Mike Mussina won his twentieth game of the season on Sunday as the Yankees defeated the Red Sox. New York beat Boston 6-2, thanks to a strong performance from Mussina. He pitched six innings of shutout ball, striking out three batters and walking two. Mussina had never won twenty games in his career, coming close several times, and is now the oldest pitcher in MLB history to reach to milestone for the first time. The righty, who will turn 40 in December, finished the season with a 20-9 record and a 3.37 ERA and 150 strikeouts in 200 1/3 innings for the Yankees. He will be a free agent this winter, and hasn't yet decided whether or not he'll pitch next season. The Red Sox tacked on two runs in the eighth inning, to make the score 3-2, but the Yankees added three insurance runs in the ninth inning on Jonathan Papelbon. After the final out, recorded by Mariano Rivera, each one of his Yankee teammates took the time to congratulate Mussina. "It sounds pretty good I guess, I've been close," Mussina said after the game. "The guys played real solid, it's been a fun day." He revealed that Joe Girardi told him earlier in the week that he'd have all the arms in the bullpen ready to help Mussina if needed. "It took me a long time to get to something like this," he said of being the oldest pitcher ever to accomplish the feat. His season is over, but he's not sure if he'll call it a career just yet. "I don't know, we gotta get away from it a little bit," Mussina said about his possible retirement. "If it is [his last game] this was kind of a nice way to end it."
