Yankees' first baseman Jason Giambi is happy playing in New York but said on Tuesday that he still has rather lofty goals to achieve before retiring, according to The New York Times. ?I?d like to play until I?m 40. My body feels great, and I?m taking care of it. I?d love to play that long," he said Tuesday upon returning to Oakland where his career began in 1995. ?I loved playing here,? Giambi said. ?It was fun. I had a ball. I have a ball now. I don?t think I?ve really changed.? He is in the final year of his current contract with the Yankees. ?They?ve got great young players over here,? he said of the A?s. ?I don?t know what would go with the situation. I love playing in New York, and I still have a World Series to win.?
