Andy Pettitte has big plans for this season — 200 innings, 20 wins, not missing any starts. He knows, as he put it, “The Yankees are paying me a lot of money and I have a big responsibility and I want to uphold that responsibility.” And that’s why, as much as he wanted to pitch for Team USA in the World Baseball Classic, he ultimately decided not to, especially once he heard the Yankees’ take on it. “They didn’t want me to play,” Pettitte said. “They weren’t crazy about it and I understand it. I spoke with (GM Brian Cashman) and Joe (Girardi). They were supportive, ‘If you decide to do this,’ but obviously were hoping it was something I wouldn’t do.” Pettitte himself was leery of getting hurt. Plus the tournament would have taken him out of Yankee camp for much of March. “I guess if something goes wrong, I want it to go wrong when I’m playing for this club,” the 40-year-old said. The lefthander was in a good mood after the Yankees’ first workout for pitchers and catchers at Steinbrenner Field on Wednesday. He laughed at how “weird” it was that, one year ago, he was just a retired player back for a stint having fun as a guest instructor. Then, of course, he came out of mothballs after just one season away. He made nine starts for the Yanks before suffering a broken leg, but then returned for three more in September and two in the postseason. Read more:
