The comparative minor league stats of Evan White, the 17th pick of the 2017 draft out of college, and Triston Casas, the 26th pick of the 2018 draft out of high school:
EW 256 G, 1106 PA, .289/.357/.472/.829
TC 279 G, 1188 PA, .267/.373/.482/.854
Of course, the first basemen played in different minor league environments. White posted a wRC+, is adjusted for environment, of 132 in 400 plate appearances as a 23-year-old at Double A while Casas posted a wRC+ of 142 in 329 plate appearances as a 21-year-old at Double A.
Skipping Triple A, White made his MLB debut at 24 years, 89 days, while Casas is now at 22 years, 225 days.
Casas should be able to exceed the wRC+ of 52 that White has posted in 306 MLB plate appearances but fans should be prepared for a wide range of outcomes.
