After Mike Marjama’s recent retirement, the Mariners have been in desperate need of catching for their Minor League ranks. Per MLBTR, the Mariners have signed former Phillies backstop Cameron Rupp.
Rupp was released by the Phillies back in March and has since played for the Triple-A affiliates of both the Texas Rangers and Minnesota Twins.
Before that, Rupp was regarded as one of the better defensive catchers in the MLB. His defense carried him to one-win seasons in 2015 and 2016, as well as a near-one-win season in 2017.
The problem is his offense.
