Putnam (elbow) has been throwing from 120 feet and plans to throw off a mound Saturday, Scott Merkin of MLB.com reports.
Putnam continues a steady progression recovering from elbow soreness, as he threw from 60 feet last week and has now advanced to 120 feet with no problems. If he continues to report no issues this upcoming week then he'll likely throw off a mound on Saturday. The 29-year-old has been one of the White Sox most consistent relievers, giving up more than one earned run in only one appearance this season while maintaining a 2.30 ERA over 27.1 frames.
