JABO: The Transformation of Matt Carpenter

Over the last few years, Matt Carpenter developed into one of the game’s most underrated stars by exceeding at the skill set embodied by the likes of Mark Grace and Joe Mauer over the last few decades; be extremely selective at the plate, rarely strike out, hit a ton of line drives, and create value through elite levels of walks and doubles.

From his rookie season of 2012 through the end of last season, no one in baseball took a higher percentage of pitches than Carpenter, and he ranked 14th overall in contact rate when he did offer at a pitch in the strike zone. Carpenter’s unwillingness to chase pitches out of the zone, and his ability to rarely whiff on swings in the zone, allowed him to post nearly even walk and strikeout rates in an era when pitcher dominance has become the norm. While he wasn’t a big power guy — he hit just 25 home runs during those three seasons — he made up for it by posting one of the highest line drive rates in the game, which allowed him to rank in the top 10 in doubles, so he wasn’t just a slap-hitting singles machine like some other elite contact batters.

This year, though, Matt Carpenter is different.

Nice one. I am less a fan of the new Matt Carpenter than the old one. But it is likely an aesthetic judgment as you discuss at the end. The wRC+ is the same… It just feels/seems like he helped the team more by starting rallies with doubles and walks than by hitting homers. But man oh man if he found some sweet spot between the two approaches next season! Wow!

Oh yeah, the 2015 swing % image shows why he has been getting rung up on the down and away called strikes at such a crazy rate: he just refuses to swing at those pitches. He has swung at a much lower rate in that area than previously. Last I checked I think it was he and Goldy who were called out on those strikes most often…

Really nice article.
