Projecting Yoan Moncada
After they shipped Todd Frazier to the Yankees in exchange for prospects earlier this week, the White Sox replaced him on their roster with Yoan Moncada. Moncada was hitting a healthy .282/.377/.447 at Triple-A, highlighted by his 12 homers and 17 steals. He hits for average, hits for power, steals bases, and even draws walks. Very few players can hit like Moncada does while also providing value in the field and on the bases. That’s why he was a fixture at the top of midseason prospect lists this summer. Baseball America and Baseball Prospectus both ranked him No. 1, while Keith Law put him at No. 13.
But for all his strengths, Moncada has some weaknesses that we shouldn’t overlook. Most notably, he strikes out a bunch. Moncada’s struck out in over 28% of his trips to the plate this year. Though it’s been somewhat hidden by his high batting averages, Moncada has had a lot of trouble making contact against minor-league pitchers. This suggests he’ll have even more trouble doing so in the big leagues, which is exactly what happened in Boston last September when he struck out 12 times in 20 plate appearances.
There’s also the matter of Moncada’s defense. He’s primarily played second base since emigrating from Cuba, and the prognosis for minor-league second basemen isn’t great. The fact that he’s already been deemed “not a shortstop” is a knock against him in KATOH’s eyes. Furthermore, his defensive metrics at second base aren’t great. He’s been right around average there by Clay Davenport’s fielding data this year and was several ticks worse than average last year. This suggests he may not be a defensive asset in the infield.
