Padres to place Cabrera on disabled list

Shortstop has strained hamstring; Zawadzki to get call

SAN DIEGO -- Padres shortstop Everth Cabrera will be placed on the 15-day disabled list on Friday after he missed his third consecutive game with a strained right hamstring.

Cabrera had an MRI earlier on Thursday that determined the soreness he's experienced in recent days was indeed a strain.

The Padres will purchase the contract of infielder Lance Zawadzki from Triple-A Portland. He will be added to the 40-man roster and the 25-man active roster in time for Friday's game against the Brewers.

Zawadzki hit .308 in Spring Training and impressed manager Bud Black and the coaching staff with his play at shortstop, especially during the second half of camp.

Zawadzki is hitting .162 in 68 at-bats with Triple-A Portland.

To make room for Zawadzki on the 40-man roster, the Padres moved infielder Matt Antonelli to the 60-day disabled list. Antonelli had surgery on Thursday to repair a broken left hamate bone.

Jerry Hairston Jr. got the start at shortstop and hit leadoff Thursday as the Padres opened a four-game series against the Brewers at PETCO Park. He'll likely continue to play there on an everyday basis.

Cabrera hasn't started a game since Saturday against the Reds when he was hit on the left knee by a slider from Reds' pitcher Johnny Cueto. The soreness in the knee subsided but then came the pain in the hamstring.

Young likely to make Sunday rehab start

SAN DIEGO -- Pitcher Chris Young, who skipped a scheduled rehab stint Thursday with Triple-A Portland, threw a bullpen session before the Padres' game against the Brewers at PETCO Park instead.

Young was originally set to test the strained right shoulder with Portland in a game that was set for Salt Lake City. But the Padres backed off having him travel to make a start because of poor weather in Salt Lake City.

As it turns out, the move was a smart one, as that game was postponed because of rain.

If Young reports no soreness in the shoulder he'll likely make a rehabilitation start for Portland on Sunday in Salt Lake City.

Young landed on the 15-day disabled list a day after he threw six scoreless innings in Arizona on April 7.

"If everything is heading in the right direction, you should see him in a game Sunday," Black said.

Black gives three Padres relievers rest

SAN DIEGO -- You can bet the Padres were hoping for a long outing from their starting pitcher, Wade LeBlanc, against the Brewers on Thursday.

Manager Bud Black said before the game that the three pitchers who comprised the back end of the bullpen -- Luke Gregerson, Mike Adams and Heath Bell -- would probably not pitch in the opening game of a four-game series against Milwaukee.

The reason? Frequent work in recent days.

Gregerson, the Padres' seventh-inning specialist, has appeared in 11 of the Padres first 21 games of the season and in four of the past five games.

Adams, an eighth-inning specialist, and Bell, who has six saves this season, have appeared in nine games thus far. Bell has appeared in the past three games and Adams has pitched in three of the past four games.

If the Padres need a closer on Thursday, it would probably be reliever Edward Mujica.
