Rafael Devers Is Still a Work In Progress
Generally speaking, doing more of one thing means doing less of another. A positive development can come at the expense of some other attribute and unintended consequences can make that positive thing decidedly less so. It’s one thing to strike out less often. Putting more balls in play provides the potential for positive outcomes. It’s another thing to strike out less often and walk more often. Doing those things in concert can have a great effect on getting on base and not making outs, which is almost always the point of every plate appearance from a hitter’s perspective. Sometimes, doing both doesn’t lead to positive results, and Rafael Devers found that out the first month of the season. Instead of going back, though, he’s moved forward and is hitting better than ever.
The 2018 season wasn’t a great one for Devers statistically. He wasn’t terrible, posting a slightly lower than average 8% walk rate and 24% strikeout rate, as well as better than average power with a .193 ISO, but a .281 BABIP meant a .240 batting average a sub-.300 on-base percentage and a below-average 90 wRC+. In his 2017 debut, Devers’ numbers were mostly the same, but a .342 BABIP meant a 110 wRC+. The Statcast data indicates that the difference between 2017 and 2018 was mostly luck, and Devers’ batted ball profile in terms of ground balls, line drives, and pulled balls were all pretty similar in 2017 and 2018, giving credence to Devers being a bit lucky in 2017, with 2018 his natural level if all else remained the same.
Devers wasn’t content with remaining the same, so he spent the offseason working on his weight and now focuses more on not striking out and incorporating video of pitchers in his preparation. While all those changes are admirable, they failed to make a difference the first month of the season. On April 25, Devers had completed 101 of his 201 plate appearances this season. True to his word, Devers struck out a lot less, lowering his strikeout rate down to 16% on the season and saw his walk rate rise to 12%. Devers also saw his BABIP rise to .338 so the lowered strikeouts and increased walks caused his batting average to stand at a healthy .276 with a very good .370 OBP. Unfortunately, Devers had yet to hit a home run and only had six doubles, leaving his ISO at a meager .069 and his wRC+ right at 90, the same as where it was the previous season.
