Mariners' Justin Dunn: Gets win in nightcap
by RotoWire Staff | RotoWire

Dunn (4-1) allowed three runs on six hits and two walks while striking out two over five innings in a win in Game 2 of Saturday's doubleheader versus the Athletics.

Dunn allowed a pair of solo shots to Robbie Grossman and an RBI single to Jake Lamb, but the righty was well-supported by the Seattle offense in the nightcap. Across 10 starts in 2020, Dunn has a 4.34 ERA, 1.36 WHIP and 38 strikeouts in 45.2 innings. He also permitted 10 homers and walked 32 batters.

Mariners' Justin Dunn: Decent in no-decision
by RotoWire Staff | RotoWire

Dunn allowed three runs on two hits and four walks with six strikeouts in 5.2 innings in a no-decision versus the Padres on Sunday.

Dunn was effective Sunday, but manager Scott Servais may have left him in the game too long. Dunn walked Eric Hosmer and gave up a ground rule double to Mitch Moreland before Wil Myers lifted a three-run homer to end the right-hander's outing. The 24-year-old Dunn has a 4.20 ERA, 1.33 WHIP and 36 strikeouts across 40.2 innings this season. He will likely get one more start in 2020, which lines up with Saturday's doubleheader versus the Athletics.

Mariners' Justin Dunn: Wild in short outing
by RotoWire Staff | RotoWire

Dunn allowed one run on one hit and five walks across two innings in Sunday's 7-3 win over the Diamondbacks. He fanned five and did not factor in the decision.

Though he tallied five strikeouts, Dunn was pulled after throwing 66 pitches over just two innings. Despite struggling badly with his command and issuing five free passes, the right-hander managed to limit Arizona to just one run. The 24-year old will look to display better control and work deeper into the game when he takes the ball next Sunday against the Padres.

Mariners' Justin Dunn: Fans four in win
by RotoWire Staff | RotoWire

Dunn (3-1) allowed two runs on four hits and four walks over six innings Sunday, striking out four and earning the win over the Rangers.

Aside from a pair of solo homers by Joey Gallo and Leody Taveras, Dunn kept the Texas offense fairly quiet Sunday. Despite walking four batters, the 24-year-old righty threw a respectable 63 strikes on 93 pitches in the outing. He'll carry a 4.09 ERA into next Sunday's road matchup with Arizona.

Mariners' Justin Dunn: Spins six scoreless innings
by RotoWire Staff | RotoWire

Dunn tossed six scoreless innings, allowing a hit and four walks while striking out six in a no-decision versus the Angels on Sunday.

Dunn and Angels starter Griffin Canning engaged in a pitchers' duel throughout the contest. Dunn hasn't allowed a run in his last two outings, compiling 12 scoreless innings in that span. The 24-year-old has a 4.33 ERA, 1.26 WHIP and 21 strikeouts through 27 innings this season. Dunn's next started is expected to come Saturday versus the Rangers.

Mariners' Justin Dunn: Shines in win
by RotoWire Staff | RotoWire

Dunn (2-1) pitched six scoreless innings in a win over the Rangers on Sunday. He allowed one hit and one walk and struck out six.

Dunn had a fantastic outing, starting with four no-hit innings. Even when he did allow baserunners, he was able to escape the danger unscathed. Sunday was easily Dunn's best start of the year, and he now has a 5.57 ERA, 1.38 WHIP and 15 strikeouts in 21 innings this season. He'll look to put in another solid effort versus the Angels next Sunday.

Mariners' Justin Dunn: Cleared to start Sunday
by RotoWire Staff | RotoWire

Mariners manager Scott Servais said Dunn (ribs) has been cleared to make his next scheduled start Sunday against the Rangers, Greg Johns of reports.

Dunn took a liner to the midsection during his last start Monday against the Dodgers, exiting after he allowed six runs over two innings. He was fortunate to escape the outing with little more than sore ribs, an injury that didn't prevent him from completing his between-starts bullpen session without incident. The Mariners likely won't have Dunn work deep into his upcoming start, but he hasn't been able to stick around long in his appearances even when healthy this season. He's covered more than four innings only once in four starts, and he'll take a 7.80 ERA and 1.80 WHIP into Sunday's turn.

Mariners' Justin Dunn: Dealing with sore ribs
by RotoWire Staff | RotoWire

Dunn exited Monday's start against the Dodgers after two innings with sore ribs stemming from a comeback liner off the bat of Corey Seager, but the rookie is expected to make his next start Bill Ladson of reports.

The 24-year-old had a rough night overall, allowing six earned runs on five hits and a walk over two innings. The rib injury, which occurred in the first inning on a 99.5 mph comebacker, wasn't enough to knock Dunn out of the game, but it did affect him the rest of the way. Dunn mentioned after the game that it specifically prevented him from throwing his slider due to the discomfort the mechanics of deploying that pitch caused. The right-hander will be considered day-to-day ahead of his next scheduled start, which currently lines up for Sunday against the Rangers.

Mariners' Justin Dunn: Lasts only two innings
by RotoWire Staff | RotoWire

Dunn gave up six runs on five hits and a walk over two innings in a no-decision versus the Dodgers on Monday. He struck out one.

Dunn was ineffective in the short outing, which saw his ERA rocket up to 7.80 across 17 innings this season. The 24-year-old righty has struggled more often than not in 2020, which is his first season as a full-time big-league pitcher. Dunn is expected to face the Rangers on Sunday in his next start.

Mariners' Justin Dunn: Earns first win
by RotoWire Staff | RotoWire

Dunn (1-1) earned the win Monday versus the Rangers, allowing two runs on seven hits and three walks over six innings. He struck out two.

Dunn was a bit generous with baserunners, but the Rangers didn't capitalize on most of their opportunities. The 24-year-old has pitched to a 4.85 ERA, 1.62 WHIP and eight strikeouts in 13 innings across three starts this year. With the Mariners running a six-man rotation at the moment, Dunn isn't expected to make his next start until Aug. 17 versus the Dodgers in Los Angeles.

Mariners' Justin Dunn: Tagged with loss
by RotoWire Staff | RotoWire

Dunn (0-1) was tagged with the loss Tuesday against the Angels after allowing three runs on three hits and four walks across four innings. He struck out four.

Dunn gave up two homers in the first inning -- a solo shot to Mike Trout and a two-run blast to Albert Pujols -- and that would set the tone for the rest of his outing. He has now given up five earned runs on four hits in seven innings across two starts this season, although three of those hits have left the ballpark. His next start is scheduled for Aug. 10 at Texas.

Mariners' Justin Dunn: Gives up three runs
by RotoWire Staff | RotoWire

Dunn didn't factor into the decision in Wednesday's 10-7 win over the Angels. He gave up three runs (two earned) on one hit and three walks while fanning two across three innings.

Dunn surrendered a three-run shot to Shohei Ohtani in the bottom of the fourth on an 0-2 count, but that would be all the damage he'd allow in what was a short three-inning outing for the 24-year-old right-hander. He should remain as the team's sixth starter moving forward, with his next chance to pitch looking like Aug. 4 against the Angels once again.

Mariners' Justin Dunn: Opens year as sixth starter
by RotoWire Staff | RotoWire

Dunn is scheduled to make his first start of the season Wednesday against the Angels, Greg Johns of reports.

As anticipated, Dunn will begin the season as the Mariners' sixth starter after manager Scott Servais decided to expand the rotation due to the compressed schedule in the 60-game campaign. The 24-year-old will likely have his workload managed more carefully than the Mariners' other rotation members, but he should be a decent source of strikeouts on a per-inning basis after whiffing 28.6 percent of his opposing hitters he faced at the Double-A level in 2019.

Mariners' Justin Dunn: Encouraging results in start
by RotoWire Staff | RotoWire

Dunn, who recorded five strikeouts over three innings in Thursday's intrasquad game, focused on his breaking pitches with considerable success, Shannon Drayer of 710 ESPN Seattle reports. "It was shaky last week," Dunn said of his slider and curveball. "I wasn't too happy about that. It's something I take pride in being able to spin the ball when I want to. I was able to lock in the routine with Woody (pitching coach Pete Woodworth) and was able to work on both pitches and felt like I executed both pretty well today."

Both Dunn's curveball and slider paid dividends Thursday, as the right-hander threw the former for multiple first-pitch strikes and was able to retire a few teammates with the latter. Dunn's most impressive frame was the second, when he mowed down a side consisting of J.P. Crawford, Tim Lopes and Tom Murphy on swinging strikeouts. Dunn will have one more start before the regular season, which he's likely to enter as the No. 6 starter.

Mariners' Justin Dunn: Throws live BP in camp
by RotoWire Staff | RotoWire

Dunn threw a 20-pitch live batting practice session against Dee Gordon and other teammates during Saturday's summer camp session and was particularly impressive with his breaking pitch, Shannon Drayer of 710 ESPN Seattle reports. "It's a big year for Justin," said manager Scott Servais. "I like where he is at; he knows what is ahead of him. I think the fact that we are going to go with a six-man rotation gives him an opportunity to make 10 starts."

The young right-hander, who's thought to have a chance to open the 2020 season at the back end of the starting rotation, has jumped right into action at the Mariners' summer camp at T-Mobile Park. While Dunn's options for throwing and working out were limited early during the shutdown, he and several teammates eventually gained regular access to an indoor facility in the Arizona area. Dunn subsequently was one of the first arrivals when the Mariners reopened their spring training facility in Peoria, and the regular routine he was able to maintain is now paying off. "I'm definitely ready to go," Dunn said. "I understand there is still some room to go with building up and really locking in the pitches and fine tuning and getting it into game shape, but I definitely feel strong. I feel I haven't really regressed since spring training, which I am really happy about."

Mariners' Justin Dunn: Rotation chances boosted
by RotoWire Staff | RotoWire

Dunn is much more likely to open the 2020 regular season in the starting rotation now that expanded rosters are official, Greg Johns of reports.

General manager Jerry Dipoto confirmed in a Zoom call with reporters Wednesday that the Mariners were slated to start the campaign with a six-man starting rotation. Johns explains it's highly likely that extra spot goes to Dunn, who appeared to just be on the outside looking in with respect to a starter's role when spring training was suspended. The 24-year-old right-hander put together a solid Cactus League stint (2.70 ERA, 1.05 WHIP across 6.2 innings) and has been throwing regularly while play has been paused, and Dipoto estimated Wednesday that at present, Dunn and the rest of the team's hurlers are approximately where they'd be after an initial two-inning outing in spring training with respect to their arms.

Mariners' Justin Dunn: Access to facility forthcoming
by RotoWire Staff | RotoWire

Dunn, who's remained in Arizona while play has been paused, should be one of the players that begins working out at the team's spring training facility next week, Greg Johns of reports.

The promising pitcher has had the opportunity to work out regularly with several of his teammates during the shutdown at a facility near the team's complex in Peoria, Shannon Drayer of 710 ESPN Seattle reports. However, with the Mariners being granted permission to reopen their spring facility next week and host small groups of players, Dunn figures to be front and center as far as returning to a regular training routine. With expanded rosters fully expected to be part of any 2020 season that does unfold, the 24-year-old seems very likely to stick with the big-league club.

Mariners' Justin Dunn: Makes strong impression in spring
by RotoWire Staff | RotoWire

Dunn, who posted a 2.70 ERA and 1.05 WHIP across 6.2 innings before spring training was suspended, made a strong case to spend minimal time in the minors this season, if any, Brent Stecker of 710 ESPN Seattle reports.

The promising right-hander coincidentally posted the same ERA over the same amount of innings during his September big-league cup of coffee last season. However, in contrast to the nine walks Dunn issued during that span, he handed out just three free passes while recording an impressive 10 strikeouts over his three Cactus League appearances. Stecker notes Dunn entered camp with the inside track to the fifth spot in the starting rotation, but the subsequent signing of veteran Taijuan Walker seemingly dampened the former's chances. However, with the possibility rosters are expanded beyond 26 players to open the delayed regular season, Dunn could still potentially stick on the Opening Day roster. Moreover, even if he does open the season at Triple-A Tacoma, Stecker notes the 24-year-old should be first pitcher called up should injuries strike the rotation.

Mariners' Justin Dunn: Goes on strikeout spree
by RotoWire Staff | RotoWire

Dunn fired three scoreless innings in a Cactus League loss to the Brewers on Monday, allowing one hit and no walks while recording five strikeouts.

The young right-hander faced 11 batters overall, so he mowed down nearly half the hitters that came to the plate against him. Daniel Kramer of reports Dunn's strikeout victims included Christian Yelich, Avisail Garcia, Jedd Gyorko and Justin Smoak, making the feat all the more noteworthy. Dunn, who could see multi-inning relief work if he's unable to secure a rotation spot to open the season, received high praise from manager Scott Servais, who called the prospect's appearance "probably the best outing he's had so far this spring."

Mariners' Justin Dunn: Two innings in spring debut
by RotoWire Staff | RotoWire

Dunn started Wednesday's Cactus League win over the Reds, allowing an earned run on two hits and a walk over two innings. He struck out two.

The right-hander, who logged the first four starts of his major-league career at the tail end of 2019, was sharp in his first taste of game action this spring. Per Greg Johns of, Dunn consistently hit between 94 mph and 96 mph with his fastball, which helped him to his pair of whiffs, including one of Joey Votto. Dunn made an impression on both the Reds -- which got to him for two earned runs on five walks over two-thirds of an inning in his first big-league turn Sept. 12 -- and manager Scott Servais, who saw the mechanical and mental adjustments Dunn made over the offseason pay immediate dividends. "I was really impressed with Justin today," manager Scott Servais said. "Just his whole demeanor, attacking with his fastball early in the ballgame was great to see. He feels good about where he's at right now."
