Irvin won't start Tuesday's series opener in Houston and will instead have his next turn in the rotation skipped, Bobby Blanco of MASNSports.com reports.

EDGE Analysis

Washington will take advantage of Monday's off day to move up at least three of their other four starters while pushing Irvin to the back of the schedule. Patrick Corbin, Josiah Gray and MacKenzie Gore will all pick up starts in Houston, leaving Irvin's next start to come either Friday or Saturday versus the Marlins in Washington. According to Andrew Golden of The Washington Post, manager Dave Martinez said that pushing Irvin's next start back will allow the rookie right-hander to make some mechanical adjustments in bullpen sessions.

Irvin did not factor into the decision Tuesday, allowing four runs on five hits and three walks over four innings against Arizona. He struck out one.

EDGE Analysis

After bursting onto the scene with one run allowed across his first two starts (10.2 innings), Irvin has slowed up considerably, piling up three losses with an 8.85 ERA and a 15:13 K/BB over 20.1 innings (five starts) since. Though he has matched up against some powerful offenses in the Mets, Padres and Dodgers over that five start stretch, Irvin hasn't shown much to give managers hope for a turnaround. He is lined up for another tough start on the road against Atlanta this weekend.

Irvin (1-3) took the loss Tuesday versus the Dodgers, allowing four runs on eight hits and a walk while striking out three over five innings.

EDGE Analysis

Irvin contained his struggles to the second and third innings, but the damage was too much for the Nationals to overcome. He's lost three of his last four outings, and this was just the second time in six starts Irvin's been able to finish five frames. He's at a 5.67 ERA, 1.63 WHIP and 22:17 K:BB through 27 innings. With a 5.7 BB/9 and four home runs surrendered in his last three appearances, there's not much to like with the right-hander. He's projected for a home start versus the Diamondbacks in his next outing.

Irvin did not factor into the decision Thursday, allowing two runs on two hits and four walks over 4 innings against San Diego. He struck out four.

EDGE Analysis

It's a step in the right direction for Irvin after he allowed 10 runs in 7.1 innings over his previous two outings. Still, the rookie right-hander only made it through four innings after throwing 76 pitches. Irvin is 1-2 with a 5.32 ERA, 1.59 WHIP and 19:16 K:BB through his first five major-league starts (22 innings).

Irvin (1-2) took the loss Friday, coughing up six runs (four earned) on five hits and four walks over 2.2 innings as the Nationals were downed 8-6 by the Tigers. He struck out one.

EDGE Analysis

It was a brutal outing for the rookie right-hander, who served up two homers to a light-hitting Detroit lineup that wound up going yard four times in total on the night. Irvin now carries a 5.50 ERA, 1.61 WHIP and 15:12 K:BB through 18 innings over his first four big-league starts, but the Nats don't have any clearly better rotation options in the minors. If he gets another turn, it will likely come at home next week against the Padres.

Irvin (1-0) earned the win Monday, allowing four hits and three walks over 6.1 scoreless innings in a 5-1 win over the Giants. He struck out five.

EDGE Analysis

Irvin has now allowed just one run over 10.2 innings this year. The rookie has started his big league career off well after spending four and a half years working up the ranks in Washington's farm system. However, this is a very small sample size, and fantasy managers would be better off watching him develop a bit more before fully trusting him.

Irvin is scheduled to start Monday's game against the Giants at Oracle Park, Mark Zuckerman of MASNSports.com reports.

EDGE Analysis

After limiting the Cubs to one earned run on two hits and four walks over 4.1 innings in a no-decision in his MLB debut last Wednesday, Irvin will be rewarded with at least one more turn through the rotation. Whether he sticks with the Nationals beyond Monday's outing will likely hinge on how he performs in San Francisco. If he does acquit himself well against the Giants, Irvin would likely line up for two-start week, with his second outing likely to come next Sunday versus the Mets in Washington, D.C.

Nationals manager Dave Martinez said Thursday that Irvin will stay on the major-league roster for now, Bobby Blanco of MASNSports.com reports.

EDGE Analysis

Martinez wouldn't fully commit to Irvin getting another start after he made his MLB debut Wednesday, but the 26-year-old right-hander probably earned it after delivering 4.1 innings of one-run ball versus the Cubs. If the Nats stay on turn and Irvin does indeed remain a normal part of the rotation, his second major-league outing would likely be on the road early next week in San Francisco.

Irvin did not factor into the decision Wednesday, allowing one run on two hits and four walks across 4.1 innings during a 2-1 win over the Cubs. He struck out three.

EDGE Analysis

Irvin was recalled from Triple-A Rochester on Wednesday and replaced Chad Kuhl (foot) in the Nationals' starting rotation. The rookie struggled to find his command early, plunking Nico Hoerner and walking Ian Happ before surrendering a two-out, RBI single to Seiya Suzuki in the first inning. However, that was the only blemish on the night for Irving, who was replaced in the fifth with one out and runners on first and second. The four walks were a bit concerning for the 26-year-old, who posted a 1.54 WHIP over 22.1 innings at Triple-A, but he likely did enough in his MLB debut to earn at least one more start while Kuhl is on the 15-day injured list.

The Nationals recalled Irvin from Triple-A Rochester ahead of his scheduled start Wednesday against the Cubs.

EDGE Analysis

Just as manager Dave Martinez said would be the case following Tuesday's 4-1 win over the Cubs, Irvin will step into the rotation Wednesday for what will be his MLB debut. The 26-year-old right-hander supplied a 5.64 ERA and 1.54 WHIP while striking out 20 over 22.1 innings at Rochester, but he could nonetheless have a chance to stick around as the Nationals' No. 5 starter with a solid showing against the Cubs.
