Andy Roddick refocused after losing his cool Tuesday to reach the third round of the Shanghai Masters with a 7-6 (7/3), 7-5 win as top American Mardy Fish crashed out to Australian teen Bernard Tomic. Tenth seed Roddick won a first set tie-break against Bulgaria’s Grigor Dimitrov and sealed victory after clinching a topsy-turvy second set that contained five breaks of serve. After Dimitrov broke Roddick in the ninth game of the second set to lead 5-4, the American smashed his bag repeatedly in frustration but immediately broke back to level at 5-5, saving a set point. Speaking about the incident, Roddick said: “I don’t know that I made a first serve that game, you know, so that was frustrating for me. I mean I felt like I was returning pretty well and hitting my forehand pretty well. Then all of a sudden I’m not putting a first serve in the court. So I was kind of pissed. I felt like I was getting it backwards a little bit.” In the late match at the Qi Zhong stadium, 18-year-old Tomic rallied from a set down to beat fifth seed Fish 4-6, 6-1, 6-4 to join Roddick in the third round. The 49th-ranked Australian had only won one match previously against top 10 players but levelled with two breaks in the second set and a single break in the ninth game of the decider earned him the win. Also in second round action, Swiss 13th seed Stanislas Wawrinka beat America’s Donald Young 6-7 (5/7), 7-6 (7/2), 6-2 and France’s Gilles Simon, seeded eighth, eased past Spain’s Albert Montanes 6-1, 6-1. Earlier, Germany’s Florian Mayer, the 15th seed, David Nalbandian 6-3, 6-4 to reach the third round and seventh seed Nicolas Almagro defeated Spanish compatriot Tommy Robredo 7-5, 6-3. In first round clashes, Serbian ninth seed Janko Tipsarevic crashed out to Feliciano Lopez of Spain 6-7 (2/7), 6-7 (3/7), dealing a heavy blow to his hopes of reaching the ATP World Tour Finals.
