No position player in the Minnesota Twins organization has been less appreciated in the last few weeks/months than Max Kepler. After a hot start to the 2022 season, the German outfielder saw his offensive productivity dramatically decrease in the second half of the season, mainly after suffering a fracture in his right pinky toe in mid-July.
He’s now the guy most Twins fans want the team to get rid of, but since his trade value isn’t very high right now, Minnesota might have no other option but to stick with him for now. Which brings me to the question: can Kepler get back on track and help the Twins' offense in 2023? I think there are reasons to believe so.
Kepler’s regression isn’t an individual outcome
Kepler had arguably the worst offensive performance of his career in 2022. With a career-worst .666 OPS. It was the first time in his big-league career that it went below .719 for a season. But he was hardly the only Twin to see his offensive productivity plummet in the last three years.
In three seasons under former hitting coach James Rowson (2017-2019), Minnesota had an elite offense, ranking among the top five or six best offenses in baseball in a number of offensive metrics: fifth in baseball in wRC+ (105), sixth in OPS (.775), fifth in SLG (.445), sixth in wOBA (.330), and fifth in ISO (.185). In the following three seasons after the New York native departed the organization, the Twins failed to rank at the league’s top ten in most of those same metrics.
Kepler experienced his offensive peak with Rowson as the Twins' hitting coach with back-to-back above-average seasons (wRC+ above 100). Since his departure, he regressed into a slightly below-average hitter, similar to the one he was when Rowson joined the club.
The past couple of seasons have been rough for the entirety of Minnesota’s offense, which possibly had more downs than ups. David Popkins took over as the team’s hitting coach after the 2021 season, making 2022 a season of getting used to a whole new regime. Kepler struggled overall, but that doesn’t mean he did everything wrong. Here’s why.
Kepler might be a few tweaks away from getting back on track
When browsing through Kepler’s Baseball Savant page, you get smacked in the face with his surprisingly good 2022 Percentile Rankings. What conclusions can we draw from this?
- He failed to get good quality, hard contact last season. While his average exit velocity (89.1 MPH), Barrel% (7.1), and HardHit% (39.9) are still slightly above league average, last year’s percentile rankings in those metrics are some of the worst in his career. Curiously, though, all three of them were worse in 2020, the last season in which Kepler finished with an above-average wRC+.
- He might never have been more disciplined at the plate than last season. Despite his struggles with hitting for power, Kepler posted a career-best 14.8% K%, making him better than 88% of all hitters in baseball. Also, he had an 11% BB%, well above league average (8.4%), making it the third consecutive season with an 11% or better walk rate. He draws more walks than 84% of all major-league hitters. His Whiff% (19.9) and Chase% (23.5) are also among the league’s best.
- His expected stats might indicate some improvement is coming. Expected statistics are fun to look at. They aren’t necessarily predictive, but they can tell you how well a player is doing things compared to the league-wide execution. For instance, Kepler’s expected stats trended upward in the first two seasons of Rowson with the Twins, resulting in a great 2019 season for him. Then, they started trending downward for the following two seasons, resulting in a poor overall performance in 2022. But as you can see in the image above, his xwOBA, xBA, and xSLG had some of the best percentile rankings of his career.
So what does Kepler need to do to improve in 2023? And will he?
When you hit rock bottom, there’s nowhere to go but up. Assuming 2022 was Kepler’s rock bottom offensively, it is logical to believe that he’s bound for some improvement, especially after finding out he’s in an upward trend in his expected stats. This is not just a logical conclusion from myself: several projections also believe Kepler will be a better hitter in 2023. On his FanGraphs page, you can see how every pre-season projection (the green rows) expects him to reach at least 103 wRC+ this year, with the most optimistic one saying he could reach 113 wRC+.
But how can that happen?
Well, the good news is that we know what he needs to work on this offseason and preseason: putting the ball in the air. Kepler’s decreased productivity on offense goes hand in hand with his reduced launch angle and increased ground ball rate. In 2020, his last season with a wRC+ above 100, his launch angle average was 22.2, a career-best. In 2022, however, that came down to 11.2, the smallest one since his rookie season. His ground ball rate also increased significantly in that span, going from 32.4% in 2020 to 45.7% last year.
If Kepler gets back on track, what does that mean for the Twins?
Kepler is one of MLB’s best defensive outfielders, ranking sixth in the majors in OAA (11) and ninth in DRS (9). Most of his 2.0 fWAR in 2022 was thanks to his defensive contributions. If he can improve the aspects mentioned in the previous paragraph and regain some confidence offensively, he can become an important cog in the Twins' offense. But does that mean he’ll stick around long? Not necessarily.
The Luis Arraez trade proved Minnesota’s front office is willing even to part ways with a fan-favorite in order to improve their roster. In the eyes of Twins fans, Kepler’s appreciation was never close to that of Arráez’s, so if Kepler actually manages to get back on track offensively, he might become a valuable trade piece. With outfielders such as Trevor Larnach, Matt Wallner, and Mark Contreras having already made their big-league debut, it’s hard to imagine Kepler, who’s in the final year of his contract, not getting dealt soon, provided he regains some of his trade value.
