SAN FRANCISCO -- Reds second baseman Brandon Phillips was cleared to return to the lineup Friday after he missed one game with lasting effects from a collision.

Phillips passed his SCAT 2 concussion tests, which check his balance, speech and memory.

"He did very well. He told me he was doing better today," head athletic trainer Paul Lessard said. "I'm sure he had a mild concussion. That's the way I'm treating him."

However, Lessard noted that Phillips' symptoms were not severe enough to warrant a stint on the seven-day disabled list specifically for concussions.

Phillips exited early from Wednesday's game vs. the Brewers when he felt dizzy after taking a shot to the head from a sliding Aramis Ramirez as he was caught stealing second base. Less than an hour before Thursday's series opener, he was scratched when he showed to be less than 100 percent while hitting and taking ground balls.

"He got 100 today and got a 90 yesterday," Reds manager Dusty Baker said of Phillips' tests. "He was trying hard to lobby to get back in the lineup. As long as he passed the test and the trainer said it was OK, that's all it took."

Bray striving to improve after long layoff

SAN FRANCISCO -- After missing two months on the disabled list with groin and back injuries, Reds reliever Bill Bray feels OK following his first two appearances. Work remains to get back to being more effective.

"It's been a continual process of trying for improvement," Bray said Friday. "The other night I went out and I was pinning the ball behind my head in my arm swing. That's not what I do. That's not my motion. I'm working on improving my motion and my control. That's been the biggest thing. I've come in the past couple of games and walked the first guy I faced. That's not really something I've done historically."

Bray returned from the DL on June 22 vs. the Twins, inherited a bases loaded, one-out situation and walked in a run. On Wednesday vs. the Brewers, he inherited runners on first and second with no outs and got out of the jam clean.

"It was a huge confidence boost for me and something I can definitely build on," Bray said.

Baker enjoying reunion with 2002 Giants squad

SAN FRANCISCO -- It's sure to be a nostalgic weekend for Reds manager Dusty Baker. His former club, the Giants, is reuniting his 2002 National League championship team Sunday.

San Francisco lost the World Series to the Angels in Baker's final season before he moved on to the Cubs.

"I'm curious to see how they're doing in life and how things are with their families and what they're doing, business-wise," Baker said Friday. "Guys are stopping in. Benito [Santiago] came in, Marvin Benard came in. I'll see some more guys that I haven't seen in a while. It's always nice to see former players, tell some stories and just have a good time."

Worth noting

• Including Madison Bumgarner's shutout over them Thursday, the Reds have been dealt a one-hitter 30 times in the regular season since Philadelphia's Rick Wise threw a no-hitter on June 23, 1971.

• The Reds have used 29 players this season, the fewest in the Major Leagues.
