Swapping Return Positions Fuels Rally for the Bryans Eduardo Munoz/Reuters Mike Bryan, left, and his twin, Bob, switched sides for their serve returns in their match Sunday. For the twins Bob and Mike Bryan, one lost set was enough to change a winning formula. The Bryans, the top-seeded doubles team, had dropped the first set in a tiebreaker to the Canadian team of Daniel Nestor and Vasek Pospisil. So they swapped their return positions before the second set, switching the left-handed Bob to the left (ad) side of the court, and the right-handed Mike to the right (deuce) side. The tactic did not pay dividends immediately, and it seemed to work against them as Nestor and Pospisil broke for the first time in the match to take a 4-3 lead in the second set. But starting with the next game, the Bryans were able to exploit the faltering serve of the 40-year-old Nestor, breaking him in that game as well as his next service games. The Bryans went on to close out a 6-7 (1), 7-5, 6-2 victory, punctuating the comeback with a signature chest bump. Bob said he came up with the idea of the switch, a move the brothers have used before but not in the last three years. "I thought it might throw a different wrinkle at them, and it maybe caused a few double faults, who knows," Bob said in his postmatch on-court interview. But we're lucky to be alive here. He added at his news conference: "We did have a little confidence because we have used that tactic against Nestor in the past. I was telling Mike like in the beginning, he's getting so much width on the wide serve and the deuce and he's killing me on the T. I don't think I'm going to win too many points on Nestor's serve. Let's mix it up. We are going to be in another breaker unless we change it. Not only does it keep their United States Open run alive into the quarterfinals, but it does the same for their larger bid: to win all four Grand Slam men's doubles title in a calendar year. The Bryans have completed what they call a Golden Bryan Slam, including their Olympic gold medal and United States Open titles from last year to go along with their titles from this year's Australian Open, French Open and Wimbledon.
