Injuries forced the Yankees to play veteran Jorge Posada at catcher on Saturday night for the first time this season. Posada stepped in after starter Russell Martin took a foul tip off his right thumb during the team's 6-0 loss to the Angels. Francisco Cervelli was already out with concussion-like symptoms. "I got a chance to get back behind the plate," Posada said. "I have my equipment with me. I'm an emergency catcher, like I was today. Joe [Girardi] said, 'What do you think?' So I said, 'Well, if you need me, I'm there.' He said, 'Go ahead. It's like riding a bike.' I was excited. It was fun. I'll be sore tomorrow, but I'll sleep well tonight." When Posada, 40, entered in the third, Howie Kendrick singled and then tried to steal. Posada, who hasn't even played an exhibition game behind the plate this season, gunned down Kendrick at second.
