Ross (shoulder) will make a rehab start on Sunday, Dan Kolko of MASN reports.

EDGE Analysis

If all goes well for Ross in his rehab start, he could rejoin the Nationals rotation next Saturday against the Giants. Ross has been on the disabled list since July 3 with shoulder inflammation.

Nationals manager Dusty Baker said that Ross will make a rehab start, which would rule him out to start on Sunday, Chelsea Janes of the Washington Post reports.

EDGE Analysis

At this time it's unclear when or where this rehab outing will take place. If all goes well in his start, Ross is in line to return at some point next week. Lucas Giolito looks like the clear favorite to start for the Nationals on Sunday.

Ross (shoulder) threw a simulated game at Nationals park on Tuesday, Jamal Collier of MLB.com reports.

EDGE Analysis

Ross has been sidelined since early July with shoulder inflammation but has proceeded through his rehab with no setbacks so far. He began throwing off flat ground several weeks ago, took part in pregame drills Friday, and has now taken another step forward by tossing a simulated game. It's unclear whether he'll require a rehab assignment but he appears near the tail-end of his DL stint.

Ross (shoulder) threw a simulated game Tuesday afternoon, Jamal Collier of MLB.com reports.

EDGE Analysis

Ross continues to work his way back into form while nursing some inflammation in his throwing shoulder. The right-hander remains without a definitive return timeline, and at this point it's unclear if the Nats plan to send him out on a rehab assignment. The most likely scenario would likely be a couple of bullpen sessions, though the team will certainly exercise caution.

Ross (shoulder) took part in pre-game drills Friday and will likely throw a bullpen session this weekend, The Washington Post reports. "I'm feeling better," Ross said. "Feels like everyday, I'm feeling a little stronger. I don't know exactly what the plan is yet - still have a couple days before I can come back."

EDGE Analysis

The Nats don't need a fifth starter until next weekend's home series against the Padres, which should give Ross enough time to throw a couple of bullpens prior to coming off the DL. If he has any kind of setback though, or the team decides he needs a minor league rehab assignment, Lucas Giolito would likely be called back up instead for another spot start or two.

Ross (shoulder) threw off flat ground Saturday prior to Washington's game against the Mets, Bill Ladson of MLB.com reports. The right-hander was placed on the disabled list last Sunday, one day after he experienced reduced velocity.

EDGE Analysis

Nationals pitching coach Mike Maddux was on hand for the session and indicated Ross was "throwing free and easy." Ross will throw a bullpen session during the All-Star break and hopefully, according to manager Dusty Baker, will be able to pitch when Washington next needs a fifth starter, July 22 at home against the Padres.

An MRI on Sunday morning revealed the shoulder inflammation that led to Ross getting placed on the DL, Chelsea Janes of the Washington Post reports.

EDGE Analysis

Ross will effectively be held out through the All-Star break, with top prospect Lucas Giolito in line to take over his spot in the rotation on a temporary basis. The Nationals will likely be careful with Giolito's innings this season, so look for Ross to claim back his rotation spot once he returns. Shoulder issues can be tricky, however, so fantasy owners considering a trade involving either of these players should keep a close eye on the situation.

Ross has been placed on the 15-day DL due to right shoulder inflammation, Dan Kolko of MASN Sports reports.

EDGE Analysis

Ross suffered a noteworthy drop in velocity during Saturday's start, and it now appears that some shoulder inflammation was the culprit. The team will take a conservative approach by putting the right-hander on the DL, a move that also freed up a roster spot for Sunday's starter, Stephen Strasburg. There has been little indication of a serious ailment in play, but the team is unlikely to update his condition until after the All Star break. Ross will first be eligible to return July 17.

Ross experienced a noteworthy drop in velocity during his start against the Reds on Saturday, CSN Mid-Atlantic reports.

EDGE Analysis

Ross was hit around a bit in the early parts of Saturday's start, but at that time, his velocity remained normal, with his fastball topping out at 94-95 MPH during the first few innings. As his start came to a close, however, his fastball velocity was regularly 90 MPH or below. The right-hander averaged 93.4 MPH on his fastball heading into Saturday's start, so the sudden decrease has forced the Nationals to examine whether or not there is an injury in play. The 23-year-old doesn't believe he is injured, but the Nationals will take every precaution to see if they can get his velocity numbers back on track for his next scheduled start Thursday.

Ross allowed four runs on 10 hits, struck out two and walked none over 5.1 innings in a no-decision against the Reds on Saturday.

EDGE Analysis

He was in trouble the first three innings of the game, but Ross worked out of a pickle in the third and then retired seven of the last 10 batters he faced. He's allowed exactly four runs and 10 hits in each of his last two starts, but Ross still has respectable numbers with a 7-4 record, 3.49 ERA, 1.26 WHIP and 79 strikeouts in 95.1 innings. His next start will be Thursday against the Mets.
