The Boston Red Sox will put pitcher Koji Uehara on the disabled list due to a wrist injury Monday, according to the Boston Globe. The 40-year-old closer sustained the injury -- which may be a fracture -- when he was hit by a comebacker Friday, leaving Junichi Tazawa as the likely ninth-inning man in Boston. Uehara has excelled since coming to the major leagues from Japan prior to the 2009 season, with this year's 0.92 WHIP representing the sixth consecutive campaign in which he has posted a mark under 1.00. All in all, Uehara has closed 25 games in 27 opportunities while posting a 2-4 record, 2.23 ERA and 47 strikeouts with nine walks in 40.1 innings. If the injury does prove to be a fracture, it could potentially end Uehara's season, as the last-place Red Sox will have little reason to rush him back to the field.
