Derek Jeter has been scratched from the Yankees lineup because of stiffness in his left ankle.
Joe Girardi said that Jeter was flexing the ankle a lot during batting practice. Jeter eventually went to trainer Steve Donohue, who then told Girardi, who made the lineup change. Girardi is not sure what this means long term. Could be just a day. Could be a sign of things to come.
For now, let's not overreact to this. The guy is coming back from an ankle injury so I'm sure this was to be expected this early on in the recovery process.
