Where Did Ketel Marte’s Power Go?
I’m sure plenty of us would like to simply forget that 2020 ever happened. In this fictional world where a Men In Black neuralyzer is used to erase the memory of the last 12 months, Ketel Marte would be feeling pretty good about his previous season. 2019 was a big year for Marte. He posted a 150 wRC+ and accumulated 7.0 WAR, both easily career highs, and earned a fourth place finish in the NL MVP voting. With last year wiped clean, he’d be looking forward to building off his breakout in 2021 and establishing himself as a bonafide superstar. Instead, the memory of nearly 200 so-so plate appearances in 2020 comes flooding back and all sorts of questions about his true talent level begin to popup.
When compared to his performance prior to 2019, his 2020 season doesn’t seem all that out of place. His power output dropped back to where it was before his breakout, leading to very similar overall offensive contributions to his early career line.
Year | PA | K% | BB% | ISO | BABIP | wRC+ |
---|---|---|---|---|---|---|
2015-18 | 1548 | 15.7% | 8.1% | 0.126 | 0.302 | 92 |
2019 | 628 | 13.7% | 8.4% | 0.264 | 0.342 | 150 |
2020 | 195 | 10.8% | 3.6% | 0.122 | 0.311 | 94 |
Which season seems like the outlier when put into this context? Of course, it isn’t so easy as simply throwing out his 2019 and settling on a true offensive talent that falls somewhere around 5% below league average. Most of the projection systems think he’ll fall somewhere in between, with some but not all of his power returning.
Marte’s power surge in 2019 was driven by a significant increase in the number of hard hit balls he put in play in the air. He increased his average launch angle from 5.8 degrees in 2018 to 11.5 degrees in 2019. Along with making more authoritative contact more often, those hard hit balls were pulled more often, too. Every single adjustment he made resulted in greater damage when he put the ball in play. Read the rest of this entry »
