Brandon Phillips was back in the lineup Friday night after missing Thursday's game because of the aftereffects of a collision in Wednesday's game.

Phillips was given the SCAT2 test again Friday. He showed improvement from Thursday.

"We gave him the concussion test," Reds manager Dusty Baker said. "He got a 100 (Friday). He got 90 (Thursday). He's trying hard to get back in there. As long as he passed the test and the trainer said OK, that's what we look at."

The SCAT2 is a standardized test to measure concussions. It tests balance, coordination and memory skills.

Phillips took a knee to the head from Milwaukee's Aramis Ramirez in the third inning of Wednesday's game on a caught-stealing play. He left the game in the fifth after experiencing dizziness.
