The Indians activated pitchers Carlos Carrasco, Rafael Perez and Josh Tomlin from the 60-day Disabled List.
The Tribe also claimed pitcher Blake Wood off outright waivers from the Kansas City Royals.
Wood, 27, missed the entire 2012 season after experiencing right elbow soreness in spring training that eventually led to reconstructive surgery on May 25. The Georgia Tech alum, who was the Royals third round pick in the 2006 draft, owns a two-year Major League career record of 6-6 with a 4.30 ERA in 106 relief appearances.
The hard-throwing right-hander was a mainstay in the Kansas City bullpen in 2011, going 5-3 with a 3.75 ERA in 55 games.
