The Pirates starter missed a month with a right calf strain.
The Pirates have activated A.J. Burnett from the DL and sent Ryan Reid to their Triple-A affiliate in Indianapolis, the team announced via Twitter.
Burnett is returning from a right calf strain, which he suffered in early-June. He will rejoin a rotation that also consists of Jeff Locke, Gerrit Cole, Charlie Morton and Francisco Liriano.
Reid, 28, has thrown 11 innings so far in 2013, and has a 7/3 K/BB ratio and an ERA of 1.64.
Burnett has an ERA of 3.12 in 89⅓ innings pitched this season for the Pirates, who are currently in first place in the National League Central. They have had success this season through excellent pitching, and getting Burnett healthy will only help to bolster that.
Burnett's return also comes as a reminder that the team will have to make a decision on Gerrit Cole soon. The Pirates might choose to send him back to Triple-A when starting pitchers James McDonald and Wandy Rodriguez come off the DL.
