Positive response from Padres regarding sale

ATLANTA -- Third baseman Chase Headley, currently the longest-tenured Padres' player, was pleased to hear the news Thursday that Major League Baseball approved the sale of the team.

"I think it is great news. We haven't had a chance to meet any of the new owners yet, but everything I've heard has been good," Headley said. "It's nice to have some stability and closure to this. I think it bodes well for the future."

The sale of the Padres from John Moores to the group led by the Seidler/O'Malley families and longtime San Diego businessman Ron Fowler was approved during baseball's quarterly meetings in Denver.

"It sounds very positive," said San Diego assistant general manager A.J. Hinch, who is traveling with the team on this road trip. "Everything is headed in the right direction. We'll wait for further information."

Fowler is the club's new control person and will represent the organization at league meetings. Former Dodgers owner Peter O'Malley's son Kevin and nephew Peter Seidler will represent the family in a group that also includes professional golfer Phil Mickelson, a San Diego native.

"I think it's a great day for the Padres, a great day for the organization and a great day for the city," said Padres manager Bud Black. "I think the Seidler family, the O'Malley family, Ron Fowler, these guys who are coming onboard ... it's fantastic. It's the start of an era of new ownership. I think it's a great thing."

The Padres won't hold a news conference to announce the new ownership group until the final closing of the sale, which will occur on or before Aug. 31.

Headley took it as an encouraging sign that the new ownership group gave general manager Josh Byrnes approval to sign outfielder Carlos Quentin to a three-year deal worth $27 and closer Huston Street to a two-year deal for $14 million in July.

"It is very good news that they signed off on those big deals," said Headley, who made his debut with the team in 2007.

Stauffer returns to San Diego after rehab setback

ATLANTA -- Pitcher Tim Stauffer, working his way back from a strained right elbow, has had a setback in his rehabilitation and has returned to San Diego.

Stauffer was scheduled to start Thursday's game for Tucson. But earlier this week, Stauffer started to experience soreness in his right shoulder. He has since returned to San Diego to be examined.

Stauffer allowed two runs on four hits in three innings of his first and only outing with Triple-A Tucson on Aug. 11.

Stauffer was in line to start Opening Day until the final week of Spring Training when he first started to feel discomfort in his elbow. He started the season on the disabled list, but he was activated on May 14 in time for a start in Washington.

Stauffer experienced soreness in his elbow -- in his flexor tendon bundle -- late in that outing against the Nationals. He allowed four runs (three earned) in five innings in that game and eventually landed on the disabled list again on May 18, retroactive to May 15.

Black has chance to evaluate evolving bullpen

ATLANTA -- Bullpen consistency has been a staple of manager Bud Black's teams since he took over prior to the 2007 season, though there's been nothing constant about the personnel in this season's bullpen.

Case in point: Heading into Thursday's game against the Braves, only Luke Gregerson remains from the seven-man bullpen that began the season.

Five of the other six members -- Andrew Cashner, Anthony Bass, Micah Owings, Huston Street and Joe Thatcher -- are all currently on the disabled list. The other, Ernesto Frieri, was traded to the Angels in May.

"Our bullpen has been through major changes in personnel based on a number of factors," said Black. "... Injuries, performance and relievers becoming starters."

In addition to Gregerson, the current bullpen consists of rookies Miles Mikolas, Tom Layne, Brad Brach, Dale Thayer, Cory Burns and Brad Boxberger. Everyone one of those pitchers started the season in the Minor Leagues.

"The names now are a lot different than we anticipated," Black said. "But it gives us an opportunity to see what we've got moving forward."

Short hops

• Rookie catcher Yasmani Grandal started his Minor League rehabilitation assignment on Wednesday with Class A Lake Elsinore. Grandal went 0-for-4 with three strikeouts as the designated hitter. On Thursday, Grandal will catch for the Storm. No determination has been made on how many more games -- if any -- he will play in the Minor Leagues before he's reinstated from the disabled list.
