During the 2017 campaign, Kepler posted a career best .737 OPS. It was a very slight improvement over his 2016 season, and the thought was that he could be a prime candidate for a breakout in the year ahead. Through 96 games this season, he owns just a .731 OPS and hasn't taken the step forward that was imagined for him. That's the bad news. The good news is this story is still being written.
On the surface, it seems that Kepler is simply repeating the same level of production he's had over the course of his big league career. Diving a bit deeper however, we see some narratives that suggest much more could be coming.
Before diving into any underlying stats, Kepler's slash line this year is interesting in its own right. His .226 batting average is a career worst, but the .314 OBP is a career best. With 44 walks already, he's going to easily set a career high in that category. The German born outfielder also already has 13 longballs to his credit, and reaching 20 for the first time in his career seems like a foregone conclusion. Striking out less, walking more, and leaving the yard at a higher rate are all avenues for success.
Unquestionably, the biggest development for Kepler has been his regained ability to hit left-handed pitching. After posting a .453 OPS against southpaws last season, he now owns an .831 OPS against those same pitchers in the current campaign. Oddly he's fallen off a bit against righties, owning just a .689 OPS, but eight of his 13 homers have come against opposite armed pitchers. Being able to even out the splits, or more desirably mash righties again, would significantly raise Kepler's water level across the board.
Looking at the quality of balls Max is putting in play we can see signs of a potential breakthrough ready to happen. Although his average sits at .226 on the year, Kepler is generating an unreasonably low .239 BABIP. That mark is significantly below the .276 tally from 2017, and given the career high 38.6 hard hit rate, there's plenty of room for growth.
In previous interviews Kepler has turned his nose at the launch angle revolution. He's actually been goal in saying that it was his goal to put the ball on the ground. By now we know that isn't a viable path to success in the big leagues, and Kepler's numbers have begun to turn away from that. In 2018 he owns a career low 37.9% ground ball rate, and a 45.5% fly ball rate. If there's missed opportunity here, it comes in the form of a HR/FB ratio sitting at 10.3%. Right now Kepler may be getting too far under the ball, and staying within career norms at a 16.6% line drive rate, he's got a bit of room to flatten out the balls he's elevating.
Earlier I touched on the heightened level of plate discipline that Kepler has shown this season, and that's obviously a direct results of his efforts as well. In 2018 he's dropped his swinging strike rate all the way down to 7.4%. That new number is nearly a 2% decrease from a season ago, and a full percent lower than his career average. On top of missing the ball less, he's also chasing pitches out of the zone at a career low 24.9%. In short, it adds up to the perfect storm.
Right now the sum of Kepler's parts has plenty of room for growth. What's a very encouraging sign is that he's hardly defined as the player with a .226 batting average. Continuing to sting the ball while working to optimize his launch angle should only help to drive the BABIP north. As he's able to settle in more against righties, the damage only has an opportunity to become universal. There's been a lot asked of Kepler in a season where Byron Buxton has been nonexistent, but the growth opportunity for a player that's just 25 can do wonders down the road.
No matter what it currently seems like, the best is yet to come for Max Kepler and the Minnesota Twins.
