Juan Soto rode his hot start all the way from A-ball to the big leagues. The wunderkind for the Nationals exploded onto the MLB scene this past Monday, slugging a three-run home run in his first start in the majors. The 19-year-old has had a transcendent minor league season; Soto slashed .362/.462/.757 in 39 games across three levels. He bashed 14 home runs, drove home a staggering 52 runs, and tallied more walks (29) than strikeouts (28) during that span. Injuries to Adam Eaton and Howie Kendrick, along with fellow highly touted prospect Victor Robles, allowed Soto to zoom to the bigs. If he continues to rake, it will be awfully difficult to send him back to the minors.
Let's take a look at some other notable prospects in this edition of the Minor League Barometer.
Alex Reyes, P, STL – Reyes missed all of last season due to Tommy John surgery, but the 23-year-old remains one of the top pitching prospects in the game, and his rehabilitation starts have gone swimmingly. In three starts at three different levels, Reyes has yet to allow a run while posting a superior 31:6 K:BB in 16 innings. Though the sample size is small, the opposition is hitting a paltry .115 against him. Though the Cards will certainly be cautious with their prized phenom, particularly following Tommy John surgery, it would not be unexpected if Reyes joined the St. Louis rotation this summer.
Jon Duplantier, P, ARI –
