PHOENIX -- As the Reds have been playing their season, injured reliever Nick Masset has been watching from afar. Masset, who is trying to recover from right shoulder surgery to repair a torn anterior capsule, has remained in Arizona to work out at the Reds' player development complex in nearby Goodyear.
But Saturday, Masset was with the club at Chase Field and threw a bullpen session.
"It went really well," Masset said. "Lately, there's been some ups and downs. I had a setback about a week and a half ago. I started feeling some pain again. But we straightened some things out."
Masset missed all of 2012 with shoulder issues before having arthroscopic surgery in September. His throwing program was also halted at the end of Spring Training when he had a setback.
"That's been the recurring problem," Masset said. "I keep getting to the point where everything is going great and loose and I'm strong and flexible and my mobility is great. All of a sudden, I'll get a little pinch in the back of my shoulder. We've got to re-evaluate things to make sure everything is healing up OK.
"Right now, I'm cutting it loose pretty good. I'm fairly close to where I'm probably 100 percent fullspeed. But it goes from feeling completely normal to being my old self to what's going on here, and why all of a sudden is it acting up?"
Masset said he had thrown four bullpen sessions to date, and he hoped to get a few more so he could advance to face hitters in live batting practice. No target return date has been set.
"We could sure use him before the year is out," Reds manager Dusty Baker said.
That is Masset's wish as well. In the meantime, he will have to keep working his way back. His family has moved to the desert to be with him during his rehabilitation, and he watches Reds games from home each night.
"My hopes are to get back as soon as possible," Masset said. "We have to take the right steps in the right direction to put myself in the best situation to recover. As long as I'm feeling good, I will keep throwing. I can't really put a date on it. I just need to make sure I am healthy."
New position keeping Choo in shape
PHOENIX -- Nearly halfway into the season, it is safe to say that Shin-Soo Choo has done more running as a converted center fielder for the Reds than he ever had to do as a corner outfielder with the Indians.
Choo feels like his body has held up OK so far, but there is a little less of him than there was before the season.
"I've lost a lot of weight," Choo said Saturday. "At Spring Training I was 224-225, and now I'm 207-208 pounds. I feel good. I felt overweight at Spring Training. I feel lighter."
Choo, who entered Saturday's game against the D-backs batting .278 with a .462 on-base percentage after a scorching start to 2013, did not think his hitting was affected by having less weight.
"People think that if they lose weight, they lose power; I don't feel like that," Choo said.
During Friday's 11-5 Reds loss to the D-backs, Choo had to use all of Chase Field's expansive center field to make a catch. In the sixth inning, he ran all the way back to the fence to snag Martin Prado's long drive for a sacrifice fly. He bobbled it briefly but recovered to make the out.
"Last night, Prado hit it well," Choo said. "I just kept seeing the ball. It was one of those catches, nothing special."
• In the second inning Saturday, Jay Bruce's home run off of D-backs starter Patrick Corbin was his seventh off of a left-handed pitcher this season. Since the start of the 2010 season, Bruce leads all Major League left-handed hitters in homers against lefty pitchers with 41. He is followed by Curtis Granderson (34) and Carlos Gonzalez (33).
