The Indians have now extended 19 invitations to players not on their 40-man roster.
Chulk, 30, has a career record of 7-14 with a 4.36 ERA in 244 appearances with the Blue Jays and Giants over the last six seasons. In 2008, Chulk went 0-3 with a 4.83 ERA in 27 appearances before he was designated for assignment midseason. He became a free agent at season's end.
Chulk could compete for a spot in the bullpen, but he'll have plenty of competition. Six spots are guaranteed to right-handers Kerry Wood, Jensen Lewis, Rafael Betancourt Joe Smith and Masa Kobayashi and left-hander Rafael Perez. Adam Miller, John Meloan, Ed Mujica and left-hander Rich Rundles are among the candidates on the 40-man for that seventh spot. Miller is considered the favorite, if he's healthy.
If nothing else, Chulk is a veteran addition at Triple-A Columbus who could potentially right himself and enter the Indians' big league picture. Chulk can request his release if he's not with the Major League club by May 15.
