I think Chang was worth a flier with the 1B depth when Vogey was out, but the problem with all the fetishizing over positional flexibility is that it encouraged Shelton to get creative. He hit well last year, is/was a decent prospect who is still reasonably young, and no disrespect to Martin, but out 1B depth and long-term outlook still isn't clear at all.
But it's time to churn and burn, and at the very least, I don't see how you throw him back in there. We'll face Fried tomorrow in Atlanta, so I'd bet Shelton gets him in there for that.
Chavis was the biggest problem with the sombrero last night. I'm not sure you bench Mitchell today after his mistake in the field. It was a weird hop and he just made the wrong snap decision, it happens. Keep that swing in the lineup, IMO -- I'd like to see him DH today, Swaggerty in LF, Vogey at 1B, and Marcano back at 2B.
