Guduan cleared waivers and was outrighted to Triple-A Las Vegas on Friday, per MLB's official transactions log.

EDGE Analysis

The 29-year-old was activated from the injured list and designated for assignment earlier in the week, and he'll remain in the organization after going unclaimed on waivers. Guduan posted a 6.28 ERA, 1.67 WHIP and 5:5 K:BB over 14.1 innings for the A's before landing on the shelf with a strained groin in late May.

Guduan (groin) was activated from the 10-day injured list and designated for assignment by the A's on Tuesday.

EDGE Analysis

The 29-year-old was placed on the 10-day injured list May 28 with a strained groin, and he lost his spot on the 40-man roster after recovering from the injury. Guduan struggled in 11 appearances this season with a 6.28 ERA, 1.67 WHIP and 5:5 K:BB across 14.1 innings.

Guduan (groin) worked around a hit and a walk over a scoreless inning out of the bullpen Saturday in his first rehab appearance for Triple-A Las Vegas.

EDGE Analysis

Guduan was placed on the injured list May 28 with a right groin strain, but his ability to pitch in a game setting a week later suggests he likely won't be on the shelf for long. The 29-year-old lefty posted a 6.28 ERA and 1.67 WHIP in his 11 relief appearances for Oakland prior to being shut down with the injury.

Guduan landed on the 10-day injured list with a strained right groin Friday, Matt Kawahara of the San Francisco Chronicle reports.

EDGE Analysis

Guduan last pitched Tuesday, so the move can be backdated to Wednesday, allowing him to return June 5. Whether or not he'll be able to do so remains unclear. Jordan Weems was recalled in a corresponding move.

Guduan was charged with a blown save Sunday against the Angels after allowing a hit in two-thirds of an inning.

EDGE Analysis

Guduan entered in the seventh with the bases loaded and the Athletics clinging to a one-run lead. He allowed the Angels to tie it up on a sacrifice fly and then gave them the lead on an RBI-single by Jose Iglesias. Neither of the runs scored were charged to him but he was still handed a blown save. The 29-year-old lefty has struggled to a 6.75 ERA, 1.80 WHIP and 5:5 K:BB over 13.1 innings.

Guduan will remain in the Athletics' bullpen after Jordan Weems was sent down Wednesday, Matt Kawahara of the San Francisco Chronicle reports.

EDGE Analysis

Guduan was activated from the 10-day injured list Tuesday but was designated as the 27th man for the twin bill against Minnesota. He didn't pitch in the doubleheader but will be available for Oakland going forward after he allowed eight runs on nine hits and three walks in 2.2 innings to begin the season.

The Athletics activated Guduan (thumb) from the 10-day injured list ahead of Tuesday's doubleheader with the Twins.

EDGE Analysis

Oakland is designating Guduan as the 27th man for the twin bill, so he may only be with the big club for one day before returning to the alternate training site. Before landing on the injured list earlier this month with the sprained left thumb, Guduan was roughed up in his three appearances out of the Oakland bullpen. He gave up eight earned runs on nine hits and three walks over 2.2 innings.

Guduan was placed on the 10-day injured list Tuesday with a sprained left thumb.

EDGE Analysis

He suffered the injury in Monday's game and will now be sidelined for at least 10 days. Guduan had given up eight runs in 2.2 innings through three appearances.

Guduan left Monday's game against the Dodgers with a hand injury, Martin Gallegos of MLB.com reports.

EDGE Analysis

The team trainer went out to the mound to take a look at Guduan's hand with two outs in the ninth, and he was forced to exit the contest. The southpaw can be considered day-to-day until details on the injury surface.

Guduan's contract was selected by Oakland on Tuesday.

EDGE Analysis

Guduan was in camp as a non-roster invitee and was reassigned to minor-league camp Saturday, but it turns out he's won an Opening Day bullpen spot after all. With an 8.03 ERA in 24.2 major-league innings, Guduan is unlikely to pitch in high-leverage situations.
