Mariners Designate Tommy Milone, Select Jose Caballero

The Mariners announced that left-hander Tommy Milone has been designated for assignment.  In a corresponding move, Seattle selected the contract of infielder Jose Caballero from Triple-A.

After originally signing a minor league deal with the Mariners prior to the 2022 season, Milone rejoined the club on a new minors deal this past winter, and was then selected to the MLB roster just yesterday.  Milone got the spot start and was solid (one ER on three hits and two walks over 4 2/3 innings) in Seattle’s 5-3 win over the Rockies, and that game officially put Milone on the books for 13 Major League seasons.

Depending on what happens on DFA waivers, however, this cup of coffee could potentially be the end of Milone’s tenure with the Mariners, if another team in need of starting depth made a claim or worked out a trade with the M’s.  It perhaps seems more likely that Milone will clear waivers and then remain in the organization as a swingman or depth option, ready to be called back up to Seattle if another need arises in the rotation or bullpen.

Milone’s long career has seen him suit up with nine different teams at the big league level, and he has posted a 4.59 ERA over 949 career innings.  Between injuries and time in the minors, Milone has seen limited action over the last three seasons, with only 35 1/3 total innings pitched in the majors since the start of the 2021 season.

As Milone’s career takes its latest turn, Caballero may be on the verge of his MLB debut.  A seventh-round pick for the Diamondbacks in the 2017 draft, the M’s acquired Caballero in exchange for Mike Leake at the 2019 trade deadline.  Caballero has some solid numbers over his minor league career but he had trouble staying healthy, with only 53 total games played over the 2021-22 seasons.  He is off to a very nice start in his first taste of Triple-A ball this season, as Caballero has hit .333/.550/.593 with two homers over his first 40 plate appearances of the 2023 campaign.

It might be a short-lived stint in the bigs for Caballero, as Ryan Divish of the Seattle Times notes that the Mariners made the call-up since Sam Haggerty was shaken up after a dive in yesterday’s game.  If Haggerty ends up being okay, Caballero might end up back at Triple-A when Marco Gonzales returns from the paternity list later in the week.  In the meantime, Caballero’s ability to play shortstop, second base, and third base will help fill Haggerty’s utility role.
