The Mariners designated Chargois for assignment Tuesday, Daniel Kramer of MLB.com reports.
With Austin Shenton joining the organization Tuesday via a trade with the Rays, Chargois will end up as the odd man out of the Mariners' 40-man roster. The 33-year-old was extremely effective out of the bullpen in 2024, posting a 2.23 ERA and 1.02 WHIP across 36.1 total innings between Miami and Seattle, so there could be a handful of teams bidding for his services via waivers.

Mariners' Austin Shenton: Traded to Seattle
Rotowire
The Rays traded Shenton to the Mariners on Tuesday in exchange for cash, Daniel Kramer of MLB.com reports.
After making his MLB debut and appearing in 19 games for the Rays in 2024, Shenton will now reunite with the organization that originally drafted him back in 2019. The 26-year-old infielder slashed .258/.361/.497 with 20 home runs and 65 RBI across 363 minor-league plate appearances last season, and he will likely remain an organizational depth piece upon moving to Seattle. JT Chargois was DFA'd in a corresponding move.

Mariners' Casey Lawrence: Sticking with Mariners
Rotowire
The Mariners signed Lawrence to a minor-league contract Friday, per the MLB's transaction log.
Lawrence participated in spring training for the Mariners this past March, and he'll likely do so again after agreeing to yet another minor-league deal with Seattle. The 37-year-old right-hander spent the entire 2024 regular season with Triple-A Tacoma, registering an 11-11 record over 29 starts with a 5.95 ERA, 1.50 WHIP and 108:48 K:BB over 165 innings.
The Mariners selected Castano's contract from Triple-A Tacoma on Monday, Francys Romero of BeisbolFR.com reports.
He's now protected from the Rule 5 Draft. Castano, 26, held a 4.38 ERA and 108:43 K:BB over 125.1 innings between Double-A Arkansas and Tacoma this season.
Polanco underwent surgery Thursday to repair the patellar tendon in his left knee, Jeff Passan of ESPN.com reports.
Polanco had a career-worst .651 OPS in 2024 while playing through the knee issue, and he's now getting the injury addressed. The second baseman is expected to be ready for spring training, but it remains to be seen which uniform he will be donning in 2025 as the Mariners weigh a $12 million club option or $750,000 buyout.
Mariners' Gregory Santos: Wraps '24 with scoreless efforts
Rotowire
Santos, who was activated from the injured list last Monday, subsequently made two relief appearances during which he fired two scoreless innings while allowing one hit and recording one strikeout.
Santos got back on the bump at the major-league level for the first time since July 31 when he earned his second hold with a scoreless seventh inning in the series opener against the Athletics on Friday. He logged one more frame during Sunday's regular-season finale, getting through the eighth inning on just nine pitches. It was a modest but encouraging season-ending sample for Santos, who didn't make his 2024 debut until July due to a lat strain and then missed nearly two months with a biceps injury. The hard-throwing right-hander played on a one-year deal this season, and it remains to be seen if the Mariners will want to take another look considering Santos logged all of 7.1 innings across eight appearances due to the injuries.
