The Cleveland Indians activated Betancourt from the 15-day disabled list Tuesday. The 31-year-old reliever has been sidelined since April 20 with a right upper back strain. In eight appearances this season, Betancourt is 0-0 with a 6.43 ERA over seven innings. To make room for him, the Indians optioned Jeremy Guthrie to Triple-A Buffalo. (Updated 5/16/2006)
