He was more of a backup catcher, really. Maybe our expectations were too high.
Before the praise of the new guy, start with the obvious: Trevor Brown has a career .616 OPS in the minor leagues. This was the first season out of four in which he posted an on-base percentage over .300. If you're expecting Chris Stewart-levels of offensive competence, the burden of proof is on you. The stats aren't there. Not yet.
And now for the praise: Brown looks solid defensively. In a hilariously small sample, he's down with Hector Sanchez when it comes to framing numbers, but he passes the eye test.
