Jackson threw 1.1 clean innings of relief Sunday against the Dodgers, striking out two.

EDGE Analysis

After fizzling out as the Rangers' closer to open the season and then failing to keep his roster spot with Detroit, Jackson has found his footing with the Mariners since joining the club in September. The veteran right-hander has given up no earned runs in eight of his 10 outings for Seattle, producing a 2.38 ERA, 0.88 WHIP and 10:4 K:BB over 11.1 innings. With prior late-inning experience to boot, Jackson should be an option for high-leverage work during the playoffs.

Seattle selected Jackson's contract from Triple-A Tacoma on Monday.

EDGE Analysis

Jackson will be back in the big leagues with his third different team of the season, following stints with the Rangers and Tigers. Between his two previous stops, the veteran reliever submitted a 4.54 ERA, 1.49 WHIP and 28:24 K:BB across 39.2 innings. He'll likely assume a low-leverage role out of the Seattle bullpen.

Jackson signed a minor-league contract with the Mariners on Thursday.

EDGE Analysis

Jackson elected free agency after being designated for assignment by the Tigers in early August. He'll likely start his time with Seattle at Triple-A Tacoma, but he could contribute to the big-league club in the final weeks of the regular season.

Jackson elected free agency Monday, Evan Woodbery of MLive.com reports.

EDGE Analysis

The veteran reliever cleared waivers after being removed from the Tigers' 40-man roster and will seek a job elsewhere rather than accepting an outright assignment to the minors. Jackson has posted a 4.54 ERA and 28:24 K:BB over 39.2 innings this season between the Rangers and Tigers.

The Tigers designated Jackson for assignment Friday, Chris McCosky of The Detroit News reports.

EDGE Analysis

Jackson inked a contract with Detroit on July 26 and surrendered four runs in 4.2 innings before Friday's DFA. The 33-year-old previously pitched for Texas this season and briefly served as the Rangers' closer, posting a 4.11 ERA over 35 total innings. Assuming he clears waivers, Jackson will likely stay within the Tigers organization.

Jackson tossed two scoreless innings of relief with two strikeouts in Tuesday's 12-2 win over the Diamondbacks.

EDGE Analysis

Jackson made his Detroit debut Sunday and promptly allowed four runs while walking three batters and only retiring two. His second appearance with his new team was much more promising, however, and the righty lowered his season ERA to 4.78. Jackson still projects as a low-leverage arm with the Tigers, and he's unlikely to make a significant fantasy impact.

Jackson signed a one-year, major-league contract with the Tigers on Saturday, Evan Petzold of the Detroit Free Press reports.

EDGE Analysis

Jackson was cut loose by the Rangers on Friday after posting a 4.11 ERA and 1.46 WHIP through 35 innings with the club. It didn't take very long for the 33-year-old righty to find his next gig, however, and he'll likely begin his tenure with Detroit as a middle reliever for the major-league team.

The Rangers released Jackson on Friday.

EDGE Analysis

Jackson was DFA'd by Texas on Wednesday and wasn't claimed off waivers. He's now free to seek an opportunity elsewhere. Jackson was an impactful fantasy asset early this season when he saved eight games over the first month of the campaign, but he eventually lost the closer role in Texas and struggled in his final seven outings with the club, allowing seven runs (six earned) over 7.2 innings.

The Rangers designated Jackson for assignment Wednesday.

EDGE Analysis

Jackson still leads the Rangers with nine saves this season, but he has posted an uninspiring 4.11 ERA, 1.46 WHIP and 24:19 K:BB over 35 innings. The right-hander is under contract at a manageable $1.5 million salary, so he could attract some interest via trade or waivers. Even if he quickly finds a home in a new organization, Jackson is unlikely to earn usage in high-leverage spots out of the bullpen, at least not right away.

Jackson picked up the save Sunday against the White Sox, allowing no hits or walks with one strikeout over a scoreless ninth inning.

EDGE Analysis

Jackson received his first save chance since May 21 as closer Robert Garcia got the day off after throwing in back-to-back games. Jackson cashed in for his ninth save of the campaign, marking his first perfect appearance in five outings. The 33-year-old owns a 3.91 ERA and an 18:11 K:BB over 23 innings in 2025.
