Clint Barmes was the Pittsburgh Pirates’ primary shortstop this season, but after going 0-for-2 with an error against the Cardinals in Game 1 of the NLDS manager Clint Hurdle has decided to bench him for Game 2.
Jordy Mercer will start at shortstop, which is definitely an offense-for-defense swap. Mercer hit .285 with eight homers and a .772 OPS in 365 plate appearances this season while seeing action at shortstop and second base. Barmes, meanwhile, hit just .211 with a .558 OPS and was more or less just as bad for the Pirates last year too.
