Juan Soto Is Already Making History

Juan Soto is 19 years old and has hit 19 home runs this season. Of those 19 dingers, 14 happened before Soto reached the majors, but two of the MLB homers were hit last night. Through 76 plate appearances, Soto is putting up a Mike Trout-like .344/.447/.641 slash line good for a 192 wRC+ and an intriguing nickname. Hitting so well for a month is great, but it isn’t out of this world. So far this season, there have been 12 players who have put up a monthly split worth a 190 wRC+ or higher. That list includes names like Trout, Mookie Betts, Jose Ramirez, Francisco Lindor, and Manny Machado, but it also includes names like Daniel Robertson, Christian Villanueva, Brandon Crawford, and Scooter Gennett. What that hot start has done is changed Soto’s outlook both for this season and his career.

Soto has already drastically changed his projections for the year. Here are the top 30 hitters in baseball going forward according to our Depth Chart projections.

The projections say that at 19 years old, Juan Soto is one of the top 15 hitters in the game. The list above is an impressive one. Look at some of the names after Soto: Jose Ramirez, Carlos Correa, Jose Altuve. These are the very best hitters in baseball, and Soto looks to be their peer. Soto rose so quickly in part because of how little time he spent in the minors. As Eric Longenhagen wrote when Soto was called up, in recent history, only Alex Rodriguez had less experience in the minors than Soto. An injury last season kept his game log to a minimum, and that meant he was a bit underrated as a prospect entering the season. He was ranked No. 45 here at FanGraphs, and no major service put him among the top-20 prospects in baseball.

The recent update to the top prospects list here put Soto at No. 9, but he seems unlikely to make the list next season as he exhausts his rookie eligibility in the coming months. It’s difficult to understate how rare Soto’s performance is thus far, as his presence alone in the majors makes him a historical oddity. When Ronald Acuña was called up at just 20 years old earlier this season, Jay Jaffe conducted an analysis on debuts and the Hall of Fame. He found that of the 238 retired players to take a single plate appearance in the majors at 19 years old, 25 made the Hall of Fame, a roughly one-in-ten shot. Jaffe went a bit further and found that only 59 players in history took 100 plate appearances at Soto’s age, and of the 54 retired players, 13 went on to become Hall of Famers.

To try and put Soto’s season in context, I went back to 1905 and looked for players with at least 50 plate appearances at 19 years old or below. Soto already appears on the first page of the WAR leaderboards.

Of the 12 retired players above Soto, six are Hall of Famers. Three of the five players directly behind him are Hall of Famers, and the sixth player is Mike Trout. Also of interest, seven players have put up six-win seasons at age 20, and the only one not in the list above is Ted Williams. That list features nine of the best 13 age-20 seasons in history. Soto only has 76 plate appearances so far, but he’s also not done yet. For fun, let’s add two potential Sotos to the list above. One hypothetical Soto is completely unrealistic, but it shows what he would do with another 300 or so plate appearances if he kept up his torrid pace. The other version is more realistic, showing Soto’s rest-of-season projections combined with what he’s done so far.

Juan Soto is currently projected to have the sixth-best season by a 19-year-old since 1905 (and yes, I cherry-picked the year to get Ty Cobb in there). Of the six players to hit two wins in a season at Soto’s age, four are already in the Hall of Fame, a fifth is his teammate Bryce Harper, and the sixth, Edgar Renteria, put up 35 WAR in an underrated career. Refining the list a bit, here are the seasons of at least 300 plate appearances and a wRC+ of 100, a list Soto will crack after a couple-hundred plate appearances and a wRC+ above 70 the rest of the way.

Juan Soto’s season is special just because he made it to the major leagues. His season is spectacular due to his performance so far, and if history is any indication, he’s about to have a monstrous career.3
