The Orioles acquired right-hander Eduarniel Núñez from the A’s in exchange for cash, the clubs announced Friday. He’d previously been designate for assignment and has now been optioned to Baltimore’s Triple-A affiliate in Norfolk. To open space on the 40-man roster, the O’s designated another right-handed reliever, Christian Roa, for assignment.
The 26-year-old Núñez was one of four players the A’s received from the Padres in exchange for Mason Miller and JP Sears. Shortstop Leo De Vries headlined the return, with rotation prospects Braden Nett and Henry Baez standing as enticing secondary pieces. Núñez was the “fourth” prospect in the deal but also the most major league-ready of the bunch. He’d already made a very brief MLB debut with San Diego and jumped right onto the Athletics’ roster following the trade.
Last summer, Núñez pitched eight innings with the Athletics and was tagged for eight runs on nine hits, seven walks and a pair of hit batters. He did fan nine batters, but when accounting for all the walks and the pair of batters he plunked, those nine punchouts only represented 23% of the opponents he faced — just barely north of the league average.
Lackluster debut notwithstanding, the A’s surely had some hope that Núñez could turn things around in 2026. That hasn’t happened. Núñez has a respectable 4.61 ERA through 13 2/3 innings (2 1/3 in Double-A, 11 1/3 in Triple-A), but he’s walked 11 of his 67 opponents (16.4%) and plunked another two batters (3%). Since coming to the A’s organization last summer, Núñez has faced 155 batters between the majors and minors. A whopping 19.3% of them have reached base without putting a ball in play, whether by walk or hit-by-pitch. He’s also tossed six wild pitches in a total of 33 1/3 innings.
Beyond that poor command, Núñez has experienced an alarming velocity drop this season. His four-seamer averaged 98.1 mph last year but is at an even 95 mph so far in 2026. Last year’s slider sat 88.5 mph. This year, it’s at 87 mph. Perhaps the Orioles have some mechanical tweaks in mind to get him back on track, but it’s not an encouraging trend. Núñez doesn’t have a full year of service under his belt and is in the second of three minor league option years, however, so the O’s have some time to get him trending in the right direction if they’re willing to keep him on the 40-man roster.
Roa, 27, was with the Marlins last year and signed with the Astros as a minor league free agent after being outrighted by Miami. He was briefly called to Houston’s big league roster but was quickly designated for assignment and claimed by the Twins. Minnesota optioned Roa to Triple-A and wound up designating him for assignment themselves not long after. The Orioles claimed him earlier this week, but it’ll be another potentially abbreviated stay in a new organization for Roa.
The No. 48 overall pick out of Texas A&M back in 2020, Roa is a hard-throwing righty who’s yet to break through and establish himself in the majors. He’s drawn praise for a plus slider and average or better fastball and changeup over the years, but he’s regularly received 30 and 40 grades (on the 20-80 scale) for his command along the way. Roa has pitched to a 4.56 ERA in parts of four Triple-A seasons, fanning 25.5% of his opponents there but also issuing walks at a dismal 14% clip.
This is already his third DFA of the season. The Orioles will either trade Roa, place him on outright waivers or release him in the days ahead. His DFA will be resolved within a maximum of one week.
