Owings' injured right forearm is improving

SAN DIEGO -- Padres long reliever Micah Owings said his strained right forearm is feeling better.

Owings went on the disabled list on Thursday. He said the results of an MRI on Friday were encouraging.

"Structurally, everything looked good," Owings said.

Owings went on the disabled list for the lingering injury after he experienced discomfort when he threw Wednesday against the Nationals. He allowed a run in 1 2/3 innings during the outing.

"I treated it the end of the Colorado trip all the way up to the homestand, and it was still bothering me," Owings said. "[I] didn't feel sharp, didn't feel like I could extend with it, so I knew something was a little bit off. I can rely on [the training staff] to help get it right."

Quentin set to begin rehab assignment

SAN DIEGO -- Padres outfielder Carlos Quentin is expected to begin a rehabilitation assignment with Triple-A Tucson on Tuesday. The stint will likely last more than seven games, manager Bud Black said.

Quentin is expected to be the designated hitter on Tuesday and play in the outfield on Wednesday. He'll switch from being the designated hitter and playing in the outfield during the rehab assignment.

"Carlos looked good, and he's excited about going out," Black said. "Our medical staff and Carlos both feel as though he's ready.

"He had a good weekend in San Francisco, doing a lot of early work. He's confident."

Quentin ran the bases and worked on diving back to the bag and tagging up at third base on fly balls before batting practice on Monday.

"It was good," Quentin said.

Black pointed out that Quentin got just 15 at-bats during Spring Training before he suffered his right knee injury. Quentin underwent arthroscopic surgery on March 19 to repair meniscus tearing and to remove loose particles in his knee.

"A regular player going through Spring Training, it's usually 50-70 at-bats," Black said. "I don't know if he's going to get that many [during the rehab stint]. He's been down for well over a month. He needs to see the ball. He needs to get his stamina back to play nine innings."

Stauffer set for another rehab start on Friday

SAN DIEGO -- Padres starting pitcher Tim Stauffer is expected to make his next rehabilitation appearance on Friday with Triple-A Tucson.

He'll throw about 75 pitches in the outing, and a third outing is possible, Padres manager Bud Black said.

Black said Stauffer felt good and was experiencing normal soreness on Monday, a day after he made his first rehab appearance. He allowed two runs and six hits, struck out three and walked none in 3 2/3 innings with Class A Lake Elsinore on Sunday. He gave up a run in the third inning and a run in the fourth inning.

"We talked a little bit today about his stuff," Black said. "His slider wasn't as good as he hoped, but it was a step in the right direction physically."

Stauffer went on the disabled list April 5, retroactive to April 4, for a strained right elbow.

Padres aren't handing out many free passes

SAN DIEGO -- While the Padres have struggled offensively and defensively during the first month of the season, their pitching has been a strong point.

And the pitchers had an impressive streak to back that up.

Before Clayton Richard walked the Giants' Buster Posey in the sixth inning in Sunday's 4-1 loss in San Francisco, the Padres had issued no walks for 26 consecutive innings against 104 consecutive batters, according to the Elias Sports Bureau. The Padres' last walk before Posey had been to the Nationals' Wilson Ramos with two outs in the fifth inning on Thursday at Petco Park.

"I wasn't aware of it," Padres pitching coach Darren Balsley said. "I know when we're walking too many people. But I expect our guys not to issue a lot of walks.

"It is impressive, but it's also expected."

Earlier in the season, Balsley said he was concerned the pitchers were issuing a few too many walks, but that number has diminished.

"We have a fairly young staff," he said. "Through their work ethic and side work, they're learning to execute quality pitches."

The streak of 104 consecutive batters faced without issuing a walk was the fourth-longest streak in Padres history. The 26 straight innings without a walk is tied for the fifth-longest streak in club history.

The longest streak in Padres history is 32 consecutive innings and 122 consecutive batters faced without a walk, which occurred from July 28-31, 1971.

"I hope the four walks in three games becomes more of the norm than an aberration," manager Bud Black said. "What we don't want is the bad walk, the two-out-nobody-on walk, the walk to the eighth-place hitter when the pitcher is up."
