What It Means:

On Wednesday, Fister utilized an opt-out clause in his one-year contract with the Angels. He was released and sent to waivers, where, even if claimed, he could reject the claim and become a free agent. But, with an offer to become a member of the Red Sox' 40-man roster, expect Fister to insert himself into the rotation, at least for the time being.

In 3 starts at AAA-Salt Lake, Fister posted a respectable 3.59 FIP in 15 2/3 innings.
