The good news is that Toronto had enough resources to recently make a three-year offer to Cecil. That money can be allocated to finding another reliever to take his place, and there are several alternatives on the free-agent market who are worth considering.

He struck out at least 10 batters per nine innings in each of the last four seasons and had a sub-3.
