I don't like that trade for the Twins. Morneau is a better 1B than Millar so Morneau would probably remain at 1B, so essentially they're getting a DH because Millar sucks even worse in the outfield and the Twins outfield is solid. Millar has little power and doesn't hit for a great average, not really what they want in a DH. They can probably get just as much production from Lew Ford as they would from Millar. I agree they need another bat but I don't think Millar is the answer. With pitching as deep as there's they could probably get something better. If it went through I'm guessing their lineup would be something like this
1. Stewart LF
2. Boone 2B
3. Mauer C
4. Morneau 1B
5. Hunter CF
6. Millar DH
7. Jones RF
8. Cuddyer/Punto/Rodriguez 3B
9. Castro SS
Unless I'm missing something
