SAN DIEGO -- Jimmy Jones, the pitching coach for the Padres' Double-A affiliate in San Antonio, joined the Major League team on Wednesday to fill in for bullpen coach Darrel Akerfelds, who has been battling pancreatic cancer.
Jones is in his fourth season as a pitching coach in the Padres' organization. The Padres selected him third overall in the 1982 Draft and he pitched for eight Major League seasons.
Jones will fill in for Akerfelds, who has been away from the team for most of the season. Akerfelds was diagnosed with pancreatic cancer in December 2010.
"We hoped this day wouldn't come where we had to bring somebody for Ak, but where Ak is right now, it just makes sense to bring Jimmy here to help with [pitching coach] Darren [Balsley], to help [bullpen catcher Justin Hatcher] as we move through the rest of the year," Padres manager Bud Black said.
"With the influx of new pitchers on the roster and potentially more guys as the season goes, Jimmy has been with these guys a lot in the Minor Leagues. It's another set of eyes who have seen our players and another set of pitching eyes to help Darren, just like Ak and Darren have worked together over the last 10 years."
Black spoke to Akerfelds last week.
"He's been battling this head-on with a great deal of will, determination, character, fight," Black said.
Luebke debating elbow surgery
SAN DIEGO -- Padres starting pitcher Cory Luebke said a doctor's exam showed a partial tear of his ulnar collateral ligament in his left elbow, and he is deciding whether to undergo surgery or try pitching with the tear.
Luebke said he will reach a decision soon, possibly in a few days. He is two weeks into a possible six-week rehabilitation period if he opts to try pitching with the partial tear.
"We're trying to weigh our options and make the right decision," Luebke said.
If Luebke continues to rehab and he is unable to pitch with the tear, he acknowledged he would feel those several weeks were "wasted" because that would push back his return next season from possible Tommy John surgery. Recovery from that surgery typically takes a year. He has been on the disabled list since May 2, retroactive to April 28.
"Every day I miss now is a day next season," Luebke said. "The thought of risking six, seven, eight weeks here trying to get ready for this season is scary for me. That's six to eight weeks of next season you've got to take off from the get-go."
Luebke visited specialist Dr. Lewis Yocum last week for a second opinion, and the exam confirmed the partial tear. The decision whether to have surgery or wait and try to pitch is a group decision, Luebke said.
"You've got to explore all the options, and if it comes down to the two options of surgery or no surgery, you've got to make sure you're all in when you decide which way to go," Padres manager Bud Black said. "Cory is working through a big decision. His case is not clear cut."
Quentin's rehab progress slowed
SAN DIEGO -- Padres outfielder and cleanup hitter Carlos Quentin has been slowed in his rehabilitation for his knee injury, manager Bud Black said. Quentin is not currently playing in rehab games and he received a cortisone shot for his right knee on Tuesday.
After waiting 48 hours after the cortisone shot was administered, Quentin could resume baseball activities Thursday and Friday, Black said. The Padres will then reevaluate his schedule for playing in games.
"He will play. I'm not sure when," Black said. "He will play when he's able to play. After Friday night's game, we might have more of a clear picture of where his rehab might be headed."
Quentin last played in a game on May 10 in a rehab outing with High Class A Lake Elsinore. He has been on the disabled list the entire season after undergoing right knee surgery on March 19.
"I think he's got a little bit of soreness. I think there has been some inflammation, so I think the cortisone injection helps both those conditions," Black said. "He's anxious. He's champing at the bit to play. He's a very competitive guy. He wants to get out there."
• Padres pitching prospects Robbie Erlin (tendinitis) and Juan Oramas (forearm tightness) have landed on Double-A San Antonio's seven-day disabled list. Each is expected to miss one start.
• Starting pitcher Joe Wieland is doing "fine" and is expected to start playing catch in the next few days, Padres manager Bud Black said. Wieland went on the DL on May 10 (retroactive to May 7) for a strained right elbow.
• Outfielder Mark Kotsay said Wednesday he is feeling better and making progress every day after experiencing tightness in his lower back last weekend. He was listed as available off the bench for Wednesday's game against the Dodgers.
