Joba Chamberlain has made the Cleveland Indians as a non-roster invitee.

"He accepted the challenge," Terry Francona said Saturday. "He came out in January and been a teammate since Day 1. He has really thrown the ball well this spring. He likes to compete and wants to win. Joba will be a real valuable piece."

In eight innings this spring, Chamberlain has given up seven hits and three runs. He walked five and struck out seven and has an ERA of 3.38.

Chamberlain spent last season with Detroit, Toronto and Kansas City.
