Mariners Designate Phillips Valdez For Assignment

By Anthony Franco and Nick Deeds | September 30, 2022 at 3:57pm CDT

The Mariners announced they’ve designated right-hander Phillips Valdez for assignment. The move clears a spot on the 40-man roster for backstop Brian O’Keefe, whose selection to the majors was reported this morning.

Valdez was claimed off waivers by Seattle in late July after the Red Sox designated him for assignment. The righty had been with the Red Sox since the 2020 season, when they claimed him off waivers themselves from the Rangers. For his major league career, Valdez has posted a 4.56 ERA and matching 4.59 FIP in 102 2/3 innings.

Valdez never made it into a game for Seattle this season, though he posted a 4.41 ERA in 16 1/3 innings with Boston this season. Otherwise, he has pitched at the Triple-A level this season, posting a 3.60 ERA across 39 innings split between the Worcester Red Sox and the Tacoma Rainiers. While his Triple-A numbers have been respectable this season, Valdez has seemingly struggled with his command during his time in the majors this season, walking seven while hitting another six batters.

Seattle will have 7 days to either release Valdez or send him through outright waivers. Should he be outrighted, Valdez will qualify for minor league free agency this offseason unless the Mariners add him back onto the 40-man roster. With Valdez off the 40-man, the Mariners still have Brennan Bernardino, Juan Then, and Justus Sheffield on the roster as depth options in the minors.

Mariners To Select Brian O’Keefe

By Jacob Smith | September 30, 2022 at 1:02pm CDT

The Seattle Mariners have selected the contract of catcher Brian O’Keefe from Triple-A Tacoma, reports Ryan Divish of the Seattle Times (Twitter link). In a corresponding move, M’s catcher Curt Casali has been placed on the paternity list.

This will be the first major league action for O’Keefe, age 29, who was drafted in the seventh round by the Cardinals in 2014. After spending five seasons in St. Louis’s system, O’Keefe was picked by Seattle in the 2019 Rule 5 minor league draft. He spent two years in the Mariners farm system before electing free agency at the conclusion of the 2021 season, where he eventually agreed to stay with the M’s on a minor league deal. With Casali out of action for at least 24, but no more than 72 hours, O’Keefe will join the big league club for the first time in his nine seasons as a pro.

O’Keefe has spent all of his 2022 campaign at Triple-A Tacoma, where he has had one of his finest minor league seasons. Thus far, he has hit 13 home runs and posted a productive .253/.330/.449 slash in 352 plate appearances. More than seventy-five percent of O’Keefe’s 2022 appearances for Tacoma have been at catcher, where Baseball Prospectus rates him as an excellent framer, with the rest coming as a designated hitter.

Casali is all but assured to rejoin the Mariners as soon as his time on the paternity list ends. If Seattle is going to keep O’Keefe on the active roster beyond Casali’s return, they will have to make room for him. The M’s 40-man roster is currently full, and the only obvious 60-day IL candidate is lefty reliever Ryan Borucki, who has already been out since August 8th.
