Eduarniel Núñez Bio
Eduarniel Núñez (born June 7, 1999) is a Dominican professional baseball player and pitcher. Núñez has appeared in Major League Baseball with the San Diego Padres and the Oakland Athletics and progressed through the Chicago Cubs farm system after signing as an international free agent in 2017.
Early Life and Background
Eduarniel Núñez was born on June 7, 1999, and is a national of the Dominican Republic. Public records provided here do not list his city of birth or family details; his professional record begins with his signing as an international free agent with the Chicago Cubs on March 15, 2017.
Núñez began his professional career in the Chicago Cubs organization with assignments to the Dominican Summer League and rookie-level Arizona League affiliates. His early seasons in the United States included a mix of starting and relief work as the organization developed his role in the bullpen.
Path to Baseball
Núñez entered professional baseball through the international signing system and moved through the Cubs’ minor league ladder from rookie levels into full-season ball. He spent time with the Arizona League Cubs and the Low-A Eugene Emeralds, facing the standard development arc of international signees working toward upper minors assignments.
Across multiple seasons he saw assignments at Single-A, High-A and Double-A, showing incremental improvement in strikeout production and settling into a relief role by the 2021 season. His sustained performance in the upper minors over 2023 and 2024 positioned him for free agency and a subsequent minor league deal with the San Diego Padres organization late in 2024.
Eduarniel Núñez Career
Early Career (2017–2024)
Núñez signed with the Chicago Cubs on March 15, 2017, and made his professional debut that year in the Dominican Summer League. In 2018 he made 10 starts for the Arizona League Cubs, posting a 1–3 record with a 3.19 ERA and 39 strikeouts in 36 2/3 innings; in 2019 he pitched with the Low-A Eugene Emeralds and recorded a 1–5 mark with a 6.93 ERA and 38 strikeouts in 37 2/3 innings.
The 2020 minor league season was canceled, and Núñez returned in 2021 with the Myrtle Beach Pelicans (Single-A) and South Bend Cubs (High-A), combining for a 1–4 record, a 4.17 ERA, 50 strikeouts and five saves in 45 1/3 innings across 35 appearances. He split 2022 between South Bend and the Double-A Tennessee Smokies, compiling a 5–5 record with a 4.53 ERA, 57 strikeouts and four saves in 41 relief appearances.
Minor League Breakthrough (2023–2024)
In 2023 Núñez continued at High-A South Bend and Double-A Tennessee and posted improved strikeout numbers, finishing the season with a 3–1 record and a 3.11 ERA, tallying 61 strikeouts and one save in 46 1/3 innings over 38 relief appearances. A highlight of that season came on July 6, 2023, when Núñez combined with Michael Arias, Jarod Wright and Frankie Scalzo Jr. to no‑hit the Peoria Chiefs while playing for South Bend.
Núñez followed that with a strong 2024 campaign split between Double-A Tennessee and Triple-A Iowa, producing a 9–3 record and a 3.28 ERA with 64 strikeouts and five saves across 46 total appearances. He elected free agency after the 2024 season and signed a minor league contract with the San Diego Padres organization on November 6, 2024.
San Diego Padres Breakthrough (2025)
Núñez began 2025 with the Double-A San Antonio Missions and was promoted to the Triple-A El Paso Chihuahuas in June. He made seven scoreless appearances for El Paso, recording one win, two saves and 11 strikeouts across 7 1/3 innings, earning a major league call-up in early July.
On July 1, 2025, the San Diego Padres announced Núñez would be promoted to the major leagues to start a game in a doubleheader against the Philadelphia Phillies. In four appearances with San Diego he posted a 3.86 ERA and recorded two strikeouts across 4 2/3 innings before being included in a trade at the end of July.
Athletics Era (2025–Present)
On July 31, 2025, Núñez was traded to the Oakland Athletics as part of a multi-player deal that sent Mason Miller and JP Sears to San Diego. Núñez made his first appearances with the Athletics later that month and recorded his first major league win on August 26, 2025, earning the final out of an extra‑inning victory over the Detroit Tigers.
Across his appearances with the Athletics in 2025, Núñez logged a 1–0 record and a 9.00 ERA with nine strikeouts in eight innings of work over six games. Combined with his work for San Diego that season, his cumulative major league statistics through the 2025 season show a 1–0 record, a 7.11 earned run average and 11 strikeouts.
Driving Style and Strengths
Núñez has developed as a bullpen pitcher with a demonstrated ability to miss bats, as reflected by elevated strikeout totals in the upper minors and brief major league stints. His minor league record shows use as both a late‑inning option and a multi‑appearance reliever, and his collection of saves and strikeout counts indicate his role as a swing‑and‑miss relief arm within organizational bullpens.
Notable Events and Milestones
Key milestones in Núñez’s career include signing with the Chicago Cubs as an international free agent in 2017, participating in a combined no‑hitter on July 6, 2023, and making his major league debut in 2025. His first major league win on August 26, 2025, stands as an early highlight at the highest level of play.
