John Isner and Tomas Berdych won three-setters to book third round tickets in Miami, while Tsonga saw off Troicki in straight sets.
Twentieth seed American Isner smashed amazing 24 aces and conceded no double faults in a second round match against Ivan Dodig of Croatia (9 aces, 7 DFs), but still had a tough job beating his rival. Dodig claimed the first set and had a one break advantage in the next one. He could not hold on to the lead though as Isner clawed back by 4-4 and made it one set each in the end. A real drama was yet to follow with both players dropping a couple of service games before deciding the winner in a tie-break. Isner soon prepared a triple match ball and wrapped the match up by converting the third one. He moved on to the next round with a 4-6, 7-5, 7-6 (5) tight victory.
Sixth-seeded Frenchman Tsonga did not play with his fan’s nerves as much as Isner, although he could not shake off Viktor Troicki until the end of the first set. The Serb actually wasted a set ball at 5-4 in the opener and another one in the tie-break before Tsonga ultimately wrapped up the up-and-down set. The Frechman used the momentum to break Troicki in the beginning of the second set, yet he was very lucky to confirm it after fending off four re-break balls. The unseeded Serb kept threatening, but gave away a serve again in the last game of the clash. End result: 7-6 (6), 6-3.
Fourth seed Berdych will be even less delighted with his second round performance as he was stretched to three sets by Daniel-Gimeno Traver of Spain. What is more, the Spaniard grabbed the first set and would not let the favorite break him in the next one. The tie-break followed where Berdyh went a mini-break down first before turning the proceedings around to force a decider. He was not brilliant in the final set either, but managed to obtain a double break lead by 5-2, saving four break balls along the way. He had no problems serving the match out in the end, thus moving into the next round with a 5-7, 7-6 (3), 6-2 difficult win.
