| Feb 27 2025 | Manager Torey Lovullo said Thursday that Vieira (elbow/knee/shoulder) will undergo Tommy John surgery, Mark Feinsand of MLB.com reports. | ROTOWIRE RECOMMENDS: 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. |

| Jul 27 2024 | Arizona designated Vieira for assignment Saturday. | ROTOWIRE RECOMMENDS: 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. |
|
| Jun 6 2024 | The Diamondbacks claimed Vieira off waivers from the Orioles on Thursday, Theo Mackie of The Arizona Republic reports. | ROTOWIRE RECOMMENDS: 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. |
|
| Jun 3 2024 | The Orioles designated Vieira for assignment Monday. | ROTOWIRE RECOMMENDS: 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. |
|
| May 25 2024 | The Brewers traded Vieira and Aneuris Rodriguez to the Orioles on Saturday in exchange for Garrett Stallings. | ROTOWIRE RECOMMENDS: 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. |
|
| May 20 2024 | Vieira was designated for assignment by the Brewers on Monday. | ROTOWIRE RECOMMENDS: 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. |

| Apr 8 2024 | 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. | ROTOWIRE RECOMMENDS: 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. |
|
| Mar 29 2024 | Vieira is included on the Brewers' 26-man active roster for Friday's season opener versus the Mets. | ROTOWIRE RECOMMENDS: Vieira finished the 2023 season on the injured list due to a right calf strain, but he was fully healthy for spring training and posted a 3.52 ERA and 13:5 K:BB in 7.2 innings during Cactus League play to secure his spot on the Opening Day roster. Though closer Devin Williams (back) is expected to be sidelined for the first two-plus months of the season, Vieira is unlikely to factor into the mix for saves given his limited body of work in the majors and the control issues that he's exhibited at every stop of his professional career. That being said, Vieira brings premium velocity to the table and should be a strong source of strikeouts on a per-inning basis even if he's relegated to a middle-relief role for Milwaukee. |
|
| Sep 18 2023 | The Brewers placed Vieira on the 15-day injured list Monday with a right calf strain. | ROTOWIRE RECOMMENDS: The injury will spell an end to Vieira's season, though unless he's dealing with a Grade 2 or 3 strain that necessitates surgery and/or an extended recovery, the hard-throwing right-hander should be in store for a normal offseason. Vieira received a call-up from Triple-A Nashville earlier this month and saw his first MLB action since the 2019 season. In two appearances out of Milwaukee's bullpen, Vieira struck out two batters over three no-hit scoreless innings. |
|
| Sep 6 2023 | Vieira was selected from Triple-A Nashville on Wednesday. | ROTOWIRE RECOMMENDS: Vieira has spent the entire 2023 season in Triple-A Nashville. In 37.2 innings, the reliever posted a 3.35 ERA and 1.24 WHIP. His last major league appearance came in 2019 with the White Sox and after that he pitched in Japan. In a corresponding move, Clayton Andrews was optioned to Triple-A. |
|
| Jan 12 2023 | Vieira signed a minor-league contract with the Brewers on Thursday, Adam McCalvy of MLB.com reports. | ROTOWIRE RECOMMENDS: The deal includes an invitation to major-league spring training. Vieira, 29, is coming off a successful three-year stint in Japan, where he held a 2.86 ERA and 150:61 K:BB over 125.2 relief innings. He'll compete for a middle relief job in Milwaukee. |

| Jun 24 2018 | Vieira was returned to Triple-A Charlotte on Saturday, Phil Thompson of the Chicago Tribune reports. | Vieira served as the White Sox's 26th man for Friday's doubleheader and did not make an appearance in either game. He has a 4.26 ERA with 43 strikeouts over 31.2 innings for Charlotte this season. |
|
| Jun 22 2018 | Vieira will be up as the 26th man for the White Sox doubleheader against Oakland on Friday, James Fegan of The Athletic Chicago reports. | If Vieira is called upon to pitch in the nightcap, it will be his first appearance of the season and the second of his career. The 25-year-old is a classic relief prospect, with a big fastball and questionable command. He has a 4.40 ERA in 30.2 innings for Triple-A Charlotte this season, striking out an impressive 30 percent of batters while walking a far too high 15 percent. |
|
| Mar 6 2018 | Vieira was optioned to Triple-A Charlotte on Tuesday. | Vieira was a long-shot to crack the White Sox bullpen out of spring training given that he only has 17.2 innings at Triple-A to his name. He has plenty of upside, however. Vieira routinely hits triple digits with his fastball and keeps the ball in the park (never produced an HR/9 above 0.6 in the minors). He may be starting the year in Triple-A, but he could find himself back in Chicago later in the season if he proves himself against the most advanced minor-league hitters. |
|
| Nov 16 2017 | Vieira was sent to the White Sox in exchange for international signing bonus pool money Thursday. | Vieira only appeared in one major-league game for Seattle this past season, striking out one during a clean inning against the Orioles in mid-August. The 24-year-old spent a majority of the year in Double-A, but also pitched in 12 games with Triple-A Tacoma once he received a call-up in July. Vieira has a big arm, and can regularly hit triple digits during his relief appearances. It seems possible that he will start the 2018 season in Triple-A, but he should be a member of Chicago's bullpen in due time. |
