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.
Double plays is where the poor arm comes in.
This is an interesting part of the list every year because it's where Tony has to mix in 40-45 FV guys with really young guys with huge risk. I'm sure there's a system, but I definitely don't have one. Lol.
As for Vavra and even Diaz, it's worth noting that there's some upside there as the ceiling is a 50 FV guy. Having a few guys in the upper minors with a 50 FV is a good thing. They won't all pan out, but if one or two of these types of guys pans out to that 50 FV then you have a real asset on your hands.
The same is true with pitchers, where we have a lot of guys who kind of fit a Vavra-like profile. Means was one of them, and look what happened. There's value here for sure.
I would think the poor arm won't factor in that regularly at 2B where it would prevent him from being an everyday option there, particularly if the bat plays.
Other than throws home or to third, where would a poor arm as a 2B come into play? The answer may be during large shifts, but could you leave him in the regular 2B spot and slide the SS or 3B into shallow RF for the exaggerated shifts? The main issue then would be shifts on right-handed hitters...
