Tillman (shoulder) threw on flat ground Thursday and remains on track to start Saturday's game against the Astros, Rich Dubroff of CSN Mid Atlantic reports.

EDGE Analysis

It was reported earlier in the week that Tillman would likely return Saturday, and Thursday's news only adds more credence to that notion. Barring some sort of setback, expect to see Tillman back on the mound Saturday in what will be his first start since August 11. The right-hander holds a 3.58 ERA since the All-Star break.
