Tabata was diagnosed by Dr. Mark Baratz with a small avulsion fracture on the dorsal side of the fourth metacarpal of his left hand. He will rest and receive treatment for 10 days to allow the bone to heal. Tabata will be re-evaluated at that time. He first experienced pain while swinging the bat in the cage before a game on Aug. 24.
"He had the wrist looked at," Pirates manager Clint Hurdle said. "I'll just tell you this -- we're going to put him down for a volume of days, we haven't decided on an exact number, but we're just going to set him down."
Tabata hit .266 with four home runs and 21 RBIs in 91 games this season. He missed a big chunk of the year with an injured left quad muscle.
