The Athletics outrighted Jackson to Triple-A Las Vegas on Tuesday after he cleared waivers.
EDGE Analysis
Jackson lost his spot on Oakland's 40-man roster Saturday, when the Athletics needed to clear room for right-hander Alex Speas after acquiring him from the White Sox. Though he notched 28 holds and four saves for Oakland over the past two seasons, Jackson struggled mightily in spring training to earn a demotion to Triple-A to begin the season. The Athletics elected to designate him for assignment after Jackson failed to show much improvement at Las Vegas; he was touched up for one earned run on two hits and five walks over two innings through his first two appearances in the Pacific Coast League.

Jackson was designated for assignment by the Athletics on Sunday.
EDGE Analysis
It's been a precipitous drop for Jackson in a relatively short period of time, as he recorded 28 holds and four saves while posting a a 2.86 ERA over 73 games for Oakland over the 2022 and 2023 seasons. The right-hander's fortunes began to turn for the worse this spring when he produced a 6.48 ERA in nine Cactus League outings, and they didn't get any better (18.00 ERA, 5.00 WHIP) over three appearances with Triple-A Las Vegas early this minor-league season. Jackson's spot on the 40-man roster was taken up by Alex Speas, who was acquired from the White Sox on Saturday for cash considerations.

The Athletics optioned Jackson to Triple-A Las Vegas on Wednesday.
EDGE Analysis
Jackson missed out on a bullpen spot after allowing seven runs (six earned) over 8.1 innings this spring. The 29-year-old could still eventually fill a leverage role in an unsettled Oakland bullpen.

Jackson (elbow/appendix) has made two appearances for the Athletics thus far during Cactus League play, covering two scoreless innings and striking out a batter while giving up one hit and one walk.
EDGE Analysis
When healthy, Jackson was one of the Athletics' top relievers last season, but he didn't make any appearances after May 16 due to a right flexor tendon strain. He began a minor-league rehab assignment in late July, but he ultimately wasn't activated from the 60-day injured list after he required an emergency appendectomy. Jackson appears to have made a full recovery from the appendectomy and should be in good shape to make the Athletics' Opening Day roster, but it's unclear if he'll be a part of Oakland's unsettled closing situation.

Jackson (elbow) underwent an appendectomy Monday and is without a timeline to resume his rehab program, Martin Gallegos of MLB.com reports.
EDGE Analysis
Jackson has made two minor-league appearances in the past week as he works on returning from a strained elbow, but his recovery from the appendectomy will put a pause on his rehab indefinitely. He struck out four and allowed two earned runs in two innings across the two rehab appearances. The right-hander has been on the injured list since mid-May.

Jackson (elbow) allowed two earned runs on two solo home runs while also recording two strikeouts over one inning in Single-A Stockton's win over Lake Elsinore on Saturday.
EDGE Analysis
Jackson's second rehab outing certainly didn't go as smoothly as the first, when he fired a perfect frame Wednesday. However, Jackson still toughed out a difficult inning and recorded a pair of strikeouts along the way, firing 11 of his 17 pitches for strikes. Despite the somewhat rocky appearance Saturday, Jackson will move up to Triple-A Las Vegas for his next rehab outing Tuesday, per Martin Gallegos of MLB.com.

Jackson (elbow) began a rehab assignment with Low-A Stockton on Wednesday.
EDGE Analysis
Jackson struck out a pair in a perfect inning in his first game action in more than two months. The reliever should move up to a higher affiliate soon and wouldn't appear far off from rejoining the Athletics' bullpen.

Jackson (elbow) threw another bullpen session Saturday, the Associated Press reports.
EDGE Analysis
Jackson also threw a bullpen session the previous Saturday and didn't experience any residual effects, but the Athletics apparently determined he wasn't yet ready to face live hitters. However, if the right-hander's elbow responds well again over the next few days, a live BP session could be the next step in Jackson's recovery.

Jackson (elbow) did not feel any residual effects from Saturday's bullpen session, the team's official site reports.
EDGE Analysis
Jackson reported feeling good Sunday and is now set to face live hitters in a batting practice session as his next step. The right-hander last saw game action May 16, so he projects for a fairly lengthy rehab assignment whenever he reaches that stage of his recovery.

Jackson (elbow) is slated to throw a bullpen session Saturday, the team's official site reports.
EDGE Analysis
The right-hander's absence due to a flexor tendon strain is approaching two months, yet Saturday's planned activity is certainly a step in the right direction. Jackson will eventually be ticketed for a lengthy rehab assignment given how long he's been sidelined, but even that step is still likely weeks away.
