Chicago Cubs: Kyle Schwarber’s discipline, leather helping resurgence
The resurgence of Kyle Schwarber has been a boost to the Chicago Cubs’ struggling offense. Aside from his bat, improved plate discipline and a renewed sense on defense have helped drive his success.
Last year when the Chicago Cubs sent Kyle Schwarber to Triple-A Iowa, things didn’t look good.
He carried a .171/.295/.378 slash line when that decision came down the pipeline from the brass. A World Series legend on the North Side less than a year prior, reduced to a head-scratching struggling outfielder. Despite it all, the Cubs believed (and still do) the former first-rounder had barely scratched the ceiling of what he was capable of.
Despite a marked offense improvement in the second half, Schwarber finished the year with a disappointing .211/.315/.467 line. The main bright spot? His career-high 30 home runs.
This past offseason, Schwarber was the talk of the town. He lost 30 pounds in hopes of rebounding and increasing his production at the dish. So far, its all systems go for the young slugger.
Schwarber, in his first 30 games of the season, through 103 plate-appearances, slashed .270/.369/.562 with seven home runs and 17 RBI. He is currently sitting on a .391 wOBA and 149 wRC+. With every aspect of his game seemingly improved, two unique aspects of his game stand out: plate discipline and his fielding.
Discipline drives success
For Kyle Schwarber, one aspect of his game which has been driving early season success has been his plate discipline.
So far this season, Schwarber is swinging at fewer pitches outside of the strike zone, more pitches inside the strike zone and is seeing his overall contact numbers increase because of it.

According to Fangraphs, Schwarber, so far this season, has swung at 24.6 percent of pitches outside the zone. It is down from 28.2 percent in 2017. That being said, his contact rate for pitches outside the zone has increased from last season. What does this mean? Schwarber is decidedly smarter about what pitches he attacks outside the zone.
Overall, his contact rate has risen from 72.4 percent in 2017 to 75.1 percent this year. Schwarber is making contact with three-quarters of all pitches he sees.
Continuing the trend, Schwarber’s strikeout rate has dropped like a rock. Last year, he struck out roughly one of every three at-bats (31 percent). This year, he’s down nearly seven percent – to 23.3 percent. His walk rate? Yep, that’s up, too. He’s walking in 13.6 percent of his trips to the plate – up from 12.1 percent a year ago.
To add to how high his discipline has been so far this season, Schwarber has decreased his swings and misses from 12.2 percent to just over 10 percent. Understandably, it is a month into the season. However Kyle Schwarber continues to be smart at the plate, and it continues to reap the rewards.
Rejuvenation in left field
Diving into more analytically robust statistics, Kyle Schwarber has had a great start to his season in left field, despite some strange misplays which have come his way.
One stat, known as Revised Zone Rating, according to Fangraphs, takes measure of the proportion of balls hit into a fielders zone which he successfully coverts to an out. As the game has transformed with better measured stats such as Ultimate Zone Rating, this is a good way to introduce someone to analytical fielding statistics.
For Schwarber, his RZR his sitting at an above-excellent .957 through his first 174 innings in left field. He also has both a positive UZR and UZR/150 this season, which measures Ultimate Zone Rating over 150 games played.
In terms of DRS, or Defensive Runs Saved, which is exactly what it sounds like, last season Schwarber posted a porous -9 DRS. So far this season, he has a +1 DRS. Smaller sample size in comparison, however it has been a huge improvement for all.

Moving forward
As it is just a little more than a month into the new season, it can be difficult to judge success based on a limited amount of opportunity. That being said, Kyle Schwarber has entirely found his groove so far, in all aspects of his game.
For Schwarber, the Cubs and the fans, it is nice to see him produce at a level we’ve come to expect since he debuted. Now, it’s about staying healthy and continuing to mash. Do that and the sky is the limit for Kyle Schwarber.
