The Athletics released Guerra on Aug. 5.

EDGE Analysis

Signed to a minor-league deal this past season, Guerra spent the first half of the 2023 campaign completing his recovery from April 2022 Tommy John surgery. He began a rehab assignment in the rookie-level Arizona Complex League in late June before returning from Triple-A Las Vegas' 60-day injured list in early July. He made just three appearances for Las Vegas before returning to the 7-day IL on July 17 and then being cut loose three weeks later. The 34-year-old reliever has previously made 134 MLB appearances, but none since 2021.

Triple-A Las Vegas placed Guerra on its 7-day injured list July 17 with an unspecified injury.

EDGE Analysis

After completing his recovery from April 2022 Tommy John surgery, Guerra made his season debut for Las Vegas on July 4. The right-hander made three relief appearances before returning to the IL two weeks later, though it's unclear if he was deactivated due to a setback with his surgically repaired elbow or because of an unrelated injury.

Guerra signed a minor-league contract with the Athletics on Monday.

EDGE Analysis

Guerra was a fairly prominent contributor out of the Oakland bullpen in 2022, maintaining a 4.11 ERA and 1.11 WHIP across 65.2 innings. However, he was non-tendered by the club earlier in the offseason and will now have to earn back his spot on the 40-man roster.

The A's declined to tender Guerra (elbow) a contract for 2023.

EDGE Analysis

Guerra underwent Tommy John surgery in April and missed the entire 2022 season. The righty is a journeyman at 33 years old, but he pitched well for the A's in 2021 (4.11 ERA, 1.11 WHIP) and there will likely be many teams interested in seeing how he looks post-surgery.

Guerra underwent reconstructive surgery on the UCL in his right elbow Wednesday, Matt Kawahara of the San Francisco Chronicle reports.

EDGE Analysis

The A's announced Guerra's elbow procedure last week, but it wasn't previously specified as Tommy John surgery. The 32-year-old will miss the rest of the season and likely the first half of the 2023 campaign while going through his recovery and rehab.

Guerra will undergo elbow surgery April 13, Matt Kawahara of the San Francisco Chronicle reports.

EDGE Analysis

Guerra experienced forearm tightness in late March and was later diagnosed with a UCL injury. The specifics of his procedure are still unclear. If he has to undergo Tommy John surgery, he won't be back until the middle of next season, though it's possible he'll undergo a different surgery with a shorter recovery timeline.

Guerra was placed on the 60-day injured list Thursday due to a sprained right MCL, Matt Kawahara of the San Francisco Chronicle reports.

EDGE Analysis

Guerra will require surgery to address his UCL injury, and he'll miss at least the first two months of the season. The exact nature of his procedure hasn't yet been revealed, so a timetable for his return is unknown.

Guerra (forearm) will undergo surgery that will force him to begin the season on the injured list, Martin Gallegos of MLB.com reports.

EDGE Analysis

Guerra recently received a second opinion on his forearm tightness, and he'll be forced to miss time due to his procedure. While a timetable for Guerra's return hasn't yet been revealed, Domingo Acevedo, Sam Moll and A.J. Puk are candidates to take on setup duties to begin the regular season.

Manager Mark Kotsay said Thursday that Guerra (forearm) will receive a second opinion, Matt Kawahara of the San Francisco Chronicle reports.

EDGE Analysis

Guerra was evaluated for forearm tightness Tuesday, but he'll get an additional diagnosis before the team determines the next steps in his recovery process. The right-hander was in line to serve as one of the team's top setup men in front of closer Lou Trivino to begin the regular season, but his early-season availability will likely depend on the results of his second examination.

Guerra is considered day-to-day after he experienced forearm tightness coming out of his Cactus League debut Wednesday, Matt Kawahara of the San Francisco Chronicle reports.

EDGE Analysis

The Athletics have paused Guerra's throwing program for the time being, with a decision on his next steps likely coming Tuesday, when he's scheduled to be re-evaluated. If he moves past the forearm issue and is deemed ready to go for Opening Day, Guerra is expected to serve as one of the main setup men for Lou Trivino, who is the most likely candidate to begin the season as the Athletics' closer. In 53 appearances for Oakland last season spanning 65.2 innings, Guerra submitted a 4.11 ERA, 1.11 WHIP and 62:20 K:BB.
