OPS is still above 0.700. He has walks/walked a ton, always has power, and plays a fantastic 1B. I think he's here for the season, personally. What has happened is a prolonged slump since the away Jacksonville series. He was batting back to 0.224 at that point? Regardless, it will be interesting to see what happens in the second-half of the year. I think the Brewers see him as solid insurance should anything go wrong - batting average aside. Plus, he's absolutely loved by his teammates.
The issue at large, if we're being honest, is there simply aren't a lot of 1B options in the system. Perhaps, the young man having the most promising year at 1B (in terms of upside and development) has been shelved with injury for over a month - Ernesto Martinez. Tyler White has gotten hot again here in the short-term and profiles as your classic bench 1B/DH if the need arises. Thomas Dillard is a likable guy and another walk machine - he essentially protoypes as a strictly Vogelbach-type of player in that he's shorter, stalkier etc. and will never give you plus defense though he is fine within his limitations. He leads the Southern League in walks and has gotten mildly hot at the plate recently - another 1B prospect who has hovered around 0.200 for most of the season with a similarly plus-0.700 OPS. Wes Clarke has filled in admirably over the course of the season and is turning into an interesting C/DH/1B option in the system. He's been a joy to watch though he is clearly limited athletically. However, he's just a very solid baseball player with, perhaps, the most supportive nuclear family fan-base I've ever seen.
All-in-all, though, we don't appear to have a stud in the wings. Perhaps, the club treats that situation like the Packers treated ILB for over a decade? I don't know. I like all these guys, however, and have to believe the Brewers see enough supportive qualities in the collective to fill-in if for some reason injuries really ran rampant.
