Mariners outright lefty pitcher Joe Jacques to Triple-A

The Seattle Mariners outrighted left-hander Joe Jacques to Triple-A yesterday, according to the transactions log on his MLB.com profile page. Jacques was designated for assignment by the club earlier this week when southpaw Jose Castillo was claimed off waivers from the Mets.

Jacques, 30, was a 33rd-round pick by the Pirates all the way back in 2018. He climbed the minor league ladder with Pittsburgh but ultimately departed the organization following the 2022 season without making it to the big leagues. He signed on with the Red Sox and made his major league debut with the club in 2023, but posted a lackluster 5.06 ERA in 26 2/3 innings of work. He remained on Boston’s 40-man roster throughout the 2023-24 offseason, but ultimately made just one appearance at the big league level in 2024 before he was designated for assignment and plucked off waivers by the Diamondbacks. He made only one appearance with Arizona as well before he was once again DFA’d.

Bouncing around

He elected minor league free agency during the offseason and landed with the Dodgers on a non-roster deal last November. His 6.04 ERA in 22 1/3 innings of work with the club’s Triple-A affiliate in Oklahoma City left much to be desired and prevented him from making it to the big leagues in L.A., but the Mariners were sufficiently intrigued by his solid underlying metrics to roll the dice on him back in June and acquire him in a minor trade with the Dodgers. His performance at the Triple-A level did not improve with the move to Tacoma, as he has struggled to a 6.93 ERA in 24 appearances with the Rainiers this year. Seattle added him to their 40-man roster a month later, but he was never recalled from Tacoma to make his Mariners debut before being DFA’d earlier this week.

Should Jacques accept his outright assignment, he’ll remain in Tacoma for the remainder of the year as a non-roster depth piece for Seattle before having another chance to elect minor league free agency after the season concludes, if he isn’t added back to Seattle’s 40-man roster before then. If he decides to elect minor league free agency, perhaps he can catch on somewhere as a depth option for the stretch run, though he might also look to get a head start on the offseason market and begin searching for a place to play in 2026.

As for the Mariners, they now have Castillo to join Gabe Speier and Caleb Ferguson as left-handed options in their bullpen at the big league level. Tayler Saucedo is in Triple-A and already on the 40-man roster, likely making him the club’s top depth option for filling that role, but if Jacques remains in the organization he could compete with Austin Kitchen to be the next man up after that quartet.
