LOS ANGELES -- Through their first 81 games, including Wednesday, the Reds have used only their original five starting pitchers in 2012 -- Johnny Cueto, Bronson Arroyo, Mat Latos, Mike Leake and Homer Bailey.
According to the Elias Sports Bureau, it's the Reds' longest streak to begin a season with only five starters since the 1898 team made every start through its first 147 games with Still Bill Hill, Pink Hawley, Frank Dwyer, Bill Dammann and Ted Breitenstein. The club's modern record was 79 games in 1992.
"It says something about them, how've they taken care of themselves and the fact that they're younger," Reds manager Dusty Baker said of his rotation. "They're more experienced than most at their age. They train hard. Our medical staff and fitness people hopefully have found a formula on each one's workload -- training-wise, fitness-wise and how we've tried to use them. You can tell lately that it's the time of year where we can stretch them out a little more."
Rolen sits fourth straight game with back spasms
LOS ANGELES -- Reds third baseman Scott Rolen has continued to get treatment for his lower back spasms but was out Wednesday for a fourth straight game.
General manager Walt Jocketty is contemplating making a roster move.
"I'll know better probably the next day or so," Jocketty said. "We may end up doing something. He was feeling better today, so we'll see."
Rolen, currently listed as day to day, does not know when he might return.
"Hopefully in San Diego," Rolen said.
The Reds conclude the first half with a four-game series against the Padres beginning Thursday.
"I'm mobile and walking around," Rolen said. "No, I'm not comfortable. I'm not going to do any baseball stuff. I am getting around better, for sure, and improving. But I've not progressed to jumping jacks yet."
Soreness halts throwing program for Masset
LOS ANGELES -- Reds reliever Nick Masset, who has missed the entire season with a right shoulder injury, has been at the team's complex in Goodyear, Ariz., the past few days. However, Masset has not thrown to hitters yet. Actually, he has not thrown at all because of soreness.
"We'll give it a few days to hopefully let the treatment calm everything down so he's pain free," Reds head trainer Paul Lessard said. "When he has a pain-free range of motion, he'll start throwing."
Masset has had five bullpen sessions off of a mound since resuming his throwing program. He was with the club in San Francisco last week but only threw off of flat ground.
