He was replaced in right field by rookie Colin Curtis, the hitting star of Wednesday's win over the Angels, and in his customary No. 2 slot in the lineup by Derek Jeter, who was moved down from the leadoff spot. Brett Gardner, originally batting ninth, was leading off. Curtis batted ninth.
Swisher said he felt pain in the Achilles tendon upon awakening Friday morning despite suffering no discomfort in Thursday night's 10-4 win over the Royals, in which he had a two-run double in the eighth inning.
Swisher was seen with trainer's tape around his left ankle in the clubhouse Friday afternoon, but he went out and took his normal round of batting practice. "Then I tried to do some running and I couldn't go," he said. "So, they told me to take it in."
Swisher, who described the area as sore to the touch, said he received treatment in the trainer's room after batting practice, but that no MRI had been performed. "I don't do MRIs," he said. "Claustrophobic."
The Yankees have made no official announcement of his status, but Swisher said, "I probably just need a day or so."
Swisher missed four games in May with tightness in his left biceps.
