Hellickson (hamstring) felt fine after making a rehab start Sunday and believes he is ready to rejoin the Nationals' rotation, Dan Kolko of MASN Sports reports.

EDGE Analysis

While Hellickson is optimistic about making his next start with the Nationals, it should be noted he was tagged for 11 earned runs over just 4.2 innings during Sunday's outing. Hellickson noted he felt strong Sunday, but he also noted his command was off and teams do not typically activate players after outings like that, so it would hardly be surprising if he makes at least one more start in the minors before rejoining the big club.

Hellickson (hamstring) will make a rehab start for High-A Potomoc on Sunday, Jorge Castillo of The Washington Post reports.

EDGE Analysis

The right-hander is set to throw about 85 pitches, putting him on track to rejoin the Nationals' rotation as soon as Friday against the Phillies. Hellickson made nine starts this season before straining his hamstring, posting an outstanding 2.28 ERA and 0.92 WHIP with a 34:6 K:BB through 43.1 innings.

Hellickson (hamstring) will pitch in a minor-league game this weekend, Jorge Castillo of The Washington Post reports.

EDGE Analysis

Hellickson will likely only need the one rehab assignment after tossing a simulated game Tuesday. If all goes well this weekend, expect to see Hellickson back in the Nationals' rotation for the series against Philadelphia from June 29 through July 1.

Manager Davey Martinez said Hellickson (hamstring) will throw a simulated game Tuesday, Dan Kolko of MASN Sports reports.

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.

Hellickson (hamstring) fielded grounders and covered the bases with no issues Monday, Mark Zuckerman of MASN Sports reports.

EDGE Analysis

Hellickson threw a pair of successful bullpen sessions Thursday and Saturday, and the right-hander suggested that Monday's workout was "probably the last step." If Hellickson doesn't need a rehab start -- as he suggests -- he could rejoin the big-league rotation as early as Tuesday, though nothing has been confirmed at this point. The 31-year-old compiled a 2.28 ERA across nine starts prior to landing on the disabled list near the start of June.

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.

Hellickson (hamstring) has done very light throwing, Dan Kolko of MASN Sports reports.

EDGE Analysis

Hellickson has made little progress since landing on the disabled list near the start of June with a hamstring injury. The right-hander is still working on strengthening his hamstring and has yet to resume a throwing program, leaving his potential return date fuzzy.

Hellickson (hamstring) was placed on the 10-day disabled list Tuesday, Chelsea Janes of The Washington Post reports.

EDGE Analysis

Hellickson exited his previous start with a hamstring injury after facing just two hitters, and a subsequent MRI determined the issue is serious enough to require a stint on the disabled list. This is a tough break for the Nationals and Hellickson, as the 31-year-old had compiled a solid 2.28 and 0.92 WHIP across nine starts (43.1 innings) prior to suffering the injury. The veteran will be eligible to return June 15, though it's unclear if he'll be ready by then. In the meantime, with four off days over the next two weeks, the Nationals could get by with a four-man rotation until June 19 if they choose.

Hellickson will undergo an MRI on Monday to determine the extent of the right hamstring injury he suffered during Sunday's 4-2 loss to the Braves, Mark Zuckerman of MASN Sports reports.

EDGE Analysis

Hellickson faced just two hitters before departing Sunday when he pulled his hamstring after attempting to snag a high throw from Nationals first baseman Mark Reynolds. The right-hander expressed optimism after the contest that the injury wasn't a significant one, but a timeline for his return -- as well as a decision on a disabled-list stint -- likely won't be known until after the MRI results are read. With four off days over the next two weeks, the Nationals could get by with a four-man rotation until June 19 in the event Hellickson requires some time off.

Hellickson was removed from Sunday's game against the Braves after suffering an apparent right hamstring injury in the first inning, Jamal Collier of MLB.com reports.

EDGE Analysis

Hellickson was able to record just one out Sunday as he appeared to strain his right hamstring while running to cover first base on a groundball hit by Ozzie Albies. The Nationals haven't revealed the specifics of the injury, but it sure appeared to be of the strained hamstring variety, which would undoubtedly require a trip to the disabled list. The recently-recalled Jefry Rodriguez was summoned in relief following Hellickson's removal. We'll await word of his official diagnosis.
