After a successful bullpen session on Wednesday, Marcum threw 30 pitches on Sunday. He said he was pleased with his ability to locate his pitches, and felt fine physically.
"You can only do so much in bullpens," Marcum said. "So it's nice to get out there and get up and down, see some hitters in the box. That way you can tell how they're reacting to pitches and how the ball's coming out."
Marcum will play catch on Monday, and will make plans to potentially begin a Minor League rehab stint, depending on how his elbow feels. Marcum said he felt no soreness on Sunday, and doesn't anticipate any ensuing pain or tightness on Monday.
Marcum hopes to begin a rehab assignment on Thursday, and expects that two appearances in the Minors would be enough before making a return to the Brewers' rotation. Marcum was placed on the 15-day disabled list on June 23, retroactive to June 15, and transferred to the 60-day DL on July 29.
Marcum last started a game on June 14 against Kansas City, allowing two runs on four hits over 7 2/3 innings. He was 3-0 with a 2.30 ERA in four starts prior to heading to the DL.
