Per FederalBaseball.com, the 24-year-old Catcher (drafted in the 6th round in 2016 by the Nats) is “solid defensively”, handles pitchers well, and leads the defense.
In 2018, Barrera hit .263, with 6 bombs, 24 RBI, and 68 hits in 259 AB’s. Barrera currently sits 14th in the Nats prospect list per MLB.com (list was from 2018, new prospect list comes out this month). The consensus seems to be his bat has pop, but sometimes pulls the ball way too much and doesn’t have much self-control at the plate.
As you can tell in this video, he’s a strong dude with a lot of raw power, the question will be if he can be consistent and work his way up through the Nats ranks.
Overall this seems to just be a good experience builder for Barrera, don’t expect him to be on the big squad for a few years, if ever.
