Padres option slugger Clark to Triple-A

SAN DIEGO -- The Padres have moved another player over to the Minor League side, as manager Bud Black said on Monday that first baseman Matt Clark has been optioned to Triple-A Tucson.

Clark, who hit a home run on Sunday off Rangers right-hander Alexi Ogando, finished Cactus League play with a .419 average in 43 at-bats, collecting four homers and 13 RBIs. He'll be the starting first baseman for manager Terry Kennedy in Tucson.

"I thought he had a great spring, and we got him exposed to big league camp," Black said. "This year, he came to camp very comfortable and played with a lot of poise and confidence."

Black said that he expects the 25-year-old Clark -- the son of former Major League pitcher Terry Clark -- to continue to produce in 2012. Clark has 80 home runs in his first four professional seasons, but the Padres have Yonder Alonso, Jesus Guzman, Kyle Blanks and even Mark Kotsay for first base.

"This guy has produced -- a big left-handed bat who does a lot of good things at the plate," Black said.

Clark joins pitchers Joe Wieland, Casey Kelly and Jeff Suppan, who were also sent to Triple-A. Suppan is battling a right triceps strain and could open the season on the disabled list.

Prospective Padres Owings, Brach hopeful

SAN DIEGO -- The Padres held a workout on Monday at Petco Park in advance of their exhibition games on Tuesday and Wednesday against the Royals.

Not everyone who dressed inside the home clubhouse before the workout has made the 25-man roster for Opening Day on Thursday against the Dodgers.

Relief pitchers Micah Owings and Brad Brach each sat quietly in front of their respective lockers on Monday, awaiting the workout, while reporters scurried about, talking to other players.

The 25-year-old Brach, who has all of 29 days' Major League service time, didn't sound like someone who was feeling the least bit anxious, wondering if he'll open the season with the Padres or pitching for Triple-A Tucson.

"I guess they could have cut me three weeks ago," Brach said, smiling. "It's been an awesome spring. I hope it continues."

There's actually a good chance that both could make the Opening Day roster, especially if the Padres do place pitcher Tim Stauffer -- sidelined with a strained right triceps -- on the disabled list to begin the regular season. There had been no determination on Stauffer's status as of Monday.

Between the two relievers, Brach had the better of the springs for the Padres, posting a 1.69 ERA in 12 games. Owings posted a 7.62 ERA in nine games, though he allowed runs in four of those nine games. Both would slide into different roles if they made the team, Owings being able to work multiple innings, with Brach -- a closer in the Minor Leagues -- called on to work one inning.

The Padres have until 2 p.m. PT on Wednesday to set their 25-man roster for Opening Day.

Like Brach, Owings had a good attitude about the uncertainty of his situation. Owings said that he has been one of the final cuts in five of his last six seasons.

"I came in here, and there's a lot of good arms in the organization," Owings said. "I feel fortunate that I have had the opportunity that I've had."
