Only a couple of months ago, first base seemed set for the next decade or so. The only question was when Jonathan Singleton would take over and begin his run at the corner that has produced some of the Astros' most enduring names like Bagwell and Berkman, and even Watson and Davis (as in Glen). Now -- at least for the foreseeable future -- the job seems to be Brett Wallace's to lose...again. While it may be considered an open competition, there is very little suspense at first base as the Astros' prospective list is short.
