CINCINNATI -- Reds third baseman Scott Rolen, who was placed on the 15-day disabled list with a strained left shoulder on Friday, was optimistic on Saturday that the injury wouldn't require more cortisone injections or surgery.

"I don't need a repair or anything," Rolen said. "I don't have a torn rotator cuff. I don't have a labrum that's torn."

Rolen missed most of 2005 with the Cardinals because of a torn labrum in the same shoulder that required surgery. It's been a problematic spot since. During his earlier DL stint from April 24-May 12, he received two cortisone shots on the shoulder to reduce his discomfort.

There was no specific incident that triggered the latest issue, but Rolen was in pain after the game and during Thursday's off-day spent at home in Indiana.

"I was driving back and called Paul Lessard, the trainer, and said, 'You can scratch me right now. Don't hold the lineup,'" Rolen said. "I've been fighting it here for a while. That might have been what I needed, was to actually be in pain. On the off day, I couldn't lift my arm."

Rolen was batting .242 with five home runs and 36 RBIs in 65 games this season. Planning to use the DL time to rest and rehabilitate, he's viewed the break as a chance to stop fighting it.

"I've been beating my ahead against the wall, scratching and clawing, trying to stay above .240," Rolen said. "I try not to be results oriented, but at the same time, you want to be productive for the ballclub. I wasn't helping the ballclub an awful lot offensively."

In first start, Frazier collects first three RBIs

CINCINNATI -- This time, Todd Frazier gets to stay in the Majors with the Reds for more than one at-bat.

On Saturday, Frazier made his first big league start, batting seventh and playing third base. He was recalled Friday from Triple-A Louisville when Scott Rolen went on the 15-day disabled list and notched his first Major League hit, a lined single to right field in the seventh inning after entering in a double switch.

During Saturday's 11-2 win, Frazier got his first three RBIs in the seventh inning, ripping a bases-loaded double high off the left-field wall. He just missed his first grand slam on the play.

On May 23, Frazier was called up by the Reds and debuted against the Phillies as a pinch-hitter at Citizens Bank Park. His bat sailed into the seats on his first swing and he eventually struck out. The Toms River, N.J., native had nearly 70 friends and family in attendance, but the thrill was short-lived. Frazier was sent down the following day.

"I was in Philly for a day, what are you going to do?" Frazier said on Saturday. "Now I'm here, playing and at third base. I couldn't ask for anything more."

The Reds made a late decision on Friday to place Rolen on the DL with a left shoulder strain and summoned Frazier, who did not arrive at Great American Ball Park until the fourth inning.

"I was just getting changed and was ready at 6:15, putting my socks on," Frazier said. "[Louisville manager] Rick Sweet tapped me on the shoulder and said, 'You have to be up there in an hour and a half. Pack your stuff and get going.' I thought he was joking at first, but he never jokes about that."

Miguel Cairo started at third base for Rolen on Friday, and manager Dusty Baker plans to use the veteran infielder there on Sunday. Baker liked the low-ball hitter matchup for Frazier against Braves sinkerballer Derek Lowe on Saturday. Going forward, Baker will mix and match at third base between Cairo and Frazier.

"I can't wear Miguel out, but I need some production out of Frazier, too," Baker said. "This is no tryout camp. We're trying to win games. Frazier has played more outfield than he has third base. Recently, we told him to play third -- because of Scotty's situation -- which he had in the past."

A shortstop when he was drafted as a supplemental first round pick in 2007 out of Rutgers University, Frazier can play third base, second base, first base and left field. He was batting .260 with a team-leading 15 homers and 46 RBIs in 90 games at Louisville this season.

"Third base is probably the most comfortable," Frazier said.

Inner ear problem keeps Bruce out of lineup

CINCINNATI -- Reds right fielder Jay Bruce was out of the lineup for a second straight game on Saturday because of dizziness.

"He is terrible," Baker said. "Right now Jay is having an inner ear problem. He just woke up with it. I just saw him the afternoon before and he was great, walking his dog and seeing his girl. That's why as a manager, you have to get here early because you don't know what can happen overnight."

Fred Lewis got the start in right field Saturday against the Braves.

It was not known when Bruce might return to the lineup, but he did enter Saturday's 11-2 win as a pinch-hitter. The Reds trailed, 2-1, when his sixth-inning leadoff double to right field off Derek Lowe sparked a three-run rally that gave Cincinnati the lead for good. After the hit, Bruce was lifted for pinch-runner Mike Leake.

Worth noting

For the second time this season, third-base prospect Juan Francisco was not available to replace Scott Rolen when he was injured. Francisco is on Triple-A Louisville's DL because of a torn meniscus in his right knee. When Rolen was on the DL earlier this season, Francisco was out with a strained calf.

"I knew there were going to be 40-45 games we weren't going to have Scotty," Baker said. "But now we don't have Francisco either because he is on the DL."
