Pettitte to Start Sunday for Yankees Vs Seattle Andy Pettitte is set to rejoin the New York Yankees and start this Sunday at home against the Seattle Mariners. "Everybody's in agreement he's not going to benefit from any more time below," Yankees general manager Brian Cashman said Tuesday. Pettitte retired after the 2010 season and sat out last year. The lefty, who turns 40 next month, returned to the team in spring training and has been pitching in the minors.

Murante) MAGS OUT NO SALES Close Pettitte threw five shaky innings Sunday in his first Triple-A start in his comeback, allowing five runs and eight hits. He has pitched four times in the minors this year with a 3.71 ERA in 17 innings. I think the fans are excited. I know Andy's really excited," Cashman said. The plan for Pettitte to start this weekend could shift if rain hangs around, he said. "We have weather issues all week and reserve the right to change our mind," Cashman said. Pettitte is 240-138 lifetime, spending 13 years with the Yankees and three seasons with Houston. The Yankees have been eager for Pettitte to rejoin their rotation. They recently demoted starter Freddy Garcia to the bullpen and Phil Hughes had been struggling until a good start last weekend at Kansas City.
