The Complicated Mix That’s Hurting Juan Soto
In no world is Juan Soto is having a bad year. Through games played on Saturday, he has more walks than strikeouts, a 128 wRC+, and a .272/.404/.426 triple slash in 240 plate appearances. He’s been worth 1.6 WAR in 58 games, thanks at least in part due to improved defense; ZiPS projects him to add another 3.5 wins the rest of the way, which would result in a career-high 5.1 WAR. Even at his current pace of 4.5 WAR, Soto would end the season as one of the more valuable players in baseball.
By his standards, however, Soto is actually having a bit of a down year. That 128 wRC+ I mentioned? That is just above his worst mark in any 58-game stretch (127) of his entire career. It still represents great production in a vacuum, and the fact that his worst wRC+ still is 127 is just another way to underscore his greatness. But at the same time, it still leaves us with a lot of questions, none more important than this: Why has Soto seen such a notable decrease in performance?
The answer might seem somewhat simple: He’s hitting far too many groundballs. Soto currently has a 55.3% groundball rate, seventh-highest in the majors. The fact that he’s still posting a 128 wRC+ in spite of that is borderline absurd; of the 30 qualified hitters with at least a 48% groundball rate, he has the highest wRC+, a testament to his phenomenal plate discipline and frequency of hard contact.
As a result of all of these grounders, Soto is embarking on Vladimir Guerrero Jr.’s 2020 journey. But while Vlad Jr. is currently elevating and celebrating this year, Soto is grounding and outing. Bad attempt at a rhyme aside, his groundballs mostly turn into outs. The ones that aren’t outs? They are singles, and they the reason why he has experienced a personal power outage. In his last 50 games, he has a .137 ISO, another career low for a sample that large.
