Victor Martinez – Martinez last caught a game in 2014 and has been used almost exclusively at DH with some time at first base. He played two seasons with the Red Sox hitting a very solid .313. Martinez was acquired from Cleveland via trade of Justin Masterson and Nick Hagadone. He left for the Tigers as a free agent and almost captured a batting title in 2014.
Ryan Hanigan – As solid a defensive catcher as one will find, Hanigan came to Boston for Will Middlebrooks. He twice led the National League in CS% and has a great reputation as a handler of pitchers. With the Red Sox, injuries forced Hanigan to assume more of a role as a regular. He finished his Boston stint of 89 games with a .219 average. Now he’s with Colorado.
Jarrod Saltalamacchia – Now playing for Buffalo, his claim to fame is defensively playing himself to the bench in the 2013 playoffs. The Red Sox picked him up from the Rangers for three minor league players. Salty left Boston via free agency after hitting 55 home runs and batting .243 in 355 games with the Red Sox.
