Sadler announced his retirement on his personal X account Wednesday.

EDGE Analysis

Sadler made his MLB debut in 2014 and spent parts of six seasons in the majors. He put together impressive campaigns in 2019 and 2021 as a traditional low-leverage reliever, though a shoulder injury ultimately derailed his career.

Sadler (shoulder) announced via his personal Twitter account that he will join Triple-A Tacoma on Tuesday for his season debut with the affiliate.

EDGE Analysis

After re-signing with the Mariners on a minor-league deal in December, Sadler opened the season on Tacoma's IL while he continued his recovery from March 2022 shoulder surgery. He was cleared to begin a rehab assignment in the lower rungs of the minors following the All-Star break and now looks like he'll be activated from Tacoma's 60-day IL on Tuesday after he struck out six while allowing three earned runs in 3.1 innings over four appearances between High-A Everett and the rookie-level Arizona Complex League. Sadler is just two seasons removed from churning out a 0.67 ERA and 0.72 WHIP in 42 relief appearances with the Mariners, and if he can rediscover some semblance of his pre-injury form at Tacoma, he could be in the mix for a late-season return to the big leagues.

Sadler (shoulder) is scheduled to face live hitters next week in the Arizona Complex League, the team's official site reports.

EDGE Analysis

The right-hander, who last pitched in 2021 due to his shoulder issues, appears to finally be inching closer to returning to game action. Mariners general manager Justin Hollander noted Tuesday that Sadler will proceed to Triple-A Tacoma after his upcoming live batting practice session in the AZL and either initiate a rehab assignment or be activated to the Rainiers' roster at that point. If all continues without setbacks, Sadler could certainly be a candidate to pitch in the big-league bullpen again before the end of the season.

Mariners general manager Justin Hollander said last week that he expects Sadler (shoulder) to be ready to resume pitching in games around the All-Star break, MLB.com reports. "He's made a lot of progress since we shut him back down, so he's feeling better, and we're hopeful that he will be back and be able to avoid a second surgical procedure," Hollander said of Sadler.

EDGE Analysis

Since turning in a 0.67 ERA and 0.72 WHIP over 40.1 innings with the Mariners during the 2021 season, Sadler hasn't pitched in affiliated ball while recovering from March 2022 surgery on his right shoulder. The right-hander was cleared to face hitters in spring training but appeared to suffer a setback at some point shortly thereafter, as he didn't resume a throwing program until last week. Because he'll essentially have to go through spring training all over again, Sadler is likely a few weeks away from throwing live batting practice, and more than a month away from heading out on a minor-league rehab assignment. Sadler is on a minor-league deal and is currently residing on Triple-A Tacoma's 60-day injured list.

Sadler (shoulder) has resumed throwing, Ryan Divish of The Seattle Times reports.

EDGE Analysis

Sadler was shut down for a while after spring training, but the time off appears to have helped, and the Mariners are hopeful he will avoid another procedure on the shoulder he had surgically repaired in March of 2022.

The Mariners reassigned Sadler (shoulder) to minor-league camp Sunday.

EDGE Analysis

Sadler was one of the majors' top relievers in 2021 after producing a 0.67 ERA and 0.72 WHIP in 40.1 innings out of the Seattle bullpen, but his future in the big leagues is in flux while he works his way back from the right shoulder surgery he underwent last March. The 32-year-old has resumed mound work and could soon be ready to face hitters, but he may still be a couple weeks away from reporting to a minor-league affiliate to test himself in a game setting.

Sadler (shoulder) completed his first live bullpen session of the spring Friday, Shannon Drayer of Seattle Sports reports.

EDGE Analysis

Sadler is working his way back from a shoulder injury that sidelined him for the entire 2022 season. The right-hander was dominant in 2021 with a miniscule 0.67 ERA over his 40.1 innings of work, and if healthy, he should be a bridge to Paul Sewald and Andres Munoz for the 2023 campaign. Because of his missed time off, however, there's a good chance Sadler won't be ready until after Opening Day.

Sadler (shoulder) and the Mariners agreed Wednesday on a minor-league contract, Jon Heyman of the New York Post reports.

EDGE Analysis

Seattle non-tendered Sadler earlier this offseason, with the 32-year-old reliever choosing to elect free agency soon thereafter. He'll rejoin the Mariners on a deal that presumably includes an invitation to spring training, but it's unclear if Sadler will be ready to go by the time pitchers report to camp in February. After he was one of the majors' top setup men in 2021 with an 0.67 ERA, 0.72 WHIP and 37:10 K:BB over 40.1 innings, Sadler missed the entire 2022 campaign while recovering from the right shoulder surgery he underwent in late March. Sadler isn't a safe bet to reclaim the velocity and command he displayed pre-surgery and may not resurface as a viable MLB reliever.

Sadler (shoulder) cleared waivers Wednesday and elected free agency.

EDGE Analysis

After he was arguably one of MLB's top relievers in 2021 -- he turned in an 0.67 ERA and 0.72 WHIP in 40.1 innings with Seattle -- Sadler went unclaimed by baseball's other 29 teams when the Mariners exposed him to waivers earlier this week. The lack of interest is most likely due to Sadler's uncertain health, as the right-hander missed the entire 2022 campaign after undergoing shoulder surgery last March. It's unclear if Sadler will be back to full strength ahead of spring training, and whenever he gets a clean bill of health, he may need to hold a throwing showcase if he wants to land anything more than a minor-league deal in free agency.

Sadler (shoulder) was transferred to the 60-day injured list Wednesday, Ryan Divish of The Seattle Times reports.

EDGE Analysis

Sadler's placement on the 60-day IL is simply procedural, as the right-hander had already been ruled out for the season after undergoing shoulder surgery in late March. Wednesday's move helps to make room on the 40-man roster for Matt Koch, whose contract was selected from Triple-A Tacoma.
