Andrew Alvarez Attacks Batters With an Atypical Breaking Ball Combination

Tuesday night’s outing wasn’t anything to write home about — four hits and five runs allowed over 5 2/3 innings in a 6-3 Washington Nationals loss to the Houston Astros — but Andrew Alvarez is having a good season. Across 12 appearances, including six as a starter, the 27-year-old southpaw from Los Alamitos, California has tossed 47 frames with a 3.64 ERA, a 2.97 FIP, and a 25.4% strikeout rate. Pitching in his first full big league season, he has been one of the few bright spots on a staff that is statistically among the worst in the majors.
Velocity isn’t his carrying tool. At 92.3 mph, Alvarez’s fastball ranks in just the 18th percentile for velocity. What the 2021 12th-round pick out of Cal Poly brings to the table is a five-pitch arsenal that leans heavily on a somewhat atypical breaking ball combination. In terms of usage, his mix has been 29.8% four-seamers, 28.7% curveballs, 24.7% gyro sliders, 13.9% sinkers, and 2.9% changeups.
The left-hander’s self-identity as a pitcher pretty much mirrors his profile.
“The Nationals have certainly helped me grow my game and understand who I am,” Alvarez told me prior to a recent game. “I’m not someone who is going to overpower you with stuff, but rather keep you off balance, get some weak contact and a little bit of chase here and there, a little bit of swing-and-miss. For me, it’s more about moving the ball around, changing speeds and locations, and [getting] a lot of groundballs”
Alvarez’s 57.1% groundball rate is tied for sixth highest among hurlers with at least 40 frames on the season. Moreover, his chase rate (57th percentile) and whiff rate (65th percentile) are both comfortably above league average.
And again, Alvarez’s breaking ball combination is atypical, as well as his primary attack plan against most hitters. Read the rest of this entry »
