SAN DIEGO -- The Boston Red Sox have activated reliever Koji Uehara from the disabled list.
Uehara had been out since July 20 with a strained pectoral muscle. The right-hander is 2/3 with a 4.50 ERA in 39 games.
He is expected to be available on Tuesday for Boston's second game of a three-game series against the San Diego Padres.
The Red Sox also recalled catcher Christian Vazquez and right-handers Heath Hembree and Noe Ramirez from Triple-A Pawtucket on Monday.
