Denorfia progressing with sore right shoulder

PEORIA, Ariz. -- Padres manager Bud Black remained optimistic on Wednesday that outfielder Chris Denorfia would be ready for the first game of the season on Sunday against the Dodgers.

Denorfia hasn't played in Cactus League games since March 18 because of a sore right shoulder.

"I'm progressing," Denorfia said, on his way for treatment.

Black said that Denorfia would play catch on Wednesday and take some swings in the batting cage with intensity.

"He's going to stay back and play in a Minor League game tomorrow and from there we'll make a day to day assessment," Black said. "But he's doing well."

Padres pointing toward weekend to set roster

PEORIA, Ariz. -- It appears the Padres will wait until Friday or Saturday to set their 25-man roster for the start of the regular season on Sunday against the Dodgers.

While it's likely that left-handed pitcher Robbie Erlin will be the No. 5 starter, there's still some spots up for grabs.

Since the Padres aren't going to carry a second lefty reliever, Donn Roach appears to have won a job as a second middle-to-long reliever, along with Tim Stauffer.

However, what is not as clear is how many catchers the Padres will initially carry on the roster and how the bench sets up.

Yasmani Grandal, less than nine months removed from ACL surgery on his right knee, has advanced to the point where he's been able to catch nine innings in a game.

Grandal could make the roster with Nick Hundley. But the team also likes Rene Rivera, who is out of Minor League options and figures to be scooped up by a team looking for a strong defensive catcher who can handle a staff as well.

If the Padres keep three catchers and then later try to option one to Triple-A El Paso, that will be much easier to do after the season starts when teams have set their roster.

The five-man bench appears to be infielder Alexi Amarista, the two catchers aside from the starter and outfielder Tommy Medica, though veteran Xavier Nady is in the running as well.

Black said Saturday, when the team faces the Indians in the second game of an exhibition series at the the University of San Diego, is the day when the final roster could be announced.

Wieland set to rehab, play catch in six weeks

PEORIA, Ariz. -- Padres pitcher Joe Wieland will be able to play catch in six weeks after having elbow surgery on Tuesday in San Diego.

Team doctor Heinz Hoenecke performed the procedure.

"The doctors found what was expected -- he had an impingement in the back of the elbow and they got rid of some hard pieces of loose cartilage, and they also did some shaving of the back of the elbow," manager Bud Black said.

"They suspect Joe will have a speedy recovery."

Black said Wieland will do his rehabilitation at Petco Park in advance of playing catch in six weeks. From there, he'll start a throwing program aimed at getting him on a mound.

Wieland, who had Tommy John surgery on July 27, 2012, experienced soreness in the elbow in a start on March 15. The soreness was in the same area where he had a triceps strain last year during his recovery and rehabilitation, which led to a stress reaction that slowed his rehab program.

Wieland flew to San Diego to have an MRI. He also visited with noted orthopedic surgeon and Reds medical director Dr. Tim Kremchek, who recommended surgery to the elbow joint.

Short hops

• Black said that pitcher Matt Wisler will start Friday's exhibition game against the Indians at the University of San Diego. Eric Stults, projected to be the No. 4 starter in the rotation, is set to start on Saturday. Tickets are still available for both games through the school.

• Third baseman Chase Headley proclaimed himself fit and ready for Sunday's opener. He started at third base on Wednesday a day after getting a lot of at-bats in a Minor League game. "I made a lot of outs," Headley said, smiling. He went into Wednesday's game with 14 at-bats in official spring games, as he missed time with a strained right calf -- seven from each side of the plate. He'll likely get a few more at-bats this weekend in the two exhibition games against the Indians.

• Outfielder Cameron Maybin (ruptured left biceps) has progressed to the point where he's taking swings in the batting cage. Maybin sustained the injury on March 2 making a diving catch. After an MRI, it was determined that he would likely miss between two and three months before playing in games.

• Outfielder Carlos Quentin was a late scratch on Wednesday with a sore left knee. Black said it was a precautionary move more than anything and that Quentin will be examined on Friday. "We just felt a Spring Training game wasn't the right time to push it," Black said. Quentin hit .152 in 33 Cactus League at-bats this spring with two home runs.
