CHICAGO -- Braves manager Fredi Gonzalez is expecting Julio Teheran and Randall Delgado to be among the players added to the Braves' Major League roster in September. But the two highly regarded pitching prospects might have to wait until Triple-A Gwinnett's season is complete.

"You'd like to get those guys experience," Gonzalez said of the two young right-handed pitchers who have both started their Major League careers with a pair of spot starts this year.

There is a chance either Teheran or Delgado could make a start in September, if necessary, or to possibly provide rest to one of the regular rotation members down the stretch. But they would likely be primarily utilized out of the Braves' bullpen.

The Braves have already bolstered their bullpen with Arodys Vizcaino, and filled a void in their rotation with Mike Minor. Teheran, Vizcaino, Delgado and Minor stand as the club's top four pitching prospects, and it appears each could be in the Majors as Atlanta attempts to clinch a second consecutive playoff appearance in September.

Along with Teheran and Delgado, the Braves are expected to also add right-handed reliever Anthony Varvaro and backup catcher J.C. Boscan to their Major League roster once Gwinnett's season concludes.

Hanson throws off mound in Chicago

CHICAGO -- With the Braves holding a comfortable lead in the National League Wild Card race and Mike Minor pitching well in his place, Tommy Hanson knows he can comfortably rest his ailing shoulder longer than he did in June. But the 24-year-old pitcher admits the recent inactivity has proven frustrating.

Hanson opted to throw about 10 pitches during a short bullpen session at Wrigley Field on Monday. He plans to return to the bullpen mound Tuesday to throw a longer bullpen session that will truly test his shoulder, and give the Braves a better idea of whether Hanson is ready to make his scheduled rehab start for Triple-A Gwinnett on Saturday.

"I just wanted to get off the mound and feel that slope again," Hanson said. "I just wanted to try to get loose today."

If anything could truly be gathered from the short session, Hanson did at least say he felt good. This was the first time he threw off a mound since lasting 3 1/3 innings and allowing seven earned runs against the Mets on Aug. 6. When an MRI exam performed a few days later showed no structural damage, he was diagnosed with right shoulder tendinitis for the second time in two months.

Hanson missed just two weeks with the ailment in June, and when he returned from the disabled list to face the Mariners on June 28, he was still feeling tightness. He has posted an 8.10 ERA and allowed opponents to hit .313 against him in five starts since the All-Star break.

Minor will start in Hanson's spot Tuesday, and likely make at least one more start Sunday afternoon against the Mets.

"Everyone has been throwing well, so it's not like there is a big rush for me to get back out there," Hanson said. "Obviously, I want to get back out there as soon as possible. I'm tired of sitting around and I'm itching to get back out there."

Moylan gets first game action for Gwinnett

CHICAGO -- After anxiously waiting for the chance to pitch in a game again, Braves right-handed reliever Peter Moylan returned to the mound Monday night and tossed a scoreless inning for Triple-A Gwinnett.

Facing the Charlotte Knights, Moylan allowed a single and pitched around a two-out walk. More importantly, he exited the 18-pitch inning without any discomfort. This marked the first time he had pitched in a game setting since he began experiencing back pain in the middle of April.

"It wasn't pretty, but it was effective, " Moylan said via text message.

Since undergoing a surgical procedure to repair a herniated disc on May 17, Moylan has experienced a long rehab process. He underwent similar surgical procedures in 2001 and 2003, while he was selling insurance and playing club baseball in his native Australia.

Moylan is scheduled to pitch again for Gwinnett on Thursday and then make back-to-back appearances within the following few days. He is not expected to be activated from the disabled list until the Major League rosters expand in September.

Johnson Sr.'s life to be celebrated Wednesday
