Helena's mediocre season is damping some enthusiasm, but Walla is having himself a pretty solid season as a 20 year old in the Pioneer league. I wouldn't get excited, but his average, power, and discipline have all improved quite a bit. I think he might be my sleeper for next year, if he starts to harness more of that BP power he seems to have all the other batting skills seem in line for him to explode as a prospect, so that's kind of fun.
