"Teahen is better," manager Trey Hillman said. "He's still a little stiff. He'll stay inside and have treatment again today. Hopefully, if things progress today, he'll be outside and have some activity tomorrow."
Since his July 10 inside-the-park home run helped the Royals beat the White Sox, 4-1, Teahen has batted just .138 (4-for-29) with two RBIs. He was tried unsuccessfully in the leadoff spot for two games, then was rested for two days before returning to the lineup on Wednesday night and going 0-for-4. That was the last time he played.
In other medical news, left-handed pitcher John Bale is still rehabbing from a broken hand with Triple-A Omaha.
"I just reviewed his rehab DVD yesterday and saw everything he's done on his rehab visits," Hillman said. "Right now the velocity isn't as good as we'd like to see it; hopefully that's going to come back because he's pitching at 86, 87 [mph] right now."
Left-hander Jimmy Gobble, who went on the disabled list with a sore back on Tuesday, was throwing in the outfield before batting practice on Friday. He's expected to go on a rehab assignment next week if he makes progress.
