2. Joe Thatcher

A former product of the River City Rascals, Thatcher has bounced around with four different teams since debuting in 2007. Although various control problems have caused Thatcher to relocate in the past, he could bring valuable leadership to a relatively young bullpen.

Thatcher is not a typical go-to strikeout pitcher, but his ability to limit big hits has helped him compile a respectable major league career. The 34 year-old only allowed 11 home runs in the last five seasons, rejuvenating his career with the Houston Astros last year with his best earned run average since 2010.

Reasonable contract: 1 year, $2.5 million
