BOSTON � The Boston Red Sox placed shortstop Julio Lugo on the 15-day disabled list with a left quad strain today.

Lugo was injured Friday night while running out an infield single in the ninth inning of Boston's 7-3 loss to the Baltimore Orioles. Lugo began to limp as he approached first base, then dropped to ground shortly after hitting the bag.

The Red Sox on Saturday called up shortstop Jed Lowrie from Pawtucket to replace Lugo. Lowrie was in the lineup for Saturday afternoon's game with Baltimore.

Lugo was hitting .268 with 12 steals for Boston this season. Lowrie hit .310 with 7 RBI in 17 games with Boston earlier this year.
