There's no easy solution. The original contingency plan at first was Wilmer Flores, but he's on the DL and was not hitting when he was healthy. I still have to think he'll get the primary opportunity come Friday, and hopefully he'll deliver with the bat and render the rest of the discussion moot. Asking Walker or Conforto or Wright to learn an entirely new position on the fly mid-season is risky. Of the three, Walker makes the most sense because of Dilson Herrera (although Herrera's bat has gone cold this past week). I also think you'll have much better luck getting an infielder to learn first base quickly rather than an outfielder. I keep going back to why they waited so long to part with Tejada this offseason. The could have gotten David Freese the week before they released Tejada. Freese hasn't really played first before either, but (a) he'd have had the whole of spring training to learn it and ( unlike Campbell, he belongs on a major league roster. On the trade front, the Cardinals have Brandon Moss and Matt Adams and don't need both of them. I'm not sure what they'd want, and I wouldn't pull the trigger today, but I'd ask.
