Rest-of-Season Projections
Clears waivers
The Athletics outrighted Jackson to Triple-A Las Vegas on Tuesday after he cleared waivers.
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.

Brad Johnson is back for the 2024 season and kicks off his column with a deep dive into the American League West pitching staffs, where in Houston ageless Justin Verlander leads the group.
2023 Fantasy Outlook
After walking 5.6 batters per nine innings across five minor-league seasons, Jackson's 16.3% walk rate as a rookie was no surprise. In fact, it was the worst walk percentage among relievers who pitched at least 40 innings. However, the 28-year-old still managed to put together a solid campaign, compiling a 3.00 ERA (2.77 FIP), 1.27 WHIP and 67 strikeouts across 48 innings. He only gave up one home run all season (0.2 HR/9) and was effective against both right-handed (.188 BA) and lefty swingers (.143). Jackson quickly earned a high-leverage role for the A's, finishing finishing 2nd in the American League and 4th overall with 26 holds. A strained shoulder ended his season in August, but he's expected to be ready for camp and reclaim his role as the A's primary setup man.
