Braves recall Delgado to help tired bullpen

ATLANTA -- After needing to use their bullpen for seven innings during Sunday night's win over the Phillies, the Braves opted to promote Randall Delgado from Triple-A Gwinnett one day earlier than expected.

Delgado arrived at Turner Field in time to be available to pitch out of the bullpen if necessary on Monday. The Braves are expected to promote two more pitchers once Gwinnett concludes its season on Monday. The likely candidates are Julio Teheran and Cory Gearrin.

Delgado went 4-9 with a 4.42 ERA in 17 starts for the Braves this season. Since being sent to Triple-A Gwinnett in late July, the 22-year-old right-hander has worked on gaining more consistency with his delivery.

The Braves could use Delgado as a reliever or possibly in a starting role if Tommy Hanson would continue to struggle. Ben Sheets, who is on the disabled list with right shoulder inflammation, is at least a week away from being able to start preparing for another potential start.

McCann gets day off after receiving cortisone shot

ATLANTA -- Brian McCann missed a second straight start on Monday as he allowed his shoulder to gain the necessary rest after receiving another cortisone injection on Saturday night.

McCann did not gain the immediate relief that he was hoping to receive after getting a cortisone injection on Aug. 7. But with less than a month left in the season, the All-Star catcher is hoping that this latest shot will help him provide the kind of production that was lacking during a frustrating August.

"His at-bats are good, but it's bothering him," Gonzalez said of McCann's shoulder, which has been bothered by a cyst and some fraying around the labrum.

The Braves are hoping McCann might return to the lineup as early as Tuesday. Backup catcher David Ross, who has been dealing with some discomfort around his left oblique muscle, made his second straight start during Monday's series opener against the Rockies. McCann has batted .228 with 18 home runs and a .702 OPS in 104 games this season. It appeared he might have righted himself when he batted .296 with nine home runs and a 1.059 OPS in July. But he then batted .181 without an extra-base hit in August.

McCann's shoulder has plagued him most of this season. While it has not affected him from a defensive standpoint, it has limited his extension with some of his swings.
