"I'm happy, it went well," Hanson said after the Braves' 6-3 loss to the Cardinals.
If Hanson does not experience any soreness on Monday, he will push forward. He is expected to throw a slightly longer session on Tuesday. If all goes well, a trip to the Instructional League would be the next step.
Atlanta manager Fredi Gonzalez would like for Hanson to get at least one regular-season start under his belt before postseason play.
His ERA stood at 2.44 on July 9 before he endured a stretch of 24 runs in 26 2/3 innings.
Hanson was somewhat concerned entering Sunday's workout, but he came out with a positive attitude.
"I was nervous, I didn't know what was going to happen," he said.
