"Hicks is better today and available," Gardenhire said. "He came in and told me he could play, but I was leery of starting him in case his back started to act up. So we'll start Santana out there."
Hicks said his back started to stiffen up on the lower left side while taking batting practice on Wednesday. He said he thinks all the extra work on hitting from the right side now that he dropped switch-hitting might've caused the back stiffness.
But Hicks said the anti-inflammatories he took on Wednesday helped and that he was available to pinch-hit, if needed.
"It's feeling a little bit better," Hicks said. "I'll be available. They gave me some medicine for the inflammation, and it's made it better."
With Hicks out, Santana made his fourth career start in center field. Gardenhire said the natural shortstop is still adjusting to playing center field but has done OK filling in for Hicks in center field.
"He's all right," Gardenhire said. "We all see he has plenty of range. But he has trouble with those rockets hit over his head. He'll have to adjust to that. But he covers left to right really well."
