SAN DIEGO -- Pitcher Miles Mikolas' introduction to the Major Leagues started rough, but ended on a high note.

Hours after he received his promotion to the Padres on Saturday, Mikolas entered his first Major League game. The 23-year-old right-hander pitched in the ninth inning of the Padres' 4-1 loss to the Marlins on Saturday night at Petco Park.

Against the first Major League batter he faced, Mikolas allowed a solo home run to Giancarlo Stanton on a full-count fastball.

That introduction to the Majors helped quiet Mikolas' jitters.

"I was like, 'Well, there it is. Welcome to the Major Leagues,'" Mikolas said. "Gotta get outs."

After the home run, Mikolas issued a walk to Gaby Sanchez before striking out John Buck looking. After Marlins starting pitcher Mark Buehrle laid down a sacrifice bunt, Mikolas ended the inning by striking out Jose Reyes looking.

"It felt good to get the first out, and to have it be a strikeout is nice," Mikolas said. "It's good for your confidence."

A native of Jupiter, Fla., Mikolas grew up a Marlins fan. Several of his friends and family members were able to catch Saturday's game on TV in Florida. He said his parents are planning trips to San Diego.

"It was great to know that I had that many friends and family watching the game," Mikolas said.

Mikolas joined the Padres on Saturday from Double-A San Antonio to give the club another reliever when closer Huston Street went on the disabled list for a strained right lat. Padres manager Bud Black said he likes Mikolas' stuff.

"That's a big curveball," Black said. "His challenge will be to get that in the strike zone. It has good rotation. You can combine that with a low-90s, mid-90s fastball. It's a nice variation. It's a nice difference of velocity. But the key is getting the breaking pitch in for a strike, because he's got enough fastball. There's no doubt about that."

Not much MLB closer experience for Padres trio

SAN DIEGO -- With Huston Street landing on the disabled list on Saturday with a strained right lat, the Padres need someone to close games.

Manager Bud Black mentioned Andrew Cashner, Dale Thayer and Luke Gregerson as candidates to close while Street is out.

Cashner has been a starter and reliever in his career, but he has never closed games in the Majors or Minors. However, he closed during his year at Texas Christian University. He is 2-1 with a 2.08 ERA in 13 innings for the Padres.

"Closing is always fun," Cashner said. "You get the ball with the game on the line at the end of the game and try to get the last three outs of the game."

Thayer accumulated 173 saves in the Minors and one save with the Rays in 2009. He has a 0.00 ERA in four innings with the Padres.

"It's always exciting," Thayer said of closing. "I haven't done it up here, so it's probably more pressure and it'd be more exciting to do it. It's always fun closing games out."

Gregerson closed games at Saint Xavier University, and he earned 48 saves in the Minors and three saves with the Padres from 2009-10. He has a 3.00 ERA in 12 innings with the Friars.

"As similar as the setup and closer role are, you do have that little extra adrenaline, a little extra something to get the job done, because it is the last inning," Gregerson said. "You have to finish it off."

Quentin among Padres' injury updates

SAN DIEGO -- Padres outfielder Carlos Quentin is expected to return to San Diego on Monday from his rehabilitation assignment with Triple-A Tucson to check in with the Padres, manager Bud Black said.

Quentin will then join Class A Lake Elsinore for more rehabilitation instead of accompanying Tucson on its trip to New Orleans, Black said. Quentin will play a couple of games with Lake Elsinore, but Black didn't specify when Quentin might finish his rehab.

The outfielder went on the disabled list on April 3 after undergoing right knee surgery. His status was one of several injury updates that Black provided on Sunday morning.

Starting pitcher Cory Luebke will likely seek a second opinion on his elbow injury in a couple of days. Luebke went on the DL on Wednesday, retroactive to April 28, for a strained left elbow.

Starting pitcher Tim Stauffer is expected to make a third rehab start on Wednesday, either with Lake Elsinore or Tucson, but more likely with Lake Elsinore, which will be playing at home, Black said. It could be Stauffer's final rehab outing. He went on the DL on April 5, retroactive to April 4, for a strained right elbow.

Outfielder Jeremy Hermida will join the Padres for their trip this week to Philadelphia and will see a specialist for his strained left adductor.

Minor League starting pitcher Casey Kelly is growing closer to playing catch at Tucson after resting his elbow.
