The Astros have placed catcher Brian McCann on the seven-day concussion disabled list, retroactive to Saturday, and selected the contract of fellow backstop Juan Centeno from Triple-A, per Brian McTaggart of MLB.com (on Twitter).

McCann is now the second prominent Astro to hit the DL since Saturday, joining ace Dallas Keuchel on the shelf. Like Keuchel, McCann has thrived for the 29-14 Astros, owners of the majors’ best record. McCann, whom Houston acquired from the Yankees in an offseason trade, has slashed .269/.365/.454 with six home runs and as many walks as strikeouts (17) in 126 plate appearances. On the defensive side, the 33-year-old has continued a careerlong trend of serving as a plus pitch framer, according to Baseball Prospectus.

Fortunately for the Astros, they do have a quality reserve behind McCann in the power-hitting Evan Gattis, who has also performed well this season. Centeno, an offseason minor league signing, will back up Gattis. The 27-year-old Centeno has been great this season at Triple-A, where he has slashed .368/.395/.487 line in 83 PAs, though he hasn’t been nearly as successful in the majors. In 258 big league PAs, including 192 with the Twins last year, Centeno has hit .236/.290/.338. Behind the plate, BP ranked him among the majors’ worst framers in 2016.
