I'd like to know where you got those stats from because Walker had 560 PA in 2015 so your trying to say he accrued 388 PA against Top 20 MiLB talent leaving 172 PA against non Top 20 talent? No way, MiLB has a list of every pitcher he faced this year and what you state is not feasible. These are NOT the same arms that he will face in the future. Its true that he'll face some of the same arms in the MLB but the majority of players in AA don't make it to the big leagues. The further and further he climbs up the ladder, the harder and harder the level of competition gets. Walker has shown improvement the further he's gone, he's also shown regression. Walker has learned to walk more and that is seen in his BB% the past three seasons 5.6%, 7.9%, 9.1%. Yet his K rate keeps getting worse 20.8%, 28.2%, 34.8%. In an abbreviated season in the AFL (86 PA) Walker played against the "best of the best" his K rate was 9.3% and BB rate 40.7%. Terry Ryan said it himself, strikeout rates usually tend not to go down the further one proceeds up levels. I like AB, he's a great kid and his power is awesome but his inability to hit for contact and lay off sliders is becoming more and more of a problem the further he goes up in the levels. I think he can succeed but his best case scenario is Chris Carter, his worse case is Pedro Cerrano. Maybe Walker needs Joboo...
