BOSTON (AP) - Red Sox pitcher Carson Smith dislocated his pitching shoulder during a tantrum and went on the 10-day disabled list Tuesday, an injury Boston said could be major.

The 28-year-old right-hander was hurt when he threw his glove in the dugout after leaving Monday night's 6-5 loss to Oakland. He entered with the Red Sox trailing 5-4 in the eighth, allowed Khris Davis' leadoff home run, then retired three straight batters. Brian Johnson relieved to start the ninth.

Left-hander Bobby Poyner was recalled up from Triple-A Pawtucket. Poyner is 1-0 with a 2.25 ERA in seven games and eight innings with the Red Sox this season.
