Guessing the Fate of April’s Underachieving Hitters
For the first month of every baseball season, I’m a bit notorious for simply answering “April” as the convenient, one-stop-shop for questions relating to why someone’s favorite player is hitting .150. Once we start heading into May, telling people to be patient when 1/6th of the season is already over becomes an increasingly unujustifiable task. While rebuilding teams are in a place at which they can be patient, avoiding judgment is tricky for contenders, especially when every division leader is in first place by fewer than three games.
So let’s get out the guillotine and guess who can be saved and who is a lost cause.
Ryan Braun, Milwaukee Brewers
I remain quite torn about the state of doneness of the Hebrew Hammer. On one hand, he can still hit the ball with authority as seen by the fact that his average exit velocity, dipping under 90 mph, isn’t all that different from the numbers in 2016 and 2017, years in which Braun was still a contributor offensively. If you dig deeper into his pitch-by-pitch stats, Braun appears to be going dead-red for fastballs, and despite a career-low contact rate, he is actually making contact with fastballs at better-than-career-average rates (14.6% whiff/swing rate in 2019 vs. 19.8% career). But other than fastballs, he’s making much worse contact, missing almost half the changeups and sliders he’s offered at (career rate under 30%).
It makes me wonder about Braun’s bat speed. To my naked eye, it looks like he’s trying to compensate for decreased bat speed by making contact with his bread-and-butter pitch (Braun was one of the best fastball hitters in baseball in his prime). He also suggested he was changing his swing in order to hit more home runs. It’s unfortunate that swing speed isn’t one of the things you can get easily, but Alex Chamberlain identified stats that correlate with swing speed when reverse-engineering the scanty data available a few years ago. Isolated power, xwOBA, and contact rate all have a relationship, and in each of the three, Braun is at his career’s nadir.
I think there’s still hope for Braun, but if his bat is slowing down, I wonder if he’s taking the wrong approach in trying to hit for more power. A player with slower bat speed but who is also pulling the ball more (57% compared to 38% career) seems like one trying to cheat on the fastballs. I don’t think Braun’s as doomed as some on this list, but I think that he’d be better off not trying to capture his early-career power because it’s making him a one-dimensional hitter.
