Twins outfielder Aaron Hicks was scratched two hours before the first pitch Wednesday because of back spasms.
Hicks said he felt good during an early batting practice session but tweaked his back during team batting practice. He said it could be due to the amount of righthanded swings he has taken over the past few days since he stopped batting from the left side.
"I think I might've just overworked it and trying to do too much," Hicks said.
Danny Santana replaced Hicks in center field and batted ninth. He went 0-for-1 with a walk and a strikeout.
Hicks didn't rule out the possibility of playing Thursday, but he said the spasms have created discomfort.
"I'm just going to take some pills, sleep on it and see how it feels tomorrow," Hicks said.
Pelfrey update
Pitcher Mike Pelfrey had a setback in his rehab assignment due to right shoulder discomfort and flew back to Minnesota to be evaluated on Wednesday night.
Antony said Pelfrey was reporting soreness and stiffness in his shoulder on Tuesday, four days after his second rehab start with Class AAA Rochester. Pelfrey pitched five scoreless innings, allowing four hits and two walks on Friday.
