Mariners' Justin Dunn: Strikes out three as opener
by RotoWire Staff | RotoWire

Dunn issued one walk and struck out three batters over two shutout innings during Sunday's win over Oakland.

Dunn was used as the opener in all four of his MLB appearances this season and tossed two scoreless innings in three of those. He walked eight batters over his first 2.2 MLB innings but issued just one free pass over his last four frames. The 24-year-old ends the season with a 2.70 ERA.

Mariners' Justin Dunn: Gets job done as opener
by RotoWire Staff | RotoWire

Dunn tossed two scoreless frames as Seattle's opening pitcher and didn't factor into the decision in Tuesday's 3-0 loss to the Astros. He gave up a base hit and struck out one in the 27-pitch outing.

After a rough big-league debut Sept. 12 in which he walked five batters and failed to escape the first inning, Dunn has now kept the opposition off the board in back-to-back turns as opener. The rookie is scheduled to make his final appearance as an opener Sunday against Oakland, likely working in front of primary pitcher Tommy Milone in the contest.

Mariners' Justin Dunn: Filling opener role Tuesday
by RotoWire Staff | RotoWire

Dunn is slated to serve as the Mariners' opening pitcher in Tuesday's game against the Astros.

Dunn will pick up his third MLB start after tossing two shutout innings while opening in front of primary pitcher Tommy Milone on Sept. 18 in Pittsburgh. The rookie is likely in line for a two- or three-inning appearance Tuesday while Milone covers the bulk of the innings again out of the bullpen.

Mariners' Justin Dunn: To work in opening role again
by RotoWire Staff | RotoWire

Dunn will open Wednesday's game against Pittsburgh, Greg Johns of MLB.com reports.

Dunn got rocked in his debut, allowing two runs over two-thirds of an inning, but he'll get another chance to open ahead of Tommy Milone on Wednesday. He'll aim to show better command in his upcoming outing after issuing five walks Thursday.

Mariners' Justin Dunn: Issues five walks in debut
by RotoWire Staff | RotoWire

Dunn allowed five walks and two runs in two-thirds of an inning against the the Reds on Thursday. He did not factor into the decision.

Whether he was overcome by nervousness or simply a severe lack of control, Dunn struggled mightily to find the strike zone in his first big-league appearance, throwing only 14 of 37 pitches for strikes and walking five of the seven batters he faced. The only two hitters he retired produced sacrifice flies, and he was victimized by three stolen bases behind him. The 23-year-old struggled with his control throughout his minor-league career, compiling an 8.8 percent walk rate in 392.1 innings, though he showed some improvement this season by lowering that number to 7.1 percent in 131.2 frames. Dunn is likely to again serve as an opener Wednesday at Pittsburgh, but he'll need to demonstrate much better control in order to receive consideration for a spot in Seattle's rotation next season.

Mariners' Justin Dunn: Starting Thursday
by RotoWire Staff | RotoWire

Dunn will start Thursday's game against the Reds and is expected to throw a couple innings, Greg Johns of MLB.com reports.

Tommy Milone will relieve him after a couple of innings, and that piggyback setup could continue through the end of the regular season. This role will make it impossible for Dunn to qualify for a win, and he's not an elite pitching prospect by any means, so his fantasy value will be limited.

Mariners' Justin Dunn: Debuting Thursday
by RotoWire Staff | RotoWire

Dunn will work in combination with Tommy Milone every fifth day over the rest of the season, meaning he will pitch in Thursday's game against the Reds, Greg Johns of MLB.com reports.

It's unclear if Dunn will start or relieve in his debut, but it will essentially be a piggybacking situation. For fantasy purposes, it would be better for him to come in after Milone so that he could potentially qualify for a win. Dunn, who is one of Seattle's top pitching prospects, has a deceptive delivery and a few average-to-above-average pitches. He also logged a career-best 7.1 percent walk rate this year at Double-A. Dunn has thrown 131.2 innings and counting in 2019 and should spend the bulk of 2020 in the big-league rotation.

Mariners' Justin Dunn: Receives promotion to majors
by RotoWire Staff | RotoWire

Dunn had his contract selected from Double-A Arkansas on Tuesday, Ryan Divish of The Seattle Times reports.

Dunn posted a 3.55 ERA and 1.20 WHIP with a 158:39 K:BB over 131.2 innings this season as a starter, though he figures to head to the bullpen for the final few weeks of the season in Seattle.

Mariners' Justin Dunn: Likely September promotion
by RotoWire Staff | RotoWire

Dunn is a strong candidate to be called up from Double-A Arkansas sometime in September after rosters expand in September and the Travelers' postseason run concludes, Greg Johns of MLB.com reports.

Arkansas begins a best-of-five playoff series Wednesday and could remain alive all the way through Sept. 15 if it reaches the championship round. Therefore, while an exact arrival date for Dunn would be impossible to pin down at the moment, he is pegged as a highly likely callup, especially since the Mariners would need to add him to the 40-man roster this winter anyhow in order to protect him from the Rule 5 draft. Dunn's first full season at the Double-A level has produced encouraging results, as he owns an 8-5 record, 3.55 ERA, 1.19 WHIP and 153 strikeouts over 126.2 innings.

Mariners' Justin Dunn: Candidate to fill rotation spot
by RotoWire Staff | RotoWire

Dunn is a candidate to be called up and fill in the rotation spot left open by the trade of Mike Leake on Wednesday, Ryan Divish of The Seattle Times reports.

The right-hander is enjoying a solid season at Double-A Arkansas, posting 6-4 record, 3.59 ERA and 1.26 WHIP across 100.1 innings over 19 starts. Unlike his Travelers teammate that's also considered a candidate for promotion, Justus Sheffield, Dunn has never pitched above the Double-A level.

Mariners' Justin Dunn: Invited to Futures Game
by RotoWire Staff | RotoWire

Dunn received an invitation to the 2019 All-Star Futures Game on Friday, Greg Johns of MLB.com reports.

The 23-year-old right-hander has been enjoying a productive season at Double-A Arkansas, and he's coming off back-to-back nine-strikeout efforts. Dunn sports a 5-3 record, 3.45 ERA and 1.22 WHIP across 14 starts, but his swing-and-miss upside is arguably the most impressive aspect of his game. Dunn owns a 90:21 K:BB over 70.1 innings this season, leading to a career-high 11.5 K/9.

Mariners' Justin Dunn: Whiffs six
by RotoWire Staff | RotoWire

Dunn allowed one earned run on two hits and two walks while striking out six across four innings of work Thursday.

Dunn continued to generate whiffs at a strong rate and has 13 strikeouts in nine innings this spring. However, as has been the case throughout his minor-league career, Dunn has struggled with surrendering free passes -- he's now issued five during the exhibition season. Already optioned to minor-league camp, Dunn could get a small sample of big-league work later in the season if he impresses throughout the campaign.

Mariners' Justin Dunn: Sent to minor-league camp
by RotoWire Staff | RotoWire

Dunn was reassigned to minor-league camp Monday, Shannon Drayer of 710 ESPN Seattle reports.

Dunn was invited to big-league camp, although he was never expected to make the Opening Day roster, considering he hasn't played above the Double-A level. He posted a 4.22 ERA and 1.37 WHIP with 105 strikeouts over 89.2 frames last season with Double-A Arkansas. Dunn should spend most of 2019 at Triple-A, but could get a taste of the majors in the second half if he improves his command/control.

Mariners' Justin Dunn: Invited to MLB spring training
by RotoWire Staff | RotoWire

Dunn received an invitation to major-league spring training Thursday, TJ Cotterill of The Tacoma News Tribune reports.

Last season in the Mets' organization, Dunn split time between High-A and Double-A, compiling a 3.59 ERA and a 10.4 K/9 between the two stops. The right-hander will now get a chance to show the Mariners coaching staff what he brings to the table nice and early, though he'll likely see much of his time in 2019 spent at either Double-A or Triple-A, depending on how well he adjusts to upper-level hitters.

Mariners' Justin Dunn: Swapped to Seattle
by RotoWire Staff | RotoWire

Dunn was traded from the Mets to the Mariners on Monday along with Jay Bruce, Anthony Swarzak, Jarred Kelenic and Gerson Bautista in exchange for Edwin Diaz, Robinson Cano and cash considerations, Joel Sherman of the New York Post reports.

Dunn has mid-rotation upside, with a fastball that can touch 97 mph, but it's possible his shaky command eventually prevents him from reaching that ceiling. His slider is a swing-and-miss offering and he made strides with his changeup in 2018. He reached Double-A Binghamton, making 15 starts and posting a 4.22 ERA while striking out 27.7 percent of batters and walking 9.8 percent. He has a shot to reach the majors in 2019 but is most likely tracking towards a 2020 debut.

Mets' Justin Dunn: Impressive Double-A debut Sunday
by RotoWire Staff | RotoWire

Dunn fired seven scoreless innings Sunday for Double-A Binghamton in his Eastern League debut, allowing two hits and four walks while striking out nine in a win over Trenton.

The Mets' No. 5 fantasy prospect didn't seem to miss a beat after slicing through High-A to begin the season. Dunn's control wavered a little -- he threw only 57 of 98 pitches for strikes -- but Trenton's hitters couldn't do anything with the pitches that were over the plate. The 22-year-old right-hander could put himself in line for a September cup of coffee in the majors if he continues to dominate in the high minors over the rest of 2018.

Mets' Justin Dunn: Promoted to Double-A
by RotoWire Staff | RotoWire

Dunn was promoted to Double-A Binghamton on Friday, Tim Healey of Newsday reports.

The 19th overall pick in the 2016 draft, Dunn was pretty mediocre in his first full season in 2017, but has reestablished his prospect stock this season. He logged a 2.36 ERA, 1.27 WHIP and 51:15 K:BB in 45.2 innings (nine starts) at High-A, and will look to further increase his stock by producing at a more age-appropriate level.

Mets' Justin Dunn: Fans 10 in dominant effort at High-A
by RotoWire Staff | RotoWire

Dunn didn't factor into the decision for High-A St. Lucie in Monday's extra-inning win over Tampa, scattering two hits and a walk over seven scoreless innings while striking out 10.

The Mets' No. 5 fantasy prospect set season highs in both innings and strikeouts in this one, lowering his ERA to 2.36 in the process. Dunn is likely due for a promotion before the summer is over, as the 22-year-old now sports a 51:15 K:BB through 45.2 innings. While the organization will keep a close eye on his workload after he threw only 95.1 innings last year, if he continues his current form at Double-A, he could potentially put himself on the fringes of the big-league rotation picture for 2019.

Mets' Justin Dunn: Strong start to season at High-A
by RotoWire Staff | RotoWire

Dunn struck out seven over five scoreless innings for High-A St. Lucie in Wednesday's win over Tampa, allowing two hits and three walks.

After struggling in his first taste of High-A last summer, Dunn has flipped the script to begin 2018, posting a 0.00 ERA and 14:3 K:BB in his first 10 innings. Given that he's already 22 years old, dominating at this level is more expected than surprising, so the Mets will likely move him up to Double-A in short order if he continues his current form. The 19th overall pick in the 2016 draft will need to show that his changeup can be a viable third pitch to project as a starter down the road, but if the organization does convert Dunn to relief, his mid-90s fastball and tight slider could land him in the big-league bullpen for the stretch run.

Mets' Justin Dunn: Struggling at High-A
by RotoWire Staff | RotoWire

Dunn, 21, has a 4.74 ERA, 1.57 WHIP and 49:34 K:BB in 68.1 innings for High-A St. Lucie.

The Mets jumped last year's 19th overall pick from short-season ball to High-A, and thus far the results have not been great. His lack of control is particularly concerning for a college arm in the lower levels of the minors. There are plenty of electric arms that are producing at Low-A and High-A, so Dunn's lack of performance is hurting his stock.
