In my head, and I don't know if it is real, but Luis Gonzalez seems to be a reasonable analog for Steele Walker. and last year at WS, Gonzalez hit .313/.376/.504. Walker is currently at .267/.341/.419. That was in 62 games for Gonzalez and 72 currently for Walker. Gonzalez had hit more doubles and triples, Walker has 1 more HR. Gonzalez had a 27/46 BB/K ratio and Walker's is 28/47. Their numbers are pretty similar. And a lot of people (myself included) were pretty optimistic about Gonzalez, but the adjustment to AA has tempered that a little bit.
Now, I am not a scout, and honestly haven't seen more than 25 ABs from either guy, so maybe this comp is way off. They just seem like similar type players to me. Though if Walker has been battling a core injury all year, that certainly would have an impact.
I say this, just to point out how difficult the jump from A+ to AA can be.
For reference, I didn't vote, because I feel like the 2 guys are pretty close, and I'm hopeful that out of the two (3 with Gonzalez) the Sox get a RF.
