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

EDGE Analysis

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.

The Mariners designated Muckenhirn for assignment Wednesday.

EDGE Analysis

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.

The Mariners acquired Muckenhirn from the Mets on Monday in exchange for right-handers Chris Flexen and Trevor Gott, Ken Rosenthal of The Athletic reports. Seattle optioned him to Triple-A Tacoma.

EDGE Analysis

The transaction frees up a spot on the 40-man roster for the Mariners while also sparing Seattle from covering 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 could be one of the top options for a promotion when the Mariners require a lefty arm in the bullpen.

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

EDGE Analysis

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.

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

EDGE Analysis

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.

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

EDGE Analysis

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.

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

EDGE Analysis

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.
