"It's not perfect right now -- I can tell you that," Twins manager Ron Gardenhire said. "We'll see how this DH thing goes, but it wasn't a great night last night as far as him running around on his leg. So I'm a little concerned."
Gardenhire said he'll continue to start Willingham at DH until his knee feels better, as it usually takes a few days for the cortisone shot to fully set in.
"He's still fighting through it," Gardenhire said. "Last night wasn't perfect. It feels better, but it wasn't great during the game. So we'll see how it goes today. He didn't feel great, so we talked about it."
Willingham finished Wednesday's victory 2-for-4 with two runs scored and an RBI.
