SAN DIEGO -- Though he'll have to wait a while for his second appearance after being sent back to Tucson Sunday morning, Padres reliever Cory Burns made a successful Major League debut Saturday in San Diego's 6-2 loss to the Mets.

Burns was called up prior to Friday's series opener and saw his first action Saturday, when manager Bud Black called on him in the fifth inning.

"My knees were a little shaky the first couple hitters, had a couple walks, but made some pitches," Burns said. "I felt good about my outing, felt good on the mound."

You really can't blame Burns for being a little weak in the knees. The first batter the 24-year-old faced in the big leagues was none other than Mets superstar David Wright.

"It was everything I could ask for," Burns said of having a player of Wright's caliber as his first Major League hitter. "It was kind of ironic when I got called up, [current Tucson Padres catcher Nick Hundley] came up to me and said, 'If you face David Wright, throw him changeups,' I ended up walking him, but made some good pitches."

Burns did well to mask his nerves. His composure, along with his changeup, made an impression on Black.

"When I handed him the ball, he had a good look in the eye. He looked composed," Black said. "We'll continue to monitor his work. There's a couple things he has to clean up, but ... his changeup is a pitch that I think can be successful in the Major Leagues."

Burns also got to bat in the game, marking not only his first big league plate appearance, but his first as a professional. Burns, in the midst of his fourth pro season, said he hadn't hit since 2005, when he was a member of the Glendale (Ariz.) High School team.

"It wasn't really nerve-wracking. ... We had a runner on second and I just wanted to put the ball in play," Burns said. "Wanted to try to make something happen, but the timing was a little off."

Burns found out Sunday morning that he was headed back to Triple-A. While he said he was surprised to be gone so soon, he understood the decision.

"The team needs some pitching," Burns said. "For the most part, I've thrown one inning all year, so when I go out and throw 40 pitches in two innings, it's a pretty easy decision for them."

Burns, though disappointed to hear the news and hopeful he'd be the one called upon the next time San Diego needs an arm, also said the experience is one he'll treasure.

"I was so happy to be here and proud to be a San Diego Padre that it's still running through me, it's an unbelievable feeling," Burns said. "I went to bed with a smile on my face."

Padres 'pen gets fresh arm in Mikolas

SAN DIEGO -- After needing 7 1/3 innings from the bullpen in the wake of Edinson Volquez's wild outing on Saturday, the Padres relief corps needed a fresh arm.

That arm -- a right one -- belongs to Miles Mikolas, who was recalled from Triple-A Tucson prior to Sunday's game. Right-hander Cory Burns, who made his Major League debut Saturday, was sent back to Tucson after two days with the Padres.

"We felt as though we needed some reinforcement in the bullpen," Padres manager Bud Black said. "We've gotten some short starts in the past week, that's the way it is."

"I suspect that Corey will be back. ... These guys -- Mikolas, [Brad] Boxberger, [Brad] Brach, [Nick] Vincent, Burns -- those guys are cutting their teeth," Black said. "This is all part of becoming a part of a Major League staff. It doesn't happen overnight where a guy gets called up and spends 12 years in the Major Leagues as a reliever."

Mikolas, who also made his Major League debut this season, is with the Padres for the third time this season. In his first two stints, the 23-year-old went 1-1 with a 3.86 ERA in 15 games. He struck out 14 in 16 1/3 innings, while walking 11 and yielding 14 hits.

The Tucson Padres were in Round Rock, Texas, for a game with the Rangers' Triple-A affiliate Saturday night when Mikolas was informed he'd be returning to the Majors.

"The rest of the boys in Tucson caught a plane to Albuquerque, N.M., and Miles caught a plane to San Diego, Calif., which is always a preferred flight for Triple-A players," Black joked.

Black also said Ross Ohlendorf, who is scheduled to start Tuesday against the Cubs, was available in the bullpen Sunday if length is needed.

Stauffer makes rehab start

SAN DIEGO -- Tim Stauffer, who was originally scheduled to be the Padres' Opening Day starter, continues to progress toward rejoining the San Diego rotation.

Stauffer, on the 60-day disabled list with an injured right elbow, made his second rehab start Saturday night for Class A Lake Elsinore, throwing his scheduled one inning and yielding two earned runs on three hits. Stauffer also went one inning with the Padres' Arizona League squad in Peoria on Wednesday, and manager Bud Black said the club is currently deciding where the 30-year-old will make his next rehab appearance, tentatively scheduled for Tuesday.

"Nothing too exciting, but it's something," Stauffer said of his short but successful outing. "I felt good, no issues ... encouraging sign."

"He threw all his pitches, got nicked for a couple runs, but overall he threw the ball well according to the Lake Elsinore staff," Black said. "[He had] Stauffer-like stuff, but maybe not where he'll get to once he gets his arm strength."

Stauffer made one start this season, a five-inning, three-earned-run showing in a no-decision against the Nationals on May 14. He was placed on the DL immediately following that start.
