I just wrote a little bit about Joc Pederson making gains in his ability to make contact. The first commenter underneath got me thinking about Javier Baez. In the Pederson post, I began by reflecting on George Springer, but Baez was a little like Springer to an even somehow more extreme degree. When Baez was a prospect, it’s possible no one else had his maximum bat speed. But at the same time, few shared his propensity for swinging and missing. Fold in an over-aggressive approach and every single at-bat was boom or bust.

Baez got extended playing time as a rookie in 2014. During the PITCHf/x era, there have been more than 3,000 player seasons with at least 200 plate appearances. Baez posted the lowest contact rate out of all of them, at 59%. He wasn’t too hard to diagnose. Barring something almost unbelievable, Baez would need to get better at contact in order to have a real big-league career.

Good news! Javier Baez is making it. He’s 23, he has a league-average wRC+, and this is how his contact has gone:

He still misses the ball, and he still swings at a whole lot of pitches out of the strike zone, but where Baez as a rookie struck out an impossible 42% of the time, now he’s down to 25%. Javier Baez is putting things together. He should factor firmly into the Cubs’ plans, if nothing else but as a valuable trade asset. The bat is meeting the ball more often, and that was always going to be the struggle.

Shifting gears, turn your attention to the Royals. Last offseason, the Royals re-signed Alex Gordon, getting something of a hometown discount in the process. I wrote about that, and here’s a quick excerpt!

[…]one, Gordon shouldn’t hit the wall all of a sudden[…]

Gordon this year has been worth 0.3 WAR. After back-to-back wRC+ marks of 122, this year he’s down at 77. Even more troubling, Gordon hasn’t been hitting the baseball. His approach and his results were always consistent. In a sense I guess they might still be considered consistent, but they are also much much worse. Gordon’s career contact:

There’s nothing subtle about that. And you could blame a wrist injury he sustained toward the end of May, but there’s something curious — Gordon, before that, batted 166 times, with bad offense and an elevated strikeout rate. Gordon, after that, has batted 171 times, with bad offense and an elevated strikeout rate. Alex Gordon was having problems making contact before getting hurt, so I don’t know what one’s supposed to make of that. Gordon has gone through ruts before, and he’s earned the benefit of the doubt. But this is worrisome, not just because Gordon is a franchise legend, but also because the Royals are a team that can’t afford to spend such big money on underachievers. Don’t sleep on Gordon as one of the big reasons why these Royals probably aren’t getting back to the playoffs.

Baseball is wonderful and baseball is horrible. There’s evidence for both of these everywhere, but Baez and Gordon are stuck in my mind. As recently as 2014, Gordon had the higher wRC+ by 69 points. He had the higher contact rate by 19 points. Now it’s 2016, and they’ve both cleared 300 trips to the plate. Baez has been the better hitter. And so much more improbably, Baez has made more frequent contact. I’ll be damned. This is a hell of a thing that we watch.
