The Diamondbacks released Vieira (elbow) on March 27.

EDGE Analysis

Vieira is set to miss the entire 2025 season after undergoing Tommy John surgery earlier in the spring. He'll likely look to catch on with a new organization once he completes his recovery.

Manager Torey Lovullo said Thursday that Vieira (elbow/knee/shoulder) will undergo Tommy John surgery, Mark Feinsand of MLB.com reports.

EDGE Analysis

Vieira reported soreness in his knee, shoulder and elbow Monday -- the last of which seems to be the most severe, as it will require him to undergo Tommy John surgery. The operation will force him to miss the entire 2025 season, and he likely won't be cleared for game action until mid-2026.

Vieira told trainers Monday that he feels discomfort in his right knee, right elbow and right shoulder, MLB.com reports.

EDGE Analysis

The Diamondbacks are planning to have Vieira undergo imaging to determine what the source of the discomfort may be. Vieira played for three teams in 2024, finishing out the season with Arizona.

The Diamondbacks outrighted Vieira to Triple-A Reno on Aug. 2.

EDGE Analysis

Though Vieira remains a member of Arizona's organization after clearing waivers earlier this month, he has yet to pitch for Reno since being cast off the 40-man roster. Reno placed him on its restricted list Aug. 9 for unspecified reasons.

Arizona designated Vieira for assignment Saturday.

EDGE Analysis

The Diamondbacks traded for reliever A.J. Puk on Thursday and now that Puk has reported to the team, Vieira will lose his spot on the 26-man and 40-man rosters. Saturday's move marks the third time Vieira has been designated for assignment this season, and he's fallen to a 5.21 ERA in 38 innings split between Milwaukee, Baltimore and Arizona.

The Diamondbacks claimed Vieira off waivers from the Orioles on Thursday, Theo Mackie of The Arizona Republic reports.

EDGE Analysis

Vieira made just one appearance with the O's before being DFA'd, allowing three earned runs on one hit and four walks while failing to record an out. He'll now join his third organization of the year but will almost certainly be limited to low-leverage situations out of Arizona's bullpen.

The Orioles designated Vieira for assignment Monday.

EDGE Analysis

Vieira's stint in Baltimore was brief and unproductive, as he walked four, allowed three runs and didn't record an out in his lone appearance for the Orioles. It's the second time since late May that Vieira has been designated for assignment, as the move had been made previously by the Brewers before they traded him to Baltimore.

The Brewers traded Vieira and Aneuris Rodriguez to the Orioles on Saturday in exchange for Garrett Stallings.

EDGE Analysis

Vieira was DFA'd by Milwaukee on Monday, but he will once again possess a spot on a big-league roster as he joins the Orioles The 30-year-old reliever posted a 4.97 ERA and 1.54 WHIP across 25.1 innings during his tenure with the Brewers, and he'll likely slide into a low-leverage role in Baltimore's bullpen.

Vieira was designated for assignment by the Brewers on Monday.

EDGE Analysis

Vieira has fanned 25 batters over his 22.1 innings this season, but he's also walked 13 and posted a 5.64 ERA and 1.70 WHIP. The 31-year-old has a big arm, so it's possible he'll draw interest from a team that thinks it might be able to fix him.

Vieira earned his second career save Sunday in a win over the Mariners, allowed two runs on a hit and a walk while striking out five over three innings.

EDGE Analysis

Vieira was called upon to begin the seventh with the Brewers holding a comfortable 10-2 lead. He tossed 50 pitches and struck out five along the way to finish the game and earn a rare save in what was just his fourth major-league appearance since the start of last year.
