NEW YORK -- A pair of injuries hit the New York Yankees on Tuesday, one seemingly minor and the other more serious.
Meanwhile, earlier in the day, starting pitcher Michael Pineda, currently serving a 10-day suspension for using pine tar in a game against the Red Sox, pulled himself out of a simulated game in Tampa, Fla., after one inning, complaining of soreness in a back muscle on his pitching side.
X-rays on Ellsbury's hand came back negative. Girardi said Ellsbury might miss two games. Pineda, on the other hand, has a Grade 1 strain of the teres major muscle in his back, the Yankees announced Tuesday night. He will be shut down for 10 days and probably will not pitch for three to four weeks, general manager Brian Cashman said.
If Pineda is placed on the disabled list, it is unclear whether the Yankees will be able to add a player to the major league roster; currently, they are playing a man short since they were not allowed to replace Pineda while he is under suspension.
It was unclear how Ellsbury suffered his injury.
"It's just been bothering him for a few days, but he's been playing through it," Girardi said. "The test came back good, so we know there's no structural damage. It's just been sore."
Ellsbury leads Yankees regulars with a .312 batting average and .369 on-base percentage, and is second on the team with 11 RBIs. Brett Gardner played center field and batted leadoff against the Mariners in Ellsbury's place.
