Ross was called up from Triple-A Fresno on Sunday, Jamal Collier of MLB.com reports.

EDGE Analysis

Ross was moved into a bullpen role in spring training and rejoins the team with the Nationals in need of fresh arms. The 25-year-old could serve in a variety of roles given the massive early season struggles of Washington's bullpen.

Ross was optioned to Triple-A Fresno on Saturday, Pete Abraham of The Boston Globe reports.

EDGE Analysis

Ross had a strong spring, recording a 2.53 ERA and a 10:3 K:BB in 10.2 spring innings. Despite that performance, he wound up the odd man out in the Nationals' rotation. He could be the first one called on if an injury strikes one of the team's top five starters.

Ross is being considered for a switch to the bullpen, Jesse Dougherty of The Washington Post reports.

EDGE Analysis

The Nats' current projected big-league bullpen doesn't feature a true long reliever, which could be a problem if Jeremy Hellickson is strictly limited to pitching only twice through the order -- potentially opening the door for Ross to make the 25-man roster. The right-hander is still being stretched out as a starter for now -- he got his first start of the spring in a split-squad game Monday, tossing 61 pitches over three innings -- and he'll probably begin the season in the rotation for Triple-A Fresno, but if he struggles in the PCL, Ross could find himself moved to a relief role for good.

Ross threw 53 pitches in Wednesday's game against the Astros, Jesse Dougherty of The Washington Post reports.

EDGE Analysis

Making his second appearance of the spring, the right-hander racked up that pitch count in only 1.2 innings thanks to some shoddy defense behind him, but Nats manager Dave Martinez thought Ross' slider looked sharp and the location on his fastball was pretty good. "He's been throwing quite a bit, and [pitching coach Derek Lilliquist] said, 'He's good for 50 pitches today, just let him go out there,' " Martinez said. "I mean he should have gotten out of the inning, we made an error. He threw well." Ross, who threw only 41 innings last season between the majors and minors after rehabbing from Tommy John surgery, figures to begin the season at Triple-A Fresno, but a strong beginning to the campaign would have him first in line for a promotion when injuries hit the Nats rotation.

Ross is behind Jeremy Hellickson in the battle for the Nationals' fifth starter job and is expected to open in the minors, Brittany Ghiroli of The Athletic reports.

EDGE Analysis

Ross returned from Tommy John surgery to make three starts last season but didn't post impressive numbers, striking out just seven batters while allowing nine earned runs in 16 innings. He could crack the roster in a long-relief role but is more likely to open the year in the rotation at Triple-A Fresno.

Ross signed a one-year, $1 million contract with the Nationals on Thursday, avoiding arbitration, Robert Murray of The Athletic reports.

EDGE Analysis

Ross spent most of the season recovering from Tommy John surgery. He returned in mid-September and struggled across a trio of starts, allowing 10 runs (nine earned) while posting a 7:4 K:BB across 16 innings. The 25-year-old will enter spring training with the inside track on a rotation spot.

Ross (0-2) took the loss Friday, giving up four runs on five hits -- including three home runs -- and a walk over five innings while striking out four as the Nationals fell 5-2 to the Rockies.

EDGE Analysis

The right-hander wasn't particularly impressive in three starts to close out the season, posting a 5.06 ERA and 7:4 K:BB in 16 innings, but ending the year in Coors Field can sour anyone's stat line. Ross will get the offseason to recover further from his Tommy John surgery, and he's expected to head into 2019 holding down a spot at the back of the Nats' rotation.

Ross threw five innings and took the no-decision Thursday, allowing two runs on four hits and two walks in the 4-3 loss to the Cubs.

EDGE Analysis

In his first MLB action since July of 2017, Ross turned in a decent outing despite failing to record a strikeout. He kept the Cubs scoreless through three innings before giving up two runs in the fourth. He'll look to take the mound again in Miami next Tuesday.

Ross has been confirmed as the Nationals' starting pitcher for Thursday's game against the Cubs.

EDGE Analysis

The Nationals endured no further rainouts after a postponement Monday resulted in Washington and Philadelphia playing a doubleheader Tuesday, so Ross will slot into the rotation Thursday for his first official start in the big leagues this season. After a lengthy recovery from Tommy John surgery, Ross was activated from the 60-day disabled list Sept. 4 and took the hill that same day against the Cubs, but he pitched only 1.2 innings before the contest was postponed due to inclement weather. Though his statistics were wiped out as a result, Ross looked good in the brief cameo, with his fastball even hitting 97 miles per hour on the radar gun. While the Nationals will probably monitor his pitch counts carefully during Thursday's start and any subsequent turns he makes, Ross could make for an interesting upside pickup in deeper leagues after he occasionally flashed signs of dominance prior to succumbing to the elbow injury in 2017.

Ross is tentatively scheduled to start Thursday against the Cubs, Chelsea Janes of The Washington Post reports.

EDGE Analysis

Ross rejoined the rotation last week, but his start -- which was his first since undergoing Tommy John surgery in July of 2017 -- was rained out after just 1.2 innings. The 25-year-old looked sharp prior to the postponement, hitting 97 mph with his fastball and allowing just one hit while striking out one. His next start is tentatively set for Thursday, though that could easily change with rain threatening the east coast all week.
