EDGE Analysis

Hellickson will take the next step in his rehab after getting through a pair of bullpen sessions and some fielding drills with no issues. The Nationals will reevaluate him following Tuesday's simulated outing, after which a more concrete return date should come into focus. If all goes well, the 31-year-old could potentially return over the weekend. Hellickson has been sidelined since June 5 with a strained hamstring.
