Vieira was optioned to Triple-A Tacoma on Tuesday.
The Mariners needed room on the roster for Tuesday's starter, Andrew Albers, and Vieira was the resulting roster casualty. He looked sharp in his big-league debut, so he'll likely be back with the Mariners at some point later in the year. For now, he'll head back to Triple-A, where he owns a 3.18 ERA in 11.1 innings.
Vieira fired a scoreless ninth inning in Monday's 11-3 loss to the Orioles.
The flamethrowing reliever's first majors appearance was one of the few highlights for the Mariners on an otherwise miserable night. Vieira has regularly touched triple digits on the radar gun in the minors and replicated the feat during Monday's 10-pitch outing. While it remains to be seen if he'll stick with the big-league club for the balance of the campaign, the 24-year-old undeniably brings an abundance of strikeout potential.
Vieira was recalled from Triple-A Tacoma on Monday.
Reliever promotions don't normally justify much fanfare, but an exception can be made for Vieira, who has routinely hit triple digits on the radar gun during stops at Double-A Arkansas and Tacoma this season. While the 24-year-old hasn't been able to use his premium heat to generate as many strikeouts (45 in 47.2 innings in the minors) as one would expect, his raw skills alone give him a chance to eventually make a major impact at the back end of the Mariners bullpen. It's not expected that he'll be ticketed for high-leverage duties right away, however, as Vieira will first have to prove he's worthy of a spot on the active roster before manager Scott Servais turns to him in key situations.
Vieira notched his first save in Triple-A Tacoma's win over Sacramento on Sunday, firing a clean ninth inning.
Vieira got 10 of his 15 pitches into the strike zone and as per Rainiers broadcaster Mike Curto, he became the first pitcher to hit 100 mph on the radar gun at Tacoma this season. The 24-year-old made his Rainiers debut on Thursday and surrendered an earned run on one hit over 1.2 innings against Albuquerque while notching three strikeouts.
Vieira was promoted to Triple-A Tacoma on Wednesday, Tacoma broadcaster Mike Curto reports.
The 24-year-old Vieira didn't post overwhelming numbers (3.72 ERA, 1.25 WHIP and 35 strikeouts in 36.1 innings) at Double-A Arkansas, but he remains a high-upside relief prospects thanks to his premium heat. Vieira's fastball regularly hits triple digits on the radar gun, so if he can develop a reliable secondary offering, he could become a fixture in the big-league bullpen for years to come.
