Basso (1-1) took the loss Sunday, allowing a run on three hits and two walks over 1.1 innings against Kansas City. He recorded no strikeouts.

EDGE Analysis

The 27-year-old opened the game Sunday but couldn't find a rhythm, loading the bases before exiting in the second inning with one out. Tyler Ferguson then allowed an inherited runner to score. Basso didn't make his first big-league appearance of the year until Aug. 27 after dealing with a left shoulder strain and beginning with Triple-A Las Vegas. He managed strong results with a 2.31 ERA across 11 outings and 11.2 innings, though a 1.80 WHIP, 4.07 FIP and 6.9 BB/9 suggest trouble beneath the surface.

Basso will serve as the Athletics' opening pitcher in Sunday's game against the Royals, Martin Gallegos of MLB.com reports.

EDGE Analysis

The Athletics won't have Jeffrey Springs make his normally scheduled start in the season finale, so Basso will take the mound first in what's expected to be a bullpen day. Basso made four starts for the Athletics in 2024 but has worked exclusively as a reliever in 2025. He's eclipsed two innings in just one of his 18 appearances between the majors and minors this season, so he's unlikely to work more than once through the batting order Sunday.

Basso threw a perfect inning with no strikeouts in Saturday's loss to the Pirates.

EDGE Analysis

Basso worked a clean eighth inning Saturday in a game where the Athletics' offense couldn't get going. The left-hander was called up Aug. 27 and has been effective since, tossing nine straight scoreless appearances. It's a small sample, but the 27-year-old's early results are encouraging, especially considering he was primarily used as a starter before this year.

Basso allowed no hits and a walk with no strikeouts over a scoreless inning Wednesday against the Tigers.

EDGE Analysis

Basso made his season debut for the Athletics, tossing a scoreless ninth inning to close out an impressive sweep of the Tigers. The southpaw has spent most of the year sidelined by a left shoulder strain suffered in March, then was optioned to Triple-A Las Vegas upon activation Aug. 11 before being recalled ahead of Wednesday's contest. Though a starter by trade, Basso has been working out of the bullpen since returning from injury.

The Athletics recalled Basso from Triple-A Las Vegas on Wednesday.

EDGE Analysis

With Joey Estes (back) headed to the injured list, Basso will come up from Triple-A to round out the Athletics' pitching staff. The 27-year-old has worked primarily as a starter throughout his career but has transitioned into a relief role since returning from a shoulder injury that kept him on the shelf until Aug. 11. Now back in the bigs, he'll presumably continue to work in middle relief.

The Athletics reinstated Basso (shoulder) from the 60-day injured list and optioned him to Triple-A Las Vegas on Monday.

EDGE Analysis

Basso started the season on the IL due to a left shoulder strain, which flared up during his rehab assignment in June and forced him to be shut down from throwing. He was given the green light to restart his rehab assignment in Triple-A last week, and he will stay in the minors to continue to get stretched out. To make room for Basso on the 40-man roster, the Athletics transferred Austin Wynns (abdomen) to the 60-day IL in a corresponding move.

Basso (shoulder) will resume a rehab assignment with Triple-A Las Vegas on Wednesday, Martin Gallegos of MLB.com reports.

EDGE Analysis

Basso had to be pulled off his initial rehab assignment in mid-June following a setback, but he's now ready to be thrown back into game action. The southpaw has been out all season with a shoulder strain and is likely to require a fairly lengthy rehab assignment before being considered for the Athletics' active roster.

Basso (shoulder) was pulled off his rehab assignment at Triple-A Las Vegas on Wednesday, Martin Gallegos of MLB.com reports.

EDGE Analysis

A left shoulder strain has kept Basso on the injured list all season, though he seemed close to a return after making three rehab appearances in the minors. However, a setback in his recovery puts him at risk of spending even more time on the IL. He's set to be re-evaluated within the next several days, at which point a new timeline for his recovery may be established.

Basso (shoulder) struck out two in a scoreless inning Sunday at Single-A Fresno and could be deployed as a reliever going forward to get him back from the 60-day injured list faster, Martin Gallegos of MLB.com reports.

EDGE Analysis

Basso has started four games so far this season for the A's, but after he looked strong in a single inning Sunday, the club is considering bringing him back as a reliever, per Gallegos. If Basso is able to get through a few more relief appearances, it wouldn't be a surprise to see him back from the 60-day IL within the next few weeks.

Basso (shoulder) will begin a rehab assignment with Single-A Stockton on Sunday, Martin Gallegos of MLB.com reports.

EDGE Analysis

Basso has been sidelined all season with a left shoulder strain and made just two appearances during spring training before the injury, so it will take time for him to build back up. There are spots in the Athletics' rotation to be had, however, so Basso could grab one if he pitches well and gets sufficiently stretched out.
