Pirates pitcher Gerrit Cole threw 84 pitches during a six-inning simulated game Monday, and manager Clint Hurdle said the throwing session went well, MLB.com reports.

"I thought it went very well," Hurdle said. "The volume of work -- six ups, 84 pitches. Threw his two-seamer, his four-seamer, his curveball -- probably more than his slider -- his changeup was good, the finish to his fastball was firm and solid. We'll see how he feels tomorrow, but I thought it was a very good next challenge that, from at least the perspective of today, he was able to meet and do well with."

Cole could possibly return from the disabled list in time to start Saturday's game, but the team has yet to set the weekend rotation. He's working his way back from shoulder fatigue.
