Mariners Sign Yunior Marte To Minor League Deal

The Mariners have signed right-hander Yunior Marte to a minor league deal, according to a report from Francys Romero. Romero adds that the deal comes with an invite to MLB Spring Training.

Marte, 30 in February, signed with the Royals out of the Dominican Republic and made his pro debut back in 2013. He worked his way up the minor league ladder with Kansas City until he reached minor league free agency following the cancelled MiLB season in 2020, and eventually signed a minors pact with the Giants prior to the 2021 season. The right-hander spent two years in the Giants organization and pitched well at Triple-A despite the inflated offensive environment of the Pacific Coast League, prompting Marte’s promotion to San Francisco in April of 2022.

In the majors, Marte collected 48 innings with the Giants across 39 appearances. He posted a lackluster 5.44 ERA during that time, though his peripheral numbers (including a 4.38 FIP and 3.80 xERA) were solid enough. He struck out just 20.6% of opponents while walking 10.3%, but helped make up for that by generating poor contact, as evidenced by an impressive 48.6% groundball rate and a microscopic 3.5% barrel rate. That performance was solid enough to earn Marte a spot on the club’s 40-man roster throughout the offseason, but he nonetheless found himself traded to Philadelphia that January in exchange for southpaw Erik Miller.

Philly would serve as Marte’s home in each of the next two seasons, though his struggle to find results at the big league level continued. While Marte impressed with a 1.80 ERA in 20 Triple-A innings in 2023, his time in the majors told a different story as he surrendered a 5.03 ERA with a 4.68 FIP across 39 1/3 frames. While Marte’s strikeout, walk, and grounder rates all improved, opposing hitters began to find more success barrelling him up and that led to a spike in homers, which perhaps isn’t especially surprising given he moved from Oracle Park in San Francisco to the Phillies’ homer-happy home of Citizen Bank Park.

2024 turned out even worse for Marte, as the 29-year-old pitched to a 6.92 ERA with a 5.63 FIP while posting the worst strikeout rate, walk rate, groundball rate, and home run rate of his major league career. The disastrous results even carried over to Triple-A this season, as he surrendered a 6.88 ERA in 17 innings at the level. That led the Phillies to outright Marte off their roster earlier this month, and he subsequently elected free agency. The right-hander has now found a new home in Seattle, and he’ll have the opportunity to try and find his footing in an organization that boasts one of the best pitching staffs in the majors. That strong pitching staff could mean that Marte faces an uphill battle in trying to secure an Opening Day roster spot this spring, and barring him securing that roster spot he’ll likely open the season as non-roster depth for the Mariners in case of an injury.
