A Flimsy Excuse To Write About Juan Soto
Of course, calling Soto a playoff superstar sells him short. His genius isn’t limited to the postseason. He’s simply one of the top five players in baseball, full stop; his combination of unparalleled batting eye, tremendous bat control, and startling power are exciting enough, and that’s before considering the fact that he didn’t turn 22 until this October. Quite simply, he’s a huge part of the future of the game. Heck, ZiPS comped him to literally Ted Williams earlier this offseason.
Because of that, it’s easy to forget about Washington’s 2020. Before the season, they were defending champions, and then BAM, it was over. Weird! But this is an article about Soto, and Soto didn’t fade like the rest of the DC nine. He hit, and hit, and hit some more, to the tune of a Bonds-looking .351/.490/.695 slash line. It’s hard to think about that line, because what in the world does a .490 on-base percentage look like? .695 is a middle infielder’s OPS, not a slugging percentage. It beggars belief.
Perhaps my favorite part of Soto’s game is how it feels like you can think along with him. As a rookie, he was of course transcendent. He did it with great talent but also one simple trick: when people threw him offspeed and breaking pitches, he simply didn’t swing. That’s impressive, particularly at age 19, and it suggests room for improvement: as it turns out, there are some offspeed pitches you should swing at.
In 2019, Soto stepped out of his comfort zone a bit. He upped his swing rate across the board. Here, consider it in this oversimplified grid presentation:
Year | Zone Fastball | OZ Fastball | Zone Breaking | OZ Breaking | Zone Offspeed | OZ Offspeed |
---|---|---|---|---|---|---|
2018 | 66.7% | 18.2% | 45.4% | 14.4% | 68.3% | 25.4% |
2019 | 65.5% | 21.7% | 64.4% | 18.2% | 75.0% | 19.5% |
The main change Soto made was swinging more at breaking pitches of all stripes. Most of it was in the zone — Soto is outrageous, remember? — but he also chased a few more, which is the cost of swinging more often overall. You couldn’t see it in his stats. In 2018, Soto struck out 20% of the time and walked 16% of the time. In 2019, those numbers were nearly unchanged — 20% and 16.4%, respectively. Under the hood, however, he was doing it differently.
In 2018, Soto was downright disdainful of pitches outside the strike zone until there were two strikes, swinging at only 11.2% of them. That number ticked up to 14.5% in 2019, largely on what I’ll call pitcher’s pitches: pitches that are in Baseball Savant’s “Shadow Zone,” the borders of the strike zone, but still out of the zone. Think of a fastball just above the zone or a slider that doesn’t quite clip the outside corner. On those pitches, Soto’s swing rate increased from 20% to 26.8%.
Those changes came with a benefit. By thinking swing more often, Soto also pulled the trigger more often on pitches down the heart of the plate. In 2018, he swung at 60.2% of pitches down the middle (in non-two-strike counts). In 2019, that ticked up to 68%. In other words, he was looking to do damage, hunting pitches he could drive. If that came with a few extra swings at suboptimal pitches, so be it.
Fast forward to 2020, and Soto made another change. Let’s start again with that generic in-or-out-of-zone depiction:
Year | Zone Fastball | OZ Fastball | Zone Breaking | OZ Breaking | Zone Offspeed | OZ Offspeed |
---|---|---|---|---|---|---|
2018 | 66.7% | 18.2% | 45.4% | 14.4% | 68.3% | 25.4% |
2019 | 65.5% | 21.7% | 64.4% | 18.2% | 75.0% | 19.5% |
2020 | 60.8% | 18.1% | 58.9% | 13.0% | 65.7% | 13.0% |
Broad strokes here: Soto throttled down a bit on fastballs, kept most of his aggression on in-zone breaking balls, and stopped swinging at secondary pitches outside the zone altogether. For someone who mashes fastballs as much as Soto — he’s finished in the 94th percentile or higher in production on counts ending in fastballs in each of his three major league seasons — it’s not the end of the world to swing slightly less often at them, because it hardly gives pitchers license to come after you with fastballs. Attack Soto with fastballs? He could swing far less and that would still be a bad idea.
Meanwhile, swinging a little less often in good spots helped him swing far less often in bad spots. Look back up at the table. Those swing rates on secondaries that missed the zone are absurd. Here’s a list of every player who swung at 13% or fewer of the pitches they saw that matched those criteria:
Player | Breaking Swing% | Offspeed Swing% | Combined Swing% |
---|---|---|---|
Juan Soto | 13.0% | 13.0% | 13.0% |
Yeah, look, sorry. It’s a stupid table, that’s on me. I just want you to appreciate the mastery on display when Soto steps to the plate. Meanwhile, he’s middle of the pack when the pitches cross the plate, swinging at 61.8% of them against a league average of 66.4%.
Again, we’re just scratching the surface of swing/take decisions by crudely separating pitches in and outside the strike zone. Recall those two categories earlier — pitcher’s pitches and ones right down the heart of the plate. On pitchers’ pitches with less than two strikes, Soto swung only 19.5% of the time this year, the lowest rate of his career. His pitch recognition is so good, and his confidence in his ability to hit with two strikes so high, that he lets those pitches go by even if they might be called a strike. That was the seventh-lowest swing rate on those tough pitches, and the hitters in front of him are pretty good too:
Batter | Swings | Pitches | Swing Rate |
---|---|---|---|
Tommy La Stella | 27 | 149 | 18.1% |
Trent Grisham | 26 | 143 | 18.2% |
Alex Bregman | 21 | 114 | 18.4% |
Clint Frazier | 22 | 117 | 18.8% |
Mark Canha | 27 | 141 | 19.1% |
Mike Trout | 23 | 118 | 19.5% |
Juan Soto | 26 | 133 | 19.5% |
Carlos Santana | 34 | 166 | 20.5% |
Cavan Biggio | 35 | 164 | 21.3% |
Max Muncy | 34 | 155 | 21.9% |
Meanwhile, he finished near average on his swings on pitches over the heart of the plate, at 64%. How many players swung at fewer pitchers’ pitches and more hitters’ pitches than Soto? None, naturally. He’s otherworldly.
All of these words, these in-zones and out-of-zones and pitchers’ pitches and hitters’ pitches and whatnot, are a complicated way of talking about a simple thing. Right now, Juan Soto has the best pitch recognition in the major leagues. He knows what to swing at and what to spit on in a way that no one has since peak Joey Votto. Oh yeah — he’s making contact more often, too. In 2018, Soto had a weakness of sorts. Even when he swung at in-zone breaking balls, he frequently came up empty. His 23.3% whiff rate there was worse than league average, and even when he did make contact, he didn’t hit it hard; he had no barrels and a 19.4% hard hit rate. He was even worse on changeups and splitters; a 27.3% whiff rate and 10% hard hit rate are both pretty dire.
This year, that all changed. In an admittedly small sample, he simply stopped whiffing. He’s down to a 16.1% whiff rate on breakers and a 15.2% whiff rate on offspeed pitches. He’s hitting both types hard more frequently — roughly 30% on each. His barrel rate on in-zone breaking balls was a ludicrous 16.1% in 2020, for goodness sake. That’s the same as Ronald Acuna Jr.‘s barrel rate on all batted balls, fastballs included. Good luck pitching to that!
In fact, I’ve been talking too much. Baseball Savant said it better. Want to see some red numbers? Let’s look at some red numbers:
Is that good? I think it’s good.
You’ll notice that I haven’t talked about any actual results in this article since referencing Soto’s eye-popping slash line. That’s because what’s most impressive about him isn’t his 200 wRC+ — though that’s certainly impressive — or his .344 ISO. It isn’t the fact that he batted .350 and walked more than he struck out. Those are all amazing, all jaw-dropping, but what stands out most to me is the purity of his process.
That Ted Williams comparison up above wasn’t an idle one. I wasn’t alive to see Williams play, but his distillation of hitting into a science feels exactly like what Soto is now doing. He’s grinding away inefficiencies, replacing the holes in his game with ever more strengths. His 2018 form was a caricature of a slugger with a good eye: he punished fastballs and ignored breaking balls. In 2019, he got more proactive against everything. Now, he’s synthesized the two to create an unsolvable puzzle for opposing pitchers.
Do I think he’ll improve on his 2020 next year? Nope! He had a freaking 200 wRC+. He slugged .695. That’s not a median forecast for anyone this side of peak Barry Bonds. What I do think is that I’ll enjoy watching Soto more than any other hitter in baseball. I don’t know what he’ll do next, but I love the feeling of wonder I get when I watch him at the plate, shuffling and pondering, deciding what weakness to attack next.
I can honestly say that I don’t get that feeling from anyone else playing right now, which is why I came up with this contrived article. Watching Soto hit is a pleasure. Writing about him is just as much fun, and I’m nothing if not self-serving. So enjoy it! I know I did.
