The Mariners selected Rucker's contract from Triple-A Tacoma on Thursday.
Rucker will return to the majors for the first time since 2023 after posting a 1.59 ERA and 1.62 WHIP through 22.2 innings at Tacoma. He'll take the place of Domingo Gonzalez, who was designated for assignment in a corresponding move.

The Mariners reassigned Rucker to minor-league camp Sunday.
After sitting out the entire 2025 season, Rucker signed a minor-league deal with the Mariners in January and had been attending camp as a non-roster invitee. He's expected to open the upcoming campaign at Triple-A Tacoma and will serve as bullpen depth. The 31-year-old previously saw big-league action with the Cubs in 2021-23, logging a 4.96 ERA and 1.39 WHIP over 123.1 innings across 96 regular-season relief appearances.

Rucker elected free agency Monday, Bobby Blanco of MASNSports.com reports.
The Nationals booted Rucker from their 40-man roster and he has decided to try out free agency rather than accepting an outright assignment. The 30-year-old spent the entirety of the 2024 campaign in the minors, holding a 6.16 ERA and 39:11 K:BB over 30.2 innings.

The Nationals claimed Rucker off waivers Friday and optioned him to Triple-A Rochester.
The right-hander was designated for assignment by the Phillies on Wednesday, and he'll stick in the NL East after being claimed off waivers. Rucker hasn't pitched in the majors this season and has struggled at the Triple-A level with a 7.36 ERA across 22 innings, though he was a solid bullpen piece for the Cubs in 2022 with a 3.95 ERA in 41 appearances.

The Phillies designated Rucker for assignment Wednesday, Todd Zolecki of MLB.com reports.
Rucker has missed much of 2024 due to injury, posting a 6.58 ERA but also a 36:11 K:BB over 26 innings in the minors. The 30-year-old will cede his 40-man roster spot to Nick Nelson, who was called up from Triple-A Lehigh Valley on Wednesday.

Sent to Triple-A
He'll give up his spot on the 26-man active roster and in the Philadelphia bullpen to right-hander Carlos Estevez, whom the Phillies acquired from the Angels over the weekend. Rucker has spent most of the season recovering from a right hand arterial vasospasm, but the Phillies brought him back from the 60-day injured list Friday. The righty didn't end up making any appearances out of the bullpen over the weekend in the Phillies' series with the Guardians, however.
