The Yankees' Jason Giambi was back in the lineup on Saturday against the Seattle Mariners. Giambi was scratched from the lineup Friday night in Seattle after the Yankee slugger took batting practice. Giambi has bone spurs and plantar fasciitis in his left foot and was expected to go on the disabled list if the condition did not improve significantly. He is taping the injured foot for now but is waiting for orthotics to alleviate the pain. Giambi said he thought the problem started in Texas the first three days of May. Before being back in the lineup on Saturday, Giambi missed three straight games.
