Volquez turning it around at Triple-A Louisville

CINCINNATI -- Reds manager Dusty Baker on Sunday had the kind of conversation he likes to have with Triple-A Louisville manager Rick Sweet. Part of it was about the complete-game performance Edinson Volquez had on Friday against Charlotte.

Volquez, who sent down for the second time by the Reds on July 7, allowed two runs and five hits with no walks and nine strikeouts. Of the 110 pitches he threw, 82 were strikes.

"I thought it was awesome," Baker said. "[Sweet] said he had great command. It was great to see. Hopefully he can continue doing that. Then we'll bring him back up here eventually."

In three starts for Louisville this month, Volquez is 1-0 with a 3.00 ERA, five walks and 17 strikeouts. During his first stint at Louisville in May, the right-hander was given two starts before getting a recall. This time, the stay down below is open ended.

"This time, it's just pitch," Baker said. "Get on a roll and bring it here. He has as good of stuff as anybody in baseball."

Cozart on DL with elbow injury; Janish recalled

CINCINNATI -- The Transformers-like hardware affixed to Zack Cozart's left elbow on Sunday made his injury look worse than it was.

Cozart, the Reds rookie shortstop, was fortunate to only have to wear a metal brace and pressure sleeve for the hyperextended elbow. But the bad news was he still needed to go on the 15-day disabled list. Shortstop Paul Janish was recalled from Triple-A Louisville to replace Cozart.

"I was just starting to get comfortable up here," said Cozart, who was batting .324 in his first 11 big league games since a July 7 promotion. "I had my routine down. It's frustrating since I've only been up here a couple of weeks or so. It's a freak accident and it happens. Now I have to deal with it."

Cozart, 25, was injured in a fourth-inning collision at second base with Atlanta baserunner Nate McClouth. On a fielder's-choice play, Cozart was receiving a throw from Joey Votto when McClouth slid into his left arm. Cozart immediately grabbed his elbow in obvious pain and was on the ground for several moments before being walked off of the field.

X-rays were negative and Cozart went for a MRI that confirmed the hyperextension.

"I tried to get around him to catch the ball," Cozart recalled. "I knew the ball was sinking on the other side of him, but I didn't have time to do it. Right when I went down to get it, he's sliding in and I think I hit him in the chest or upper leg. I was already extended perfect and when I got it, it went the wrong way. It didn't look that good and didn't feel good. Hopefully it won't take too long."

There was no timetable on Cozart's return, but he hoped to start swinging a bat again within a week. He will wear the brace for a few more days.

"We're just trying to let that calm down and do some icing," Cozart said. "After that calms down, we're going to do some strengthening stuff and try to get back as quick as possible."

Baker to mix and match with Janish, Renteria

CINCINNATI -- With Zack Cozart going on the disabled list, the Reds recalled shortstop Paul Janish from Triple-A Louisville on Sunday. Janish, who entered the season as the regular shortstop, was sent down on July 7 to make room for Cozart on the 25-man roster.

Before his demotion, Janish was batting .227 with no homers and 19 RBIs in 68 games for the Reds and made 59 starts. The day he was sent down, he was on the phone with Louisville manager Rick Sweet and immediately got to work with hitting coach Smokey Garrett.

"It's been a few years since I was down there," said Janish, who was last in Triple-A in 2008. "I started out slow, but the past week to 10 days, I felt good. It's been a good feeling to go up to the plate and feel some consistency for the first time in a while."

Janish, 27, started out 1-for-22 at Louisville but was batting .256 (11-for-43) before his recall. He said he made some mental adjustments more than mechanical swing changes while working with Garrett.

"It's one of those situations where you have to take advantage of the circumstances, even if they weren't ideal," Janish said. "It was situation where you had to swallow it and some adjustments had to be made for sure. I felt like it was productive."

Veteran Edgar Renteria, who was Janish's backup when the season began, started at shortstop for Cincinnati on Sunday night against the Braves. Renteria entered the night batting only. 239, but had a pair of two-hit games since the All-Star break.

"We'll mix and match both of them as of right now," manager Dusty Baker said. "This is sort of Edgar's time of the year we were trying to get him to in the heat. It looks like he's looser. His bat speed is better and he's moving smoother and looser."
