHINGTON — Sloane Stephens, coming off a quarterfinal run at Wimbledon, crashed out Monday in the first round of the WTA and ATP Washington Open. The 20-year-old American, ranked 15th in the world and seeded second on the women's side of the $1.76 million hardcourt event, was ousted 7-5, 6-3 by Russia's Olga Puchkova. “There were some (shots) I really couldn't believe went that far out,” Stephens said. “The ball was flying everywhere. “I just couldn't find it. When you don't practice well it shows. I had a couple rough days, and it showed.” Stephens is already trying to tamp down US Open expectations after beating current world No. 1 Serena Williams on her way to the Australian Open semifinals, where she lost to then-No. 1 Victoria Azarenka. “If I lose in the first round, don't be upset,” she said. “It's going to be my first time there playing under so much pressure and everyone expecting me to do so well. Mardy Fish, who has missed most of the past year with heart problems, won his first ATP match since March, rallying to outlast Australian qualifier Matthew Ebden 2-6, 6-1, 6-3. Fish faces French 12th seed Julien Benneteau in the second round. Aussie qualifier Samuel Groth blasted 20 aces to beat American Denis Kudla 7-6 (7/2), 6-2 to book a second-round match against big-serving Canadian Milos Raonic while Aussie Marinko Matosevic ousted another struggling US veteran, James Blake, by 6-2, 7-6 (8/6). In other first-round matches, 2011 champion Radek Stepanek defeated American Steve Johnson 7-6 (3), 6-3. Somdev Devvarman, David Goffin and Paula Ormaechea also advanced. On the women's side, defending champion Magdalena Rybarikova rallied to beat American Christina McHale 2-6, 6-4, 6-2. The Slovakian seventh seed will face compatriot Jana Cepelova in the second round with a possible third-round date against German top seed Angelique Kerber. — Agencies
