The Atlanta Braves have placed right-hander Tommy Hanson on the 15-day disabled list with a lower-back strain, reports Mark Bowman and Teddy Cahill of MLB.com:

After watching Tommy Hanson struggle through a third consecutive start on Monday night, the Braves were leaning toward giving him a couple extra days of rest before his next outing. But they have instead opted to place him on the 15-day disabled list with a lower-back strain.

Hanson isn’t concerned with the injury, calling it "not a big deal." The 25-year-old said he just needs to "get it right for the rest of the season."

So far this year, Hanson has posted an ERA and WHIP of 4.29 and 1.444 with 8.1 SO/9 and 3.9 BB/9 over 22 starts. His numbers were a bit inflated by his poor month of July (6.21 ERA) which prompted the Braves to place him on the DL.

26-year-old right-hander Kris Medlen is expected to take Hanson’s spot in the Braves’ rotation. He has appeared in 38 games for Atlanta this season, all in relief, and has maintained an ERA and WHIP of 2.48 and 1.086.
