Hummel's got a cannon for an arm. From that 2019 article that boosted him to my vote for #1: "During Spring Training in 2018, Joe Ayrault — my manager in Carolina the previous year — told me that he wanted to try me in the outfield a little so that I could get more at-bats during the year. Outfield wasn’t totally new to me, I had played a little in college. I was in left field the next day and the first ball that came to me, I hosed a runner at the plate." https://www.brewcrewball.com/2019/11/25/20982116/milwaukee-brewers-cooper-hummel-prospect-interview If there had been a minor-league season in 2020, I think Hummel would be up, probably in that Vogelbach role, and I think he'd probably have had some time at 1B in AAA. He got a runner great but no where in that article does it state he has a good or even a cannon for an arm. I don't see any scouting reports that back up what you are claiming that he has a good arm or even a cannon for an arm. Hosing a player at the plate doesn't really mean much if it was Jonny Estrada running the bases you don't need a strong arm to throw him out at the plate. He was also in LF doing this so I am going to go with the coaches here and say he is a LF and won't see much if any time in RF and that is probably because of his arm is not strong enough to play there. With him getting very little to no time at 1B I don't believe the Brewers see him as a 1B and thus in the Brewers eyes he is a LF/DH only.
