Morneau was penciled in to bat fifth and play first base, a spot he hasn't seen much time at this season. Of 20 games played, only four have come at first, while in 16 games, he's been the designated hitter.
"It'll be easier to get back in the flow of the game [playing first] than it will be DHing," Morneau said. "It's almost like pinch-hitting four times. It's hard to stay in the flow of the game. And without playing for 15 days, I think it would be difficult.
"With it being more of a tendinitis issue, getting tight and sitting there for three innings, then going up and swinging as hard as I can. I think being out there, throwing ground balls in between innings, being involved ... will have it help to stay loose."
The slugger had taken batting practice Monday and Tuesday and reported no pain in his wrist, which led to his activation. First baseman Chris Parmelee was optioned to Triple-A Rochester.
Manager Ron Gardenhire originally wanted to take a more cautious approach with the wrist injury and ease Morneau back into it, but after a conversation with Morneau, he agreed to playing him at first. However, it didn't guarantee he'd be there again Thursday.
"We'll see how it goes here, and then we'll make some decisions," Gardenhire said. "It's just nice to have him ... Just to have his bat in the lineup [and] his presence is huge."
