CINCINNATI -- The Reds on Friday optioned left-handed pitcher Tony Cingrani to Triple-A Louisville and selected the contract of right-handed reliever Jumbo Diaz from Louisville.
"We hope that it's a very short stay, because I do believe we're a lot better with Tony on our club," Reds manager Bryan Price said.
In a 4-3 loss to the Pirates on Thursday, Cingrani issued three walks in 1 2/3 innings and walked home the winning run with the bases loaded in the bottom of the 12th inning. He was moved to the bullpen on Saturday after Mat Latos took his spot in the rotation.
Cingrani was 2-8 with a 4.55 ERA in 13 games, including 11 starts. He will start for Louisville to get back his command back.
"That gives him a chance to know when he's going to throw, to know when he has a side day," Price said. "I think the side days are going to be important. When he comes back here -- as it stands right now if we had no injuries -- he'd be coming back as a reliever."
Marshall needs surgery, moved to 60-day DL
CINCINNATI -- Reds left-handed reliever Sean Marshall got the news all pitchers hope to avoid. Marshall will need to have left shoulder surgery. He was moved from the 15-day disabled list to the 60-day DL on Friday to make room for reliever Jumbo Diaz on the 40-man roster.
Marshall is scheduled to have his operation on Tuesday to debride -- or clean out -- his troublesome shoulder. The timetable for a return remains unknown.
"You know a lot more once you're in there," Reds manager Bryan Price said. "There are some issues in there that aren't going to get better through strength and stretching and things of that nature."
Marshall had a 7.71 ERA -- with 23 hits, 12 earned runs, 12 walks and 14 strikeouts -- in 15 games over 14 innings. He retired only five of 15 first batters faced, and five of his 11 inherited runners scored.
Shoulder problems limited Marshall to 16 games last season, and he began this season on the DL when he had more issues during Spring Training. When he returned on April 19, he still lacked velocity and any real consistency. Marshall was placed on the DL again last Friday.
"It's definitely not something I'm excited about," Marshall said of the surgery. "I've been able to stay off the surgery table my whole career and I've never been on the surgery table before in my life. I'm pretty nervous about it, but I think in the long run it'll help this team win some games. The doctors are very confident in what they can do and how they can make me feel."
Joining Marshall on the 60-day DL is right-handed reliever Trevor Bell, who has been out since April 8 with elbow trouble. Bell had been on a rehab assignment at the team's complex in Arizona.
"His elbow got sore again. They found that he probably was going to need Tommy John surgery," Price said.
And in one more transaction, starting pitcher Brett Marshall was activated from the 60-day DL and optioned to Triple-A Louisville.
No deal close with Cuban pitcher Iglesias
CINCINNATI -- There were multiple reports on Friday that the Reds were close to signing Cuban free agent pitcher Raciel Iglesias. However, a club source said there was interest in Iglesias, but that nothing was close to being done.
Iglesias, a 24-year-old reliever, threw in a showcase for big league scouts last month. He pitched for Cuba in the 2013 World Baseball Classic.
In November, Iglesias successfully defected from Cuba. He currently resides in Mexico.
Price: No concern over Broxton's velocity
CINCINNATI -- Reds reliever Jonathan Broxton showed some diminished velocity and lacked command during a rare less-than-effective appearance in Thursday's game vs. the Pirates.
Pitching in the ninth of what was a 4-3 loss to Pittsburgh in 12 innings, Broxton walked two in two-thirds of an inning. He reached 92 mph, but also was hovering in the upper 80s.
Manager Bryan Price was not concerned.
"He wasn't sharp. It was a combination. His slider wasn't real good. His velocity wasn't real good, which is fine. He's pitching without his best velocity all year," Price said. "He's coming off elbow surgery, so he's going to have days like that. He wasn't sharp and the hitters had some comfortable swings, so it made sense to go to [Aroldis] Chapman there."
