Brandon Phillips gave it his best shot. But he was scratched from the lineup about a half hour before Thursday's game.

Phillips took a knee to the head from Aramis Ramirez in the third inning of Wednesday's 8-4 loss to Milwaukee on a caught-stealing play. He stayed in the game until the fifth and then was removed.

He hit in the cage shortly after arriving at AT&T Park Thursday.

"I feel OK," he said. "I'm just going to go on the field (during batting practice) and see what happens. That's the only thing I can really say … Hopefully, I can help the team out."

Reds manager Dusty Baker wanted Phillips better than OK.

"The trainer said when he runs around and gets the blood flowing, he could feel better or he could feel the same," Baker said. "If he feels the same, he's not playing."

Apparently, Phillips didn't feel better after the activity. Baker didn't want to risk playing him.

"Especially in this twilight with these hard throwers," Baker said.

Is Phillips concerned that he has a concussion?

"To tell the truth, that word came up yesterday," he said. "I'm trying to stay positive. I've never felt like this before … It's my birthday and I'm happy."
