I thought Bard caught Martis.
Bard has caught Martis twice, while Nieves has paired up with him for 8 games in his career. The splits are pretty much the same for the two, except when Bard catches Martis has a .154 BAA and 0.33 SO/BB ratio vs. when Nieves catches Martis has a .221 BAA and 1.82 SO/BB. The sample size is much to small, though, to be useful.
