Mariners Select Tommy Milone, Designate J.B. Bukauskas

The Mariners announced that they have selected left-hander Tommy Milone. He will take the active roster spot of fellow lefty Marco Gonzales, who has been placed on the paternity list. To open a spot on the 40-man for Milone, right-hander J.B. Bukauskas was designated for assignment.

Milone, 36, is a veteran journeyman who was suited up for the Nationals, Athletics, Twins, Mets, Mariners, Orioles, Braves and Blue Jays in his career. Though he was capable of holding down a full-time rotation spot earlier in his career, he’s mostly been called upon for emergency spot start duties or long relief in recent years. Since the end of the 2019 season, he’s made 22 appearances, including 10 starts, posting a 6.33 ERA over 69 2/3 innings. He doesn’t rack up strikeouts but has strong control, with a 5.6% walk rate in his career.

Last year, Milone made seven appearances for the M’s, posting a 5.40 ERA in 16 2/3 innings. He also tossed 40 1/3 innings in Triple-A with a 2.68 ERA. He signed a minor league deal with the club over the winter and has already made one Triple-A start here in 2023, tossing five scoreless innings back on April 4.

The Mariners went into the season with six solid starters, pushing Chris Flexen to a long relief role in the bullpen. However, Robbie Ray landed on the injured list just a few days into the season, with a rough expectation of an absence of four to six weeks. That required putting Flexen back into the rotation and now Milone will step up to start tonight’s game while Gonzales steps away for the birth of his child. Stints on the paternity list are allowed for between one and three days, so it seems likely this will be just a single spot start for Milone.

More to come.
