CINCINNATI -- The Reds watched right-handed reliever Jason Isringhausen pitch on Tuesday and have prepared an offer.

Isringhausen threw in the bullpen, and general manager Walt Jocketty and pitching coach Bryan Price were among those impressed by the efforts of the Cardinals' 37-year-old former closer.

"He looked good," Jocketty said before Tuesday night's game. "He's a long ways from being able to pitch in a game, but he looked good, and ... he looked like he's healthy. He's going to have to go out and pitch for a while. I've got a call into his agent to talk to him and see what happens."

Jocketty was St. Louis' general manager while Isringhausen was in the Cardinals' bullpen, from 2002 to 2008. During that time, Isringhausen notched 217 saves and posted a 2.98 ERA. He last pitched in June 2009, for the Rays, before needing Tommy John surgery on his right elbow.

"I'd anticipate he's pleased with how well he threw in front of the staff," Price said. "It looks like he could go out and pitch somewhere. He threw like almost 40 pitches, 35 to 38 pitches. It didn't take him long to get loose and ready, four or five minutes of catch, and then he was getting after it. He looked very healthy to me."

Hamstring keeps Rolen on the bench again

CINCINNATI -- Third baseman Scott Rolen was out of the lineup on Tuesday for the fourth straight day as he tries to recover from a sore right hamstring.

Little had changed from Monday, and Miguel Cairo once again got the start in his place.

"I'm going to go stretch with the team, go out and throw a little bit and get my treatment and stuff," Rolen said. "I don't feel any better. I don't feel any worse right now."

And although catcher Ramon Hernandez was eligible to come off the disabled list on Tuesday, the Reds are waiting another day or two to activate him.

"I've got to see how the soreness is in his legs, because he did a lot of work yesterday," manager Dusty Baker said. "He blocked and he threw, he caught bullpens. No matter how you work, there's nothing like squatting down back there getting up and down, up and down. I can tell you at least it's not today. Maybe tomorrow, maybe Thursday."

Phillips given a rare day of rest

CINCINNATI -- Brandon Phillips received a rare day off on Tuesday night. The All-Star second baseman had played in all but one game this season entering Tuesday's action and leads the Reds in at-bats, with 384.

"Nothing is wrong. He hasn't had a day off," manager Dusty Baker said. "I could see him and Joey [Votto] are spent. It always happens after All-Star Games. If it was around the corner, it would be no problem. But they went coast-to-coast and back and didn't have any off-days. When you're tired, the first thing you lose is your concentration."

With Stephen Strasburg pitching for Washington on Wednesday, Baker said that Tuesday made more sense for the day off.

Phillips is batting just .194 in July after hitting .373 in June. Paul Janish took his place at second base, batting second.

"I just told [Phillips] to stay home, eat, sleep and show up late," Baker said. "I have to give Joey [a day] off, too, because I can see he's in the same boat, kind of."

Bruce battling struggles at the plate

CINCINNATI -- Jay Bruce has been trying to snap out of a slump at the plate, and he found plenty of people willing to give him advice over the weekend during the Reds Hall of Fame festivities.

"He's got everybody in the world giving him advice, talking to him," manager Dusty Baker said. "As Adam Dunn used to say, you've got to get out of your own head sometimes. Everybody cares, and everybody is trying to help him. The Hall of Fame night, four or five Hall of Famers had him corralled. But you can't blame them. Guys are trying to help, and they see things."

Bruce snapped a hitless streak in the first inning of Tuesday night's game with a one-out double off Washington's Luis Atilano. Bruce had gone 16 at-bats without a hit entering the night, and saw his average drop to .257 from .283 at the beginning of the month.

Matthews has option to opt out of contract

CINCINNATI -- Reds general manager Walt Jocketty confirmed Tuesday's report that outfielder Gary Matthews Jr. can opt out of his contract and become a free agent if he isn't promoted to the Majors by July 24.

In 20 games at Triple-A Louisville entering Tuesday, the 35-year-old Matthews was batting .310 with three home runs, five RBIs and a .355 on-base percentage. He was signed by the Reds to a Minor League deal on June 24 after being released by the Mets.

"We have to make a decision," Jocketty said. "We're not at that point yet. We'll see and evaluate the situation and whether he can help us now or not."

The Reds have five outfielders on the active roster -- Drew Stubbs, Jonny Gomes, Jay Bruce, Chris Heisey and Laynce Nix. Chris Dickerson is with Matthews in Louisville on a rehab assignment, and he went 4-for-9 in his first four games with a pair of doubles.
