"I thought [Pierzynski] did a good job yesterday. It's yesterday driven," Matheny explained. "He did a nice job. You look at two of those hits we gave up in the first [inning] and the balls were neck high. And I thought [Pierzynski] put together a real nice swing in left-center. Hit today [without the wind], it's probably a double. I think the potential he brings offensively, the experience, and he didn't hurt us defensively."
Pierzynski caught Game 4 starter Shelby Miller six times this season, with Miller posting a 4.29 ERA with Pierzynski behind the plate. It was lower with Yadier Molina (3.57) and Cruz (3.80), though the sample sizes with both Cruz (23 2/3 innings) and Pierzynski (33 2/3 innings) were small.
As for looking for the better offensive matchup against Giants starter Ryan Vogelsong, Matheny didn't have many data points to work with. Cruz has never faced Vogelsong, while Pierzynski is hitless in two previous at-bats against him.
