The Rockies have informed reporters, including Thomas Harding of MLB.com, that they have signed catcher Grayson Greiner to a minor league deal. He had been in camp with the Twins on a minor league deal but was recently released. Harding adds that Rockies’ minor league catcher Willie MacIver will be out for the next six to eight weeks due to a shoulder issue.
Greiner, 30, has appeared in each of the past five MLB seasons as a backup/depth catcher, getting into 139 total games in those five campaigns with the Tigers and Diamondbacks. He’s drawn walks at a decent 9.1% clip but struck out in 32.2% of his trips to the plate. His .201/.275/.307 batting line amounts to a 58 wRC+. He has -8 Defensive Runs Saved in his career with a negative grade from FanGraphs’ framing metric.
The Rockies have just a pair of backstops on their roster at the moment in Elias Díaz and Brian Serven. MacIver was set to be the club’s regular catcher in Triple-A but it looks like he’ll now miss the next couple of months with that shoulder issue. Greiner will presumably take over that responsibility and could be first in line for a call-up to the majors should another injury arise. One of the club’s top prospects, Drew Romo, is a catcher, though he just reached Class-A Advanced last year and will likely head to Double-A to start this season.
