The Other Times We Saw This Ryan Zimmerman
Ryan Zimmerman is off to a great start. We’re only 26 games into the season covering 104 PA, but anytime you’re running a .427/.462/.875 line, it’s worth celebrating. Among qualified hitters entering play on Thursday, Zimmerman led the league with a 241 wRC+. This is particularly noteworthy because, measured by outcomes, Zimmerman had a terrible season in 2016. Zimmerman posted a 67 wRC+ in 467 PA last year after many years as an above-average hitter.
During the offseason, Jeff Sullivan noted that Zimmerman’s 2016 probably didn’t portend doom. Jeff pointed out that Zimmerman was hitting the ball pretty hard in the air, but he simply wasn’t collecting extra-base hits at a rate consistent with that contact quality. Erstwhile FanGrapher Mike Petriello made a related argument, recognizing that Zimmerman was making hard contact, but that he simply wasn’t hitting the ball at a steep enough angle to turn that hard contact into productive contact.
I probably don’t have to tell you where this is going. This season, Zimmerman is hitting the ball a bit harder than last year, 93.6 mph on average vs, 92.5 mph in 2016, but his average launch angle has increased from 9.0 to 11.7 degrees in 2017.

But you don’t need fancy Statcast numbers to notice this difference. His fly-ball and ground-ball rates are plenty clear. Zimmerman has joined the ranks of so many players who are trying to hit more fly balls. And at least so far this season, it’s working quite well for him.
