Pretty crazy how inflated AAA hitting stats are. Walker Jenkins' .785 OPS looks rough compared to the rest of this crew. I know it's not a popular take, but I wouldn't mind if we don't see him in the majors this year.
For even as hot as Wallner is, Roden still has 150 OPS points over him and is striking out a lot less often. Add in Wallner's defense which I doubt has gotten better, and I don't see why you'd take Wallner over Roden. I'm sure if called up Wallner would hit more HRs, but the Ks are always gonna be a problem.
Mendez is raking too, from what I've seen, I'm not convinced he is a major league caliber outfielder. It might be wise to give him reps at 1B over Sabato, who is hitting well too but still is very unlikely to be a major league caliber bat (he's gonna strikeout all the time). I'm interested to see Gonzalez splitting his reps evenly between LF, RF, and 1B, but he just hasn't hit well this year compared to what the rest of AAA hitters are doing even with his recent hot streak.
