Hellickson (hamstring) threw a bullpen session Monday, Chelsea Janes of The Washington Post reports.

EDGE Analysis

It was Hellickson's second bullpen session since landing on the disabled list with a hamstring injury near the start of June. The right-hander also did some fielding and covered the bases with no issues. The expectation is that Hellickson will be reevaluated in the coming days before the Nationals determine the next step in his rehab.
