Mariners Activate Justin Dunn, Kendall Graveman; Option Keynan Middleton, DFA Yacksel Rios

The Mariners had a busy morning in Cleveland, as they made a series of moves to realign their pitching staff. The players returning are certainly a big deal: Graveman is the Mariners’ unquestioned relief ace, and Dunn—the subject of fierce debate in our comments regarding his ethereal ability to escape troubles, evidenced by his 3.18/4.44/5.53 ERA/FIP/xFIP split—stabilizes a rotation that yet again had been reduced from a full 6-man slate by injuries. Dunn will start tonight in Cleveland, a nice way to be eased back into things against one of the league’s lesser offenses.

Mariners' Keynan Middleton: Activated Friday

Middleton (biceps) was activated from the 10-day injured list Friday. He missed almost three weeks with a strained biceps. Relievers Anthony Misiewicz and Drew Steckenrider each landed on the injured list in the same flurry of moves. Middleton should pitch in mid-to-high leverage spots.

Mariners' Keynan Middleton: Throwing live BP on Monday

Middleton (biceps) will throw live batting practice Monday, Shannon Drayer of 710 ESPN Seattle reports. The 27-year-old landed on the shelf with a strained right biceps May 5, and he's in the final stages of his rehab work. Middleton could be activated this week if all goes well during Monday's session.

Mariners' Keynan Middleton: Working on scoreless streak

Middleton has fired 5.2 scoreless innings during which he's allowed only one hit while posting a 5:2 K:BB across his last six appearances. The big right-hander also secured his first hold of the season in his most recent appearance, which consisted of a scoreless two-thirds of an inning versus the Astros on Wednesday. Middleton brings some solid high-leverage experience and a mid-90s fastball to the table, and he's primarily been deployed as a seventh- and eighth-inning asset thus far by manager Scott Servais.

Keynan Middleton has come full circle

Keynan Middleton was supposed to be the Angels’ closer of the future. So you can imagine that it was pretty disappointing when he went down with Tommy John surgery, and even more disappointing when he came back as a shell of the pitcher he was before. The Angels, apparently, didn’t consider it a priority to bring him back to their middling bullpen, which isn’t exactly something that speaks well to Middleton. Perhaps, then, the Mariners may have seen something that they could unlock.

Mariners' Keynan Middleton: Records second save of season

Middleton picked up the save in Game 2 of Thursday's doubleheader against the Orioles. He gave up a hit with no walks and no strikeouts in his lone mining of work. Middleton pitched the seventh inning in Game 2 and while he only tossed 10 of his 17 pitches for strikes, that was enough to get the job done. The 27-year-old right-hander, who allowed a single to Rio Ruiz but recorded the three outs with two groundouts and a flyout to right, has not allowed runs in three of his four appearances this season while going 2-for-2 in save opportunities, so he might be in line for late-inning duties going forward even though Rafael Montero and Kendall Graveman are ahead of him in the pecking order.

Mariners' Keynan Middleton: High-leverage role planned

Middleton is still ticketed for high-leverage opportunities during the 2021 season despite struggling thus far in Cactus League play, Daniel Kramer of reports. The big right-hander has allowed a total of seven earned runs on seven hits, including four home runs, and one walk over three innings across his first three spring appearances, so the landing in Seattle has been rough to say the least. However, Kramer notes that Middleton, along with presumptive primary closer Rafael Montero and veteran Kendall Graveman, are the three players the Mariners have earmarked for the "highest-leverage innings." Middleton's difficult exhibition slate thus far is somewhat reminiscent of his 2020 with the Angels (5.25 ERA, 1.50 WHIP), but prior to last season, the 27-year-old generated a 6-1 mark, 3.23 ERA, nine saves (in 12 chances) and 12 holds across 91 appearances during the 2017-19 seasons.

Earlier this offseason, Jerry Dipoto said something about focusing on bullpen additions as a way to improve the Mariners’ roster for 2021. I’m not going to hunt down the exact quote, but you read this site, you know what I’m talking about. As visions of faceless veterans wriggling their way...

Mariners Moose Tracks, 1/23/21: Keynan Middleton, Jameson Taillon trade rumors, the Red Sox get active, RIP Larry King

Happy Sunday! The Mariners are taking the weekend off from their virtual Fan Fest type activities (still refusing to call it “Baseball Bash”), but there’s still plenty of rumor-mongering around the league as the Hot Stove gradually heats back up. And if you had a particularly busy week, make sure to poke around on the homepage, as there was quite a bit of content on the site this past week. (And next week will likely be the same, with the [grits teeth] Baseball Bash continuing, and Spring Training drawing one precious week closer.)

Seattle Mariners continue bullpen makeover, sign Keynan Middleton

SEATTLE -- The Seattle Mariners continued their bullpen overhaul Wednesday by signing right-handed reliever Keynan Middleton.

Middleton has appeared in just 24 major league games over the past two seasons.
