Greg Bird and Starlin Castro need playing time to get back to the Yankees, so their rain-shortened game with Triple-A Scranton/Wilkes-Barre wasn’t especially helpful. Before the Yankees beat the Tigers 13-4 at Comerica Park, manager Joe Girardi said Bird was “swinging great,” but declined to put a timetable on his potential return after missing much of the season with a right ankle injury. “Part of it, though, is we’ve got to make sure he’s ready to go back-to-back every day in the field and play three or four days in a row,” Girardi said of the first baseman, who went 0-for-1 with a sacrifice fly as the DH. As for Castro, who is rehabbing his second hamstring injury of the year, Girardi said “we’re happy with the way he’s progressing. We’ve got to make sure he’s running fine and that there’s no pain and no restrictions.”
