 He mixes in a curveball, a cutter, and a changeup, and Eflin, when he's on, gets the ground ball out. He is only allowed on the season 12 home runs, so you look at six walks, 12 homers, you're more likely to get a home run against Zach Eflin than walks. Nationals don't have a whole lot of history against him. The best history for the Nationals as far as any hitter, Luis Garcia, four for seven with a double in career matchups against Zach Eflin, who's in his second year.
