Yankees right-hander Masahiro Tanaka was placed on the 10-day disabled list Saturday with mild strains in both hamstrings after he was hurt running the bases a night earlier.
The team doesn't have a clear timeline for Tanaka's return, but general manager Brian Cashman estimated that he will be out a "month" after he was asked for a timetable multiple times by reporters Saturday at the ballpark.
