Doumit, who was signed this offseason after playing the last seven years with the Pirates, is also expected to see time at catcher, right field and first base.
"I look at the DH more for Doumit than I do anything else right now," Gardenhire said. "I want to keep his bat in there right now. If we started today, Doumit would be my DH. But there's always options of putting Doumit behind the plate and having somebody else DH."
Gardenhire did add that he plans on using the DH role for Joe Mauer and Justin Morneau when they need breaks from playing the field.
"I'm going to use it kind of like a roving thing, but ultimately, I think Doumit, I plan on him being the DH more times than not," Gardenhire said. "Maybe a little spot play in the outfield. But I'm going to use it to protect Mauer and Morneau too and give them their days. That's the great thing about it, I finally got that guy who is multipositioned, who also catches. I've kind of been wanting that for a few years around here. It's good to have him here."
