Reds make themselves at home in San Francisco

SAN FRANCISCO -- Doubleheaders in this day and age of the Major Leagues are a rarity, so why not add some extra distinctions to the equation?

Reds clubhouse assistant Josh Stewart doesn't remember having to pack home uniforms for road trips in his 20 years with the club, but the Reds brought the same uniforms they wore Sunday against the Pirates in Cincinnati to San Francisco in anticipation of their two-game anomaly against the Giants.

The Reds will be the visiting team in the first game at AT&T Park, wearing standard grays. Then for the second game, the clubs will play a makeup game for their Fourth of July rainout in Cincinnati, making the Reds the home team in San Francisco. They'll change into their red alternate jerseys with white pants, topped off with their road batting practice hats, which Stewart also said have never been worn outside of BP.

Manager Dusty Baker has said he didn't shower between games of a doubleheader during his playing days, from 1968-86, and now that he's managing, not much will change.

"I'm not sweating anymore or sliding anymore," Baker said. "That's why I used to change before. Now that I'm managing, I wouldn't change unless the weather changed to put a turtleneck on or something like that.

Baker said the only time he's dealt with a similar situation was in 2004, when the Marlins played two games against the Expos at the Chicago White Sox U.S. Cellular Field because of Hurricane Ivan.

It was the first game between two National League teams in an American League venue since 1946, when wet paint forced the Boston Braves and Philadelphia Phillies to play at Fenway Park.

Hanigan should return to Reds on Thursday

SAN FRANCISCO -- Catcher Ryan Hanigan, on the disabled list since July 11 because of an injured left wrist, is still on track to return to the Reds when he becomes eligible to do so on Thursday.

"He's doing very well," Reds athletic trainer Paul Lessard said. "His catching with the left hand, and moving the glove has been fine. It's just the velocity of his swing and the force on his hand, which is kind of in question."

Hanigan restrained from swinging a bat for a week so he could heal, but Lessard said he should be ready to get back into action.

Sean Marshall, meanwhile, will throw again Tuesday as he continues rehabbing from a left shoulder injury. The left-hander threw from 60-75 feat on Monday for about 15 minutes, but he still has a ways to go.

"He's not ready to get back on the mound, by any stretch of the imagination," Lessard said.

Johnathan Broxton threw a bullpen session Monday as well and will throw a third on Wednesday. Monday's outing lasted 30 pitches and included fastballs and breaking balls, which is encouraging because he wouldn't be throwing breaking balls unless his fastballs were of a certain quality.

Cingrani or Reynolds likely to start Sunday

SAN FRANCISCO -- Reds pitchers Tony Cingrani and Greg Reynolds are starting in the two games of Tuesday's doubleheader at AT&T Park, which will also serve as a quasi-tryout to see who starts Sunday's series finale against the Dodgers.

Cingrani started despite having been optioned the Minor Leagues on July 17, because teams may add a pitcher to the roster for doubleheaders. He'll return to Arizona following the game to finish the 10-day stint required of players who have been optioned.

The left-hander will then be eligible to be recalled from the Arizona League Reds to start Sunday's game, which manager Dusty Baker said is more likely than Reynolds.

"We know very little about Reynolds," Baker said. "That's why Corky Miller is catching him, because he knows him from Triple-A. ... He's a guy that relies on defense. He's not a strikeout pitcher. So it's up to us to be in the best position without knowing anybody."
