Swisher's Home Run Caps a Sweep BALTIMORE - The Yankees concluded their season-opening road trip on a frigid Wednesday night at Camden Yards, where every batted ball seemed to sting the hands - except for the last one that Nick Swisher hit. Only a fraction of the 22,919 fans in the announced crowd were still present in the top of the 10th inning when Swisher drove a full-count pitch from Kevin Gregg deep into the stands in right-center field as Mark Teixeira danced off second base, giving the Yankees a two-run lead. With dozens of fans dressed in orange Orioles pullovers streaming toward the exits, Mariano Rivera came into the game in the bottom of the 10th and closed it out for the 6-4 victory. It was the second time in two nights that the Yankees won with a pair of runs in extra innings. They headed home having swept the Orioles in the three-game series to even their record at 3-3. After a day off Thursday, they host the Los Angeles Angels on Friday in their home opener. The Yankees and the Orioles each had chances to win Wednesday's game earlier than extra innings, but the Yankees were the ones to capitalize. Even after Eduardo Nunez was picked off for the second out in the top of the 10th, Teixeira hit a bloop double and Swisher connected for his second home run of the season. In the bottom of the ninth, Orioles left fielder Nolan Reimold hit a two-out double off Rafael Soriano and J. J. Hardy walked on four pitches. The Yankees decided to have Soriano walk the No. 3 hitter Nick Markakis to load the bases so he could face the right-handed hitter Adam Jones. The strategy worked as Soriano struck out Jones. C. C. Sabathia did not have his best command, and his pitch count soared after the first inning on a night when the Yankees needed innings from him. But he managed to last six innings on 112 pitches, and when the Yankees tied the score with a run in the seventh, Sabathia avoided a loss for a second straight game. The night before, the Yankees went deep into their bullpen as the game lasted 12 innings. Before Wednesday's game, Manager Joe Girardi said he was not likely to use Dave Robertson, Cory Wade or David Phelps. That put even more pressure on Sabathia to go deep into the game. "We're going to need some distance out of him today," Girardi said during batting practice, "there's no doubt about that. Our bullpen's a little beat up. Boone Logan pitched one and two-thirds perfect innings of relief of Sabathia, and Soriano got the final out of the eighth inning before escaping the ninth. The Yankees missed a chance to score in the top of the eighth when they had a runner at third with one out after Alex Rodriguez's ground-ball single. But Swisher struck out looking and Russell Martin went down swinging. Sabathia gave up two runs in the second and two more in the fifth, but in the top of the sixth, Curtis Granderson's run-scoring single scored Martin to even the score at 4-4. Granderson, who came into the game batting .150, also hit a two-run homer in the first inning. In the top of the fifth, the Yankees sent six batters to the plate and only recorded one hit, a bloop single to left by Brett Gardner. But it was enough to score a run. Raul Ibanez led off with a walk, and Orioles starter Jake Arrieta hit Martin with a pitch. Gardner loaded the bases with his bloop, then Ibanez scored when Derek Jeter grounded out to the right side. The Yankees struck early against Arrieta. Jeter led off the game with a double into the right-field corner, but he did not stay at second as Granderson followed with a home run to right. At the time, it seemed as if the Yankees might pile on from there, but Arrieta regained some control and the game would not be decided for more than three and a half chilly hours. The Yankees announced that Jorge Posada would throw out the ceremonial first pitch before Friday's home opener. Posada, who played 17 seasons with the Yankees, announced his retirement in January. Derek Jeter, Posada's closest friend on the team, said he would not be catching the pitch, but another one of Posada's longtime teammates volunteered for the duty. "Definitely, I would like to," said Mariano Rivera, who played almost all of his career with Posada. ... Rivera earned his first save of the season Tuesday, and the 39th of his career at Camden Yards. Rivera broke the record Wednesday.
