Yankees catcher Jorge Posada was frustrated after the team was swept at the hands of the Red Sox this weekend as Fenway Park. "It was a tough weekend; we could have won two of three," Posada said. Mariano Rivera blew a save on Friday night, New York coughed up a 6-0 lead on Saturday, and Sunday's loss was highlighted by Jacoby Ellsbury's stealing of home against Andy Pettitte. "Obviously, that's frustrating. Jorge told me to watch him. I was in the windup, I should have been in the stretch," said Pettitte. "I figured if [Ellsbury] took off I would go through my windup and throw him out."
