What Christian Yelich Has Changed
You couldn’t blame Eric Hosmer or Christian Yelich if they got sick of hearing about Statcast. Anyone who’s ever played with the basic tools has been able to discover two things: (1) historically, Hosmer and Yelich have hit the ball hard, and (2) historically, Hosmer and Yelich have hit the ball on the ground. It became easy to wonder what might happen if Hosmer and Yelich set their sights on the skies. It just so happened that, last offseason, both of those players changed teams. Might they have also been willing to change their swings? It’s not that it wasn’t interesting. It just started to grow a little tired.
Hosmer hasn’t changed. That much I can tell you. Through five months of baseball, he’s got a below-average batting line and a below-replacement WAR. He has the highest ground-ball rate he’s ever posted. But then, Yelich is currently sitting on a career-high wRC+. He’s sitting on a career-high slugging percentage. He’s also technically sitting on a career-low ground-ball rate.
Don’t get the wrong idea, though. Yelich’s average launch angle hasn’t budged from last season to this one. He remains a ground-ball and line-drive hitter. In part, he’s just benefiting from playing in Milwaukee instead of playing in Miami. And in part, he’s benefiting from another change. It’s not one that has to do with his swing. Rather, it’s one that has to do with his approach.
