During Spring Training, it is very common to see an emphasis on defense, and this is certainly the case for the Nats. In their time in West Palm Beach, Davey Martinez and the Nationals staff have been laser focused on defense.
Last season, the Nationals were not a very good defensive team. Their 109 errors was the third most in baseball, and the team was weak in some notable spots. CJ Abrams was particularly disappointing on the defensive side of the ball. While he cut down on his errors, he graded out as a highly negative defender.
