Why not hype Royce Lewis as AL rookie of the year? Rookies with a full year (or nearly so) in the league have a certain advantage, but none of the familiar names have numbers approaching Royce. Royce is number one in average, slugging, HR/AB, RBI/AB, and OPS.
Rankings by OPS w 200 minimum AB:
Royce Lewis .302/.365/.545 202 AB 14 HR 50 RBI and .910 OPS
Tristan Casas (Bos) .263/.367/.490 429 AB 24 HR 65 RBI and .857 OPS
Zach Gelof (Oak) .268/.335/.516 213 AB 11 HR 25 RBI and .8
Random thought here. There's been a lot of buzz about the historically good rookie trio of Julien, Wallner, and Lewis, but I haven't seen anyone observe that this happened despite the Twins' farm system being fairly low-ranked coming into the season, and for the last couple of seasons for that matter.
