33 Edwin Jackson SP

Jackson allowed two earned runs on three hits and four walks across 4.2 innings in Triple-A Las Vegas' loss to Fresno on Friday. He struck out four.

Jackson worked up to 102 pitches, getting 65 of them into the strike zone. The veteran right-hander is with the Aviators in order to get stretched out after not having had the benefit of a spring training. Susan Slusser of the San Francisco Chronicle reports that there's a possibility Jackson could slide into the major-league rotation during the coming week, although that won't likely be decided for several days.

Jackson will report to Triple-A Las Vegas on Wednesday, Julian McWilliams of The Athletic reports.

Jackson will move to Triple-A after striking out nine batters across five innings of two-run ball in a start for High-A Stockton over the weekend. The veteran right-hander is expected to get up to speed with Las Vegas before ultimately joining the big club. Across 17 starts with the A's last season, Jackson posted a 3.33 ERA, 1.22 WHIP and 68:37 K:BB in 92 innings.

Jackson is set to make a start at Single-A Stockton on Sunday, Susan Slusser of the San Francisco Chronicle reports.

After signing a minor-league deal on April 10, Jackson has slowly gotten stretched out. He participated in extended spring training and also threw a sim game earlier this week. His start Sunday represents the next step in getting up to speed so his role with the big-league club can be determined.

Jackson threw a simulated game in the team's spring facility in Arizona on Tuesday, Martin Gallegos of MLB.com reports.

Jackson has been prepping for an eventual short-term assignment at Triple-A Las Vegas. Tuesday, the veteran right-hander threw approximately 70 pitches, a solid workload that should go a long way toward stretching him out. Jackson is eventually expected to be utilized at the big-league level at some point this season after going 6-3 with a 3.33 ERA across 17 starts in 2018.

Jackson, who signed a minor-league deal with the Athletics on Wednesday, is heading to extended spring training in Arizona to start bullpen sessions, Dave Sessions of MLB.com reports.

The veteran right-hander will use his time in Arizona to begin acclimating his arm to the rigors of the season after not having participated in any spring training. The plan is for Jackson to eventually make his way to Triple-A Las Vegas and stretch out with some starts in anticipation of a callup at some point this season. Jackson was a key figure in an injury-riddled Athletics rotation last season, going 6-3 with a 3.33 ERA across 17 starts.
