HOUSTON -- Padres shortstop Everth Cabrera will begin a Minor League rehabilitation assignment on Monday, as Padres manager Bud Black said he was pleased with the way Cabrera's strained right hamstring reacted after two days of rigorous workouts at Minute Maid Park.

Cabrera, on the disabled list since April 30 (retroactive to April 27) with a strained right hamstring, took part in a series of drills on the field at Minute Maid Park before Friday's game and then did so again on Saturday.

Cabrera will fly Sunday to San Diego and will play for Class A Lake Elsinore on Monday -- which will be the first of three games he'll play with the Storm. He won't likely play on Wednesday and could rejoin the Padres as soon as Friday, when the team returns home to face the Dodgers at PETCO Park.

"He had a good day on the field," said Black, noting that Cabrera ran and took extra batting practice four hours before the game.

On Saturday, Cabrera missed his 11th consecutive game with the injury.

MRI confirms Young's shoulder strain

HOUSTON -- On Friday afternoon, Padres pitcher Chris Young received the results of his second MRI exam of the week on his injured right shoulder.

San Diego manager Bud Black said the MRI revealed Young has a strain -- which is exactly what the original diagnosis was.

Black said that Young -- on the disabled list since April 7 -- won't be evaluated again for another two to three weeks.

"In the meantime, he will work with the training staff on scapular stabilization exercises and rehab rehabilitation modalities to help strengthen the shoulder," Black said.

Black said he's hopeful that Young will be able to pitch again this season, and that rest and rehabilitation will heal the shoulder.

On Monday, Young had an MRI with contrast to enhance the scan. The MRI was sent to noted orthopedic surgeon James Andrews for evaluation.

Young then had a traditional MRI on Friday.

Earlier in the week, Young -- who tossed six scoreless innings in Arizona in his lone start of the season -- expressed his frustration with his shoulder.

"I want answers," he said. "I had this cleaned up last August. Why am I having trouble now? It's extremely frustrating."

Young had his 2009 season cut short because of arthroscopic debridement surgery that removed loose fragments in his shoulder last August.

Young's rehabilitation program, by his own admission, was smooth and without setback, including his time in Spring Training.

Hairston Jr. able to laugh off error

HOUSTON -- On their way to a 7-0 shutout over the Astros on Saturday, Jerry Hairston Jr. had what he said was the "most embarrassing moment in my life in the big leagues."

With two outs in the ninth inning, Padres reliever Ryan Webb allowed a double into the gap in left-center field off the bat of Kaz Matsui.

The relay throw came into Hairston, who was playing shortstop. As he readied himself for a throw to third base, he attempted to hold up on his throw. Only the ball came loose and actually hit second baseman David Eckstein, who was about 10 feet in front of him.

Eckstein was plunked on the left thigh with the ball. Matsui, seeing this, ran toward third base and Hairston was charged with an error. The next batter, Carlos Lee, grounded out to end the game.

"I was trying to hold up and the ball went right to him [Eckstein]; he thought it was a lot funnier than I did," Hairston said. "I think he needs the error since he was the last one to touch it."

Eckstein showed the red mark on his leg to pitcher Mat Latos prior to Saturday's game. Latos, who earned the victory with eight scoreless innings, turned to Eckstein and with a straight face said, "I think he [Hairston] did it on purpose."

Latos joins Padres' lore

HOUSTON -- Padres pitcher Mat Latos' eight scoreless innings in Friday's 7-0 win over the Astros was significant on a lot of fronts.

The eight innings marked his longest outing as a Major Leaguer, and the nine strikeouts he compiled were a career high, as well.

Now there's this: According to Elias Sports Bureau, Latos became the fourth pitcher in club history to toss eight shutout innings with only two baserunners allowed.

The three other Padres pitchers who have pitched at least eight innings, allowed two or fewer baserunners and registered at least nine strikeouts in a game were: Clay Kirby (September 18, 1971), Bruce Hurst (April 10, 1989) and Andy Benes (July 3, 1994).

Latos and reliever Ryan Webb combined on the shutout, the seventh of the season for the Padres. The seven shutouts lead the Major Leagues.
