"I don't think we need a veteran backup catcher. If it works out we're open minded to that," general manager Matt Klentak said. "But Andrew Knapp just finished age 25 season in Triple-A. He has a full year of at-bats in Triple-A. At some point for both he and Alfaro we're going to have to find out what those guys can do at the big league level. During 2017 we'll have to find out – not just about those two guys – but others."
