The Astros have signed catcher Juan Centeno to a minor league deal with an invitation to major league spring training.— Jake Kaplan (@jakemkaplan) December 20, 2016
The Twins, of course, signed Jason Castro, who had been Houston's No. 1 catcher, in large part because of his defensive skills -- pitch framing in particular. And now Centeno, whose pitch framing is suspect at best, has landed with the Astros.
It's not an even exchange, of course. Castro isn't replacing Centeno on the Twins roster so much as he's replacing Kurt Suzuki (who, by the way, remains a free agent). Centeno isn't replacing Castro in the Astro's plans, either; he may be more likely to be what he was when the Twins signed him last winter -- a catcher for the high minors who would be available if something goes wrong with the big club.
Still, it's at least slightly ironic, this "exchange" of left-hand-hitting catchers with different strengths.
