Padres option Quackenbush back to Triple-A

WASHINGTON -- Reliever Kevin Quackenbush's stay in the big leagues was a short one, though that was not entirely surprising.

Quackenbush, who was added to the 25-man roster on Friday for reinforcements, was optioned Sunday to Triple-A El Paso when the Padres reinstated outfielder Cameron Maybin from the 15-day disabled list.

Quackenbush appeared in one game, allowing two runs on 1 2/3 innings in the Padres' loss on Friday to the Nationals. The team needed a 13th pitcher because of two 12-inning games in the last week, and Quackenbush was summoned from Triple-A.

"It felt good to get my feet wet and get the first one [appearance] out of the way," Quackenbush said. "It was very exciting to be here."

Quackenbush flew Sunday to El Paso, where the Padres' Triple-A affiliate was to open its new ballpark on Monday.

Manager Bud Black said Quackenbush held his own in his first stint in the big leagues.

"The first time is a great experience," Black said. "He's passed a lot of the Minor League tests, which helped earn him a promotion. For him, it's continuing to pitch well in Triple-A. But there's a lot to like about him. He didn't scare off, and he threw strikes."

Maybin rejoins Padres, makes season debut

WASHINGTON -- After missing the first 25 games of the regular season, center fielder Cameron Maybin rejoined the Padres on Sunday and was promptly inserted in the starting lineup for the series finale against the Nationals.

Maybin ruptured his left biceps tendon making a diving catch in a Spring Training game on March 2. He and the team opted against surgery, choosing the rehabilitation route with the hope that he could return sooner rather than later.

"I'm here, ready to go," Maybin said. "[The rehabilitation] was long. I'm healthy, and that was my biggest objective."

Maybin responded by going 2-for-4 with a double and a run in the Padres' 4-2 win over the Nationals.

The Padres optioned reliever Kevin Quackenbush to Triple-A El Paso to make room for Maybin on the 25-man roster. Quackenbush, who was added Friday, appeared in one game, allowing two runs over 1 2/3 innings in a loss to the Nationals on Friday.

Maybin appeared in 10 games with El Paso since he officially started his Minor League rehab stint on April 11. He started slow but finished with five hits in his final five games, hitting a home run on Tuesday. All told, Maybin hit .243 in 37 at-bats.

Maybin had a higher frequency of harder contact the longer his rehab stint went, but that wasn't the checkpoint he needed to know that he was ready to rejoin the Padres.

"It was just playing games," Maybin said. "It was realizing my body felt good. That was my checkpoint."

Maybin had been in Sacramento with El Paso. And with the Padres heading to San Francisco late Sunday for a three-game series that starts Monday, manager Bud Black was asked why the team wouldn't just have Maybin meet them there.

"We felt we wanted to get him out here and in a game -- every game is important," Black said. "You don't want to put it all on one guy, because they all have got to do it. But Cam can do some things on the baseball field -- he has speed, has some power.

"It's good to have Cam back."

The Padres entered Sunday's game with the fewest runs in the big leagues (65). The Astros, who rank 29th, have scored 15 more runs (80).

Last season, Maybin spent time on the DL with first an impingement to his right wrist, which later required season-ending surgery. Maybin also missed time after he tore the posterior cruciate ligament in his left knee. All told, he played in just 14 games.

Maybin signed a five-year, $25 million contract extension in the spring of 2012. He'll make $5 million this season, $7 million in '15 and $8 million in '16. There's a $9 million club option for '17 that includes a $1 million buyout.

Quentin nearing rehab assignment after testing knee

WASHINGTON -- Outfielder Carlos Quentin, on the 15-day disabled list with a bone bruise in his left knee, will be on the practice field at the Padres' Spring Training facility in Arizona on Monday.

"He'll be taking [batting practice], fly balls and doing baseball activities," said Padres manager Bud Black. "Most of his work will be done on the field, and less in the weight room or training room."

Quentin, who hasn't appeared in a game this season, spent the last few days at Petco Park running on the field to test his knee. He's at the point now where limitations are few.

The Padres would love to get Quentin's bat in the starting lineup as soon as possible, though they want to make sure he's physically sound before they do so. The feeling is that Quentin could need five or so days before he's ready to start a Minor League rehabilitation assignment.

"It will be nice to get all of our guys back," Black said.

The Padres' top two projected hitters, third baseman Chase Headley (strained right calf) and Quentin are on the disabled list. That's not good news for a team that ranks 30th in baseball in runs (65).
