ATLANTA -- Saturday's 11-1 win over the Braves not only spared the D-backs' bullpen from having to pitch in a close game, it also gave the team a chance to get its first look at Carlos Rosa.

The right-hander, who was acquired earlier in the month from the Royals in exchange for Minor League shortstop Rey Navarro, worked a perfect ninth, his first action since being called up from Triple-A Reno earlier in the week.

"I liked what I saw," manager A.J. Hinch said. "He came right at guys, which is good. He's got a unique arm slot. The ball comes from a different angle, and he had plenty behind it."

Rosa struck out Eric Hinske to lead off the ninth, got Yunel Escobar to fly out to center and Nate McLouth to ground out to end the game.

"It's like new life for me," Rosa said of coming over to the D-backs. "I'm just so happy to be here. I was a little bit nervous pitching the first time for a new team."

Buckner to be called up for Tuesday start

ATLANTA -- Billy Buckner will be called up from Triple-A Reno to start Tuesday's game against the Marlins.

That means that Cesar Valdez, who had started in that spot in the rotation the last two times around, will move to the bullpen.

"We just think that Valdez's combination of the sinker -- getting the ball on the ground -- and his changeup against lefties gives us a little more versatility in the bullpen and a potential pitch maker down there to come in and troubleshoot whenever needed," Arizona manager A.J. Hinch said.

Buckner, meanwhile, was 3-1 with a 3.53 ERA in seven starts for Reno after losing out in the battle for the final spot in the rotation during the spring.

When he was sent down at the end of camp, the D-backs asked Buckner to use his signature curveball more often and to throw his fastball in on hitters.

"He fell in love with his cutter, and we felt like he lost his feel for his curveball," Hinch said. "So we wanted him to go down and be a true pitch mix guy. We think he's ready for another opportunity."

Snyder back behind plate for day game

ATLANTA -- Typically a day game after a night game means a day off for a starting catcher.

Not so for Chris Snyder on Sunday.

The D-backs catcher found himself in the lineup against the Braves despite playing the night before and after missing a large chunk of last season due to injury and losing his starting job to Miguel Montero.

"I had plenty of days off last year," Snyder said.

D-backs manager A.J. Hinch elected to play Snyder on Sunday because he wants to start backup catcher John Hester on Monday with Edwin Jackson on the mound.

"Hester is pretty good with Jackson in challenging him and making him throw his fastball," Hinch said. "They just seem to have developed a little repertoire in recent starts."

In addition, Hinch gave Snyder Wednesday off and the team had a day off Thursday.

"I still think he's fresh," Hinch said.

Snyder said the fact that Saturday's game was an 11-1 Arizona win also helped him.

"It was a comfortable win," Snyder said. "[Starter Rodrigo] Lopez did good. It was a fairly quick game. It's the games where you just grind and you're physically and mentally exhausted afterward, those are tough to get up the next morning and do it again."

Worth noting

Kris Benson is scheduled to throw 45-50 pitches Wednesday in an extended spring game in Tucson, Ariz. The right-hander has been on the disabled list since shoulder soreness forced him to leave his start in Colorado on April 28. Five days after his Wednesday outing, Benson will join one of Arizona's Minor League affiliates for a rehab start. It's possible he could need more than one depending on how he feels and how long it takes him to get up to five innings. ... D-backs manager A.J. Hinch on outfielder Justin Upton's importance to the lineup: "We're a completely different team when he's right." ... Reliever Bob Howry continues to struggle to try to find success on the mound. The right-hander allowed four runs on two hits and did not retire a batter Sunday as his ERA rose to 10.67. "I wasn't going to leave him out there to bury himself," Hinch said as to why he took him out when he did. "And I didn't feel like he was going to be able to get himself out of that jam."
