Time running short for rehabbing Cingrani

DENVER -- Left-handed starting pitcher Tony Cingrani, currently on Triple-A Louisville's disabled list because of a shoulder impingement, is not close to a return. Cingrani, who last pitched for the Reds on June 17 before a demotion, recently tried resuming a throwing program but was shut down after he felt soreness.

Reds manager Bryan Price said that Cingrani could receive a platelet-rich plasma injection to help speed his healing. It would require at least a week after the injection before he could try throwing.

The organization has not ruled out getting Cingrani back to the big leagues before the end of the season.

"He'd certainly be a guy we would like to see as a possible a mid-to-late September option," Price said. "But he's so far removed from pitching now. I don't want to say it's unlikely, but things are going to have to happen rather soon in order for him to be a consideration for September."

Strained flexor mass tendon sends Bailey to DL

DENVER -- Reds pitcher Homer Bailey will not make his next scheduled start on Saturday and is headed to the disabled list with a strained right flexor mass tendon near his forearm.

"That's going to keep him out for a while," Reds manager Bryan Price said on Thursday. "It's unspecific how long he'll be gone, but we certainly hope to have him back at some point in time during the year."

An official roster move was not made and Price and the club plan to name Bailey's replacement on Friday. The club played a man short on its 25-man roster Thursday.

Bailey was originally bumped back from a Wednesday starting turn because of elbow stiffness that stemmed from swinging a bat in his previous start on Aug. 7 against the Indians.

The Reds and Bailey were optimistic that he could make the Saturday start until he played catch on Tuesday and still didn't feel right.

"What happened was it didn't get any better. At one point, he felt like he had taken a step backwards," Price said.

An MRI exam on Wednesday revealed the injury. Bailey did not travel to Denver with the club and remains in Cincinnati.

"It certainly means there will be a week of no throwing and then we'll reassess," Price said. "He'll start to play catch. How quickly he bounces back will directly correlate with how quickly we get him back."

The flexor mass injury is similar to one fellow starting pitcher Mat Latos endured during an April setback as he tried to return from elbow and knee surgeries. It did not require surgery and Latos was back pitching in June. Last August, reliever Jonathan Broxton experienced a flexor mass tendon tear and had season-ending surgery.

Bailey, who signed a six-year, $105 million contract in February, is 9-5 with a 3.71 ERA in 23 starts this season. In four starts since the All-Star break, he is 1-0 with a 1.61 ERA.

On the Reds' 40-man roster, Triple-A Louisville's David Holmberg pitched on Wednesday and will not be available for Saturday. The best bet for the start could be right-hander Dylan Axelrod, who last pitched on Monday for Louisville and would be on regular rest for Saturday.

Axelrod, 29, appeared in 48 games -- with 30 starts -- for the White Sox from 2011-13 and had a 5.36 ERA. The Reds purchased his contract from Chicago on July 17. He is 2-1 with a 3.06 ERA in five starts since joining the Bats and worked a two-hit shutout to defeat Rochester on Aug. 5. On Monday, Axelrod worked 7 2/3 innings with four runs allowed for a win against Scranton-Wilkes Barre. He is not on the club's 40-man roster.

Bruce feeling better, back in lineup

DENVER -- One day after being scratched from the starting lineup on Wednesday against the Red Sox with an illness, Reds right fielder Jay Bruce looked vibrant and healthy on Thursday. Bruce was back in the lineup for the series opener against the Rockies at Coors Field.

"I feel 100 percent better," Bruce said. "It was like a 24-hour bug -- to the minute. It's crazy. I woke up this morning super hungry and ready to go. Last night from 9 o'clock until I went to sleep was the worst. I had a fever. I took few Advil, the fever broke and I felt great."

Bruce was particularly uncomfortable while flying with the team from Cincinnati to Denver on Wednesday night.

"I kind of slept all day yesterday. I was an emergency availability during the game and then made it here," he said. "It was long, long travel. I'm back today and ready to go."

Phillips to begin rehab assignment Friday

DENVER -- Reds second baseman Brandon Phillips will begin a Minor League rehab assignment at Triple-A Louisville on Friday. Phillips is working back from July 11 surgery to repair a torn left thumb ligament.

How many games Phillips will play is yet to be determined.

"I think we're going to reassess after Sunday and see how he feels and see if he needs more at-bats," Reds manager Bryan Price said. "He'll definitely play through the weekend."

Reliever Logan Ondrusek, currently on the disabled list with a right shoulder strain, is also expected to have his first rehab outing for Louisville on Friday.
