CINCINNATI -- The radar readings might have been in dispute on Monday, but there was no question that the life was more than back in Aroldis Chapman's prized left arm.

For the first time since he worked with subpar velocity on Wednesday in San Diego, Chapman emerged from the Reds' bullpen and worked the ninth inning of a 9-3 loss to the Pirates. It was a 1-2-3 inning with one strikeout. His first two pitches to Pittsburgh's Kevin Correia were clocked at 100 mph by Pitch F/X on MLB.com Gameday. In Chapman's third pitch to Andrew McCutchen, the scoreboard radar display showed 106 mph, as the crowd cheered. However, the television broadcast radar read 105 mph and Pitch F/X had Chapman reaching a top speed of 102. Had the 106 mph been legitimate, it would have broken his previous record of 105.1 mph set in September last year in San Diego.

"I feel good. I don't think my speed went away," Chapman said through his interpreter, Tomas Vera. "It was just like a normal day, like any other pitcher. My arm wasn't feeling as well as it is and that's it. My arm never felt bad."

Chapman was told to rest his arm for a few days because of inflammation after he turned in fastball speeds mainly in the low-to-mid 90s on back-to-back days vs. the Padres. He made only 10 pitches on Wednesday and looked erratic. Catcher Ramon Hernandez alerted the club that afternoon and suggested that Chapman be removed from the game, much to his displeasure. Chapman downplayed that issue on Monday.

"I never worry about those things," Chapman said. "All that happened is when you don't have what you've got usually, you just try to do the job that you do with all the pitches. That's what I was doing."

Reds manager Dusty Baker and the club are still finding ways to optimize Chapman's ability without wearing him out.

"Can you afford to give him three or four days off so he can throw as hard as he did tonight? Or will he get conditioned to going a couple of days in a row?" Baker said after Monday's game. "Remember, everybody wanted him to be the closer. You can't be the closer right now going a couple of days a week. A closer has to go three, four, five days in a row sometimes. Then you might not use your closer for a week. That's how things go.

"We were hoping he could sort of step into Arthur Rhodes spot, along with [Nick] Masset. Masset is struggling some, and Chapman hasn't acclimated to consecutive days yet like that role requires. We might have to do more mixing and matching than I'd care to but have to."

Hermida called up; Francisco lands on DL

CINCINNATI -- The Reds on Monday placed backup third baseman and primary lefty pinch-hitter Juan Francisco on the 15-day disabled list with a strained left calf.

Outfielder Jeremy Hermida had his contract selected from Triple-A Louisville to replace Francisco on the bench. To clear space for Hermida on the 40-man roster, reliever Jared Burton (right shoulder inflammation) was transferred to the 60-day DL.

Francisco was injured in the eighth inning of Saturday's 11-2 win vs. the Pirates. He hit a single and hopped on one foot up the line. Hermida, who was signed to a Minor League deal in the offseason as a non-roster player at Spring Training, joins the club after a strong start at Louisville.

"That's what I asked him to do," Reds manager Dusty Baker said of Hermida. "At the time, I said go down and bust your butt. If something happens, I want to be able to call up a guy that's hot."

In 10 games for Louisville, Hermida was a .333/.405/.606 (AVG/OBP/SLG) hitter, with two home runs and eight RBIs.

"I tried not to look at the big picture and just go out there and produce every day," said Hermida, who was formerly with the Marlins, Red Sox and A's. "You never know what's going to happen up here. I've been on both sides of it. You see things happen during the course of a season, so all you can do is keep yourself ready, and hopefully, [an] opportunity presents itself."

Hermida, 27, was one of the final cuts in camp despite batting .342 with three homers and six RBIs. Not making the 40-man roster cost him since the Reds could not create space. He was given the opportunity to seek a big league job elsewhere before reporting to Louisville.

"I wanted to be here the whole time," Hermida said. "I always did. Coming in this offseason, this is the team I wanted to be a part of. We looked out there, but this was a good situation and the place I wanted to be. The timing of it was a little unfortunate at the beginning, but I'm excited to be here now."

Bailey slated for another rehab start

CINCINNATI -- Reds pitcher Homer Bailey was back in the clubhouse Monday, one day after making his rehab start for Triple-A Louisville. Bailey, who threw 62 pitches over five scoreless innings, was optimistic about his outing. He is trying to return from a right shoulder impingement that occurred during Spring Training.

"It went pretty good, all things considered," said Bailey, who allowed two hits and one walk. "I didn't feel any pain, which is plus No. 1. Early on, I felt really good. Once you start doubling your pitch count from one game to the next -- I felt pretty tired in the middle of the fifth. That kind of goes with the territory when you're building up your pitches."

Bailey walked his one batter, the eighth hitter ahead of the pitcher, in the fifth. He also said he was working on stuff. He is tentatively scheduled to pitch again Friday for Louisville at Columbus, Ohio, and make up to 85 pitches. If all goes well, he could return for an April 27 big league game in Milwaukee.

Phillips misses fourth straight game

CINCINNATI -- Reds second baseman Brandon Phillips was out of the starting lineup for the fourth straight game on Monday because of a sore right groin.

Manager Dusty Baker said it was "probable" Phillips could return on Tuesday when the Reds open a three-game series vs. the D-backs.

"He was a little upset today. Whenever they tell me they're ready, I try to give them another day," Baker said. "If he passed all his tests today ... because he still felt something going in one direction and turning the other direction. I know if that happens during a game, he's going to overextend the way Brandon plays all the way."
