Ross Detwiler was serviceable in his return from the disabled list Thursday, allowing three runs over five frames in a 5-4 win over the Rockies.

Detwiler gave up six hits, hit a batter, didn't walk anyone and struck out a pair. Not quite fully stretched out, he was removed after throwing 77 pitches. The left-hander now has a 3.03 ERA for the season, but it's come along with a 1.42 WHIP and just 25 strikeouts over 50 2/3 innings. He'll face the Phillies on the road next.

Nationals activated LHP Ross Detwiler from the 15-day disabled list.

Detwiler wound up missing four weeks with a right oblique strain. He will return to the Nationals' starting rotation on Thursday to face the Rockies at Coors Field. That's not appealing fantasy matchup, but the 27-year-old lefty owns a 2.76 ERA in 45 2/3 innings this season and remains a decent streaming option in mixed leagues.

Ross Detwiler (oblique) is expected to be activated from the disabled list to start on Thursday in Colorado.

Detwiler felt fine during a rehab assignment over the weekend and is ready to rejoin the rotation. His pitch count might be a bit limited initially, and that, combined with the fact that he's starting in Colorado, makes him a sketchy fantasy play out of the gate.

After a successful rehab outing at High-A Potomac on Saturday, Ross Detwiler said he felt good enough to return to the Nationals' rotation on Thursday.

Detwiler tossed 3 2/3 innings in the game allowing one run on seven hits (all singles). He struck out four without walking a batter. While he feels great, the Nationals may opt to have him make one more rehab start before rejoining the rotation.

Ross Detwiler (oblique) will make a minor league rehab start Saturday with High-A Potomac.

Detwiler is slated to throw around 80 pitches. If all goes well, he should be activated to start against the Rockies or Indians late next week. The 27-year-old left-hander has been sidelined since May 16 with a strained oblique.

Ross Detwiler (oblique) is expected to make one rehab start before rejoining the Nationals' rotation.

Manager Davey Johnson said Detwiler "threw the heck out of the ball" in his bullpen session on Wednesday, but they're not ready to throw him into the rotation just yet. Ross Ohlendorf will get a shot on Saturday in place of Stephen Strasburg (lat) before likely giving way to Detwiler next week.

Ross Detwiler (oblique) could be activated from the disabled list Saturday.

Detwiler, out since May 16, is a candidate to start Saturday against the Twins if Stephen Strasburg lands on the DL. The Nationals also haven't ruled out sending him on a rehab assignment before he returns.

Ross Detwiler (oblique) is expected to begin throwing off a mound in four days.

Detwiler has been on the disabled list since May 16 with an oblique injury. If everything goes smoothly, he should be back in the Nats' rotation by mid-June.

Ross Detwiler (oblique) remains shut down from any activity.

Detwiler felt tightness in his right oblique as he fielded grounders from the mound during practice Sunday, which forced him to the DL. The Nationals will give another start to Nate Karns this weekend, and it's unclear how long Detwiler will be out. "I was kinda doing the [fielding drills] and I felt something there," Detwiler said. "We kinda talked about it. It's too early in the season to push through it and don't want to deal with this for the next four or five months."

Nationals placed LHP Ross Detwiler on the 15-day disabled list, retroactive to May 16, with an oblique injury.

Detwiler threw a bullpen session Saturday and was expected to start Tuesday against the Orioles, but is now dealing with a setback. The Nationals have yet to name who will take his spot in the starting rotation, but left-hander Xavier Cedeno has been called up to replace Detwiler on the active roster.
