Zach Muckenhirn - MLB News, Rumors, & Updates | FOX Sports

Outrighted to Triple-A Muckenhirn cleared waivers Friday and was sent outright to Triple-A Tacoma.

Impact The Mariners DFA'd Muckenhirn on Wednesday, and he will officially remain in the organization after going unclaimed. The 28-year-old reliever hasn't pitched for Seattle in the majors since being traded from the Mets in July, but he's put up a 9.35 ERA and 1.95 WHIP through 8.2 frames with Tacoma.

Loses 40-man spot The Mariners designated Muckenhirn for assignment Wednesday.

Impact The southpaw will move off the Mariners' 40-man roster with Seattle needing to clear a spot for right-hander Emerson Hancock, whose contract was selected from Double-A Arkansas ahead of his first MLB start Wednesday versus the Padres. Since being acquired in a trade with the Mets on July 3, Muckenhirn has pitched exclusively at Triple-A Tacoma, where he turned in a 9.35 ERA and 1.95 WHIP over 8.2 innings.

Dealt to Seattle The Mariners acquired Muckenhirn from the Mets on Monday in exchange for right-handers Chris Flexen and Trevor Gott, Joel Sherman of the New York Post reports.

Impact The transaction frees up a spot on the 40-man roster for the Mariners while also sparing Seattle from paying the approximately $4.6 million remaining on the contracts of Flexen and Gott for the 2023 season. A 28-year-old southpaw, Muckenhirn reached the majors for the first time earlier this season and made three appearances for the Mets, but the bulk of his innings have come at Triple-A Syracuse, with whom he's produced a tidy 0.88 ERA and 1.13 WHIP over 30.2 innings. Muckenhirn has three minor-league options remaining, but the Mariners may choose to keep him with the big club to fill the vacancy left in the bullpen with the departure of Gott.

Designated for assignment Muckenhirn was designated for assignment Monday, Will Sammon of The Athletic reports.

Impact Muckenhirn has allowed four runs in six relief innings with the Mets this season. He's spent most of the year at Triple-A Syracuse, where he's posted a 0.88 ERA but with just 19 strikeouts in 30.2 frames.

Sent back to Syracuse Muckenhirn was optioned to Triple-A Syracuse on Saturday, Bob Nightengale of USA Today reports.

Impact Muckenhirn was called up Friday but was knocked around by the Pirates that same night, giving up three runs on six hits across 2.1 innings of relief. Josh Walker was called up to take his place in the bullpen.

Officially promoted The Mets recalled Muckenhirn from Triple-A Syracuse on Friday, Anthony DiComo of MLB.com reports.

Impact Muckenhirn has been very impressive this season in Syracuse, logging a 1.11 ERA and 1.04 WHIP through 24.1 innings. A low strikeout rate makes him unlikely to see many high-leverage situations, but he has the capability to pitch multiple innings out of the bullpen. Stephen Nogosek was designated for assignment Friday to make room for Muckenhirn on the active roster.

Could be headed to majors Muckenhirn could be in line for a promotion to the majors, Mike Puma of the New York Post reports.

Impact The Mets are in need of a fresh bullpen arm and Puma hears that Muckenhirn is the likely choice to be summoned. The left-handed reliever has yielded one run over 3.2 innings at the big-league level this season.

Goes back to minors The Mets optioned Muckenhirn to Triple-A Syracuse on Monday.

Impact Muckenhirn was up with the Mets for just one day, as he served as the team's 27th man for Sunday's doubleheader with the Nationals. The left-hander appeared out of the bullpen in the Mets' 8-2 win in Game 2, working two innings while giving up one run on four hits and one walk.

Gets call for doubleheader The Mets recalled Muckenhirn from Triple-A Syracuse ahead of the second game of Sunday's doubleheader with the Nationals, Abbey Mastracco of the New York Daily News reports.

Impact He'll be in line for his second stint with the big club this season, after he previously tossed 1.2 scoreless innings in his lone appearance out of the bullpen earlier in May. Muckenhirn should be capable of giving the Mets multiple innings out of the bullpen behind starter Max Scherzer if necessary, but expect the rookie to return to Syracuse immediately after Sunday's game.

Optioned to Triple-A Muckenhirn was optioned to Triple-A Syracuse by the Mets on Thursday, Anthony DiComo of MLB.com reports.

Impact Muckenhirn tossed 1.2 scoreless innings in his major-league debut Wednesday and his reward is a trip back to the minors so the Mets can have a fresh arm. The left-hander should get another opportunity down the line.

Nabs first MLB call-up The Mets selected Muckenhirn's contract from Triple-A Syracuse prior to the second game of Monday's doubleheader with Atlanta.

Impact The Mets will have Muckenhirn and Jose Butto -- who was designated as the 27th man for the twin bill -- available to provide length behind starter Tylor Megill for the second game after New York treated the opening game as a bullpen day, with five relievers covering nine innings in the 9-8 loss. Muckenhirn is in the majors for the first time in his career after he churned out a 0.77 ERA and 1.25 WHIP over 11.2 innings at Syracuse, though those ratios were supported by a poor 4:4 K:BB.
