Guilbeau was reassigned to minor-league camp Saturday.

EDGE Analysis

Guilbeau was healthy to begin spring training after missing the end of the 2020 season due to a left shoulder strain. The southpaw made five relief appearances this spring and allowed four hits and three walks while striking out two over 4.2 scoreless innings. Guilbeau should begin the year in the minors. He could join the major-league bullpen at some point in 2021.

Guilbeau (shoulder) is scheduled to pitch in relief in Monday's Cactus League game against the Brewers, Steve Gilbert of MLB.com reports.

EDGE Analysis

Guilbeau finished the 2020 season on the shelf due to a left shoulder strain, but he's faced no restrictions this spring while attending camp as a non-roster invitee. The 27-year-old lefty is a longshot to win a spot in the Diamondbacks' Opening Day bullpen.

Guilbeau (shoulder) cleared waivers and was outrighted to Triple-A Reno, Nick Piecoro of the Arizona Republic reports.

EDGE Analysis

Guilbeau will be a non-roster invitee to major-league camp. He pitched for the Mariners in 2019 and 2020, inducing a 58.2 percent groundball rate over 20 innings, but he saw his strikeout rate drop moving up to the majors and experienced a drop in velocity due to a shoulder injury.

Guilbeau (shoulder) was designated for assignment by the Diamondbacks on Saturday, Steve Gilbert of MLB.com reports.

EDGE Analysis

Guilbeau was claimed off waivers from Seattle in October but won't get to last the full winter on Arizona's roster. His 2.70 ERA in 20 career innings at the highest level could encourage another team to take a chance on him, though that's come with a poor 10:9 K:BB. He also saw his 2020 season cut short due a shoulder strain, which could keep interest suppressed.

Guilbeau (shoulder) was claimed off waivers by the Diamondbacks on Friday.

EDGE Analysis

Guilbeau threw just 7.2 innings for the Mariners this season before suffering a season-ending shoulder strain. He allowed just a single run, though his 3:6 K:BB and 1.83 WHIP suggest that things could have gone far worse. Whether or not the shoulder issue will still be a factor for the lefty heading into spring training remains to be seen.

The Mariners transferred Guilbeau (shoulder) to the 45-day injured list Thursday.

EDGE Analysis

Guilbeau's move to the 45-day IL officially spells an end to the lefty reliever's season after he was shut down over the weekend with a strained shoulder. He made eight appearances during his second season in the majors, giving up one run in 7.2 innings but posting an ugly 3:6 K:BB.

Guilbeau was placed on the 10-day injured list with a strained left shoulder Saturday.

EDGE Analysis

The severity of the injury and Guilbeau's expected return date are not yet clear. The lefty owns a strong 1.17 ERA in 7.2 innings this season, but that's come with a 1.83 WHIP and a 3:6 K:BB.

Guilbeau was recalled by the Mariners on Saturday.

EDGE Analysis

Guilbeau returns to the majors just one day after being sent down, with Nestor Cortes (elbow) landing on the injured list in a corresponding move. Guilbeau has appeared in five games for the Mariners this season, allowing just one run in 5.1 innings, though his 2:3 K:BB is unconvincing.

Guilbeau was optioned to the Mariners' alternate training site Friday.

EDGE Analysis

Guilbeau was effective pitching in low-leverage situations for the Mariners to begin the season, recording a 1.69 ERA with two strikeouts over 5.1 innings across five appearances. However, he'll head to alternate camp since newly-acquired Brady Lail was added to the active roster Friday. Guilbeau has put up solid results over a limited sample in the majors and could rejoin the Mariners' bullpen at some point in 2020.

Guilbeau has fired a pair of scoreless innings during which he's allowed two hits and recorded a strikeout across two appearances since being recalled from the Mariners' alternate training site Tuesday.

EDGE Analysis

The southpaw has been relatively efficient overall, needing 27 pitches to get his six total outs in his pair of outings against the Angels. Guilbeau allowed an earned run on two hits and a walk over an inning to the Astros on July 27 before being optioned to Tacoma, and he could potentially shuttle back and forth a couple more times between the big-league club and the alternate training site during what's left of the season, depending on bullpen needs.
