I don't think it's a good sign for the system as a whole when so many current draftees are ranking this high. These kids barely got to play this year and it seems as if they are making the list because they haven't had a chance to shows the flaws in their game.
I will plant the Adam Hall flag here - probably on my own island - well as a comp to Vavra - not necessarily at 13.
Both Hall and Vavra played in the South Atlantic League last year.
Vavra had extreme home away splits and by extreme I mean Home 400/484/640/1124 and AWAY 224/320/316/636.
Hall's overall numbers trail Vavra due to that extreme split, but in (IMO) the most legitimate comp between the two - Hall outhit Vavra on the road with a respectable 291/360/369/729. League average numbers for the South Atlantic League last year were 239/316/362/677 which Vavra's road numbers trail. Vavra's road numbers also trailed those of the promoted 2019 draft picks Johnny Rizer and Toby Welk in the Sally League in 2019 - prospects I don't think we will see anywhere near here.
As Tony mentioned, included in Vavra's numbers are superior BB/K numbers which were 62/62 in 2019 with similar home/away splits. Hall did walk in about 9% of his PAs, but struck out much more often in 117 times - nearly a quarter of his PAs.
I believe Hall has a better middle infield defensive profile with a chance, albeit a low one, to stick at SS but capable of playing a competent major league 2B IMO.
A final important factor to me is that Hall is two years younger than Vavra and played about one year younger than the Sally League average in 2019 while Vavra was a year older than league average.
Tony has the inside word here and the Os had to like something in Vavra to take him in trade so I will prepare in advance to eat future crow when I say I prefer Hall to Vavra.
