Career
Núñez signed with the New York Mets as an international free agent on October 21, 2016. He made his professional debut in 2017 with the rookie–level Gulf Coast League Mets, posting a 5.24 ERA across 19 games (8 starts). In 2018, Núñez made 11 appearances (7 starts) for the rookie–level Kingsport Mets, registering a 3.79 ERA with 36 strikeouts across $40 1⁄3$ innings pitched.

In 2019, Núñez split the year between the Single–A Columbia Fireflies and High–A St. Lucie Mets, accumulating a 5–4 win–loss record with a 4.39 earned run average and 94 strikeouts in 80 innings pitched. Núñez did not play in a game in 2020 due to the cancellation of the minor league season because of the COVID-19 pandemic.

On December 10, 2020, the San Francisco Giants selected Núñez from the Mets in the Rule 5 draft. On March 15, 2021, it was announced that Núñez had sprained the ulnar collateral ligament in his pitching elbow. On March 18, Núñez was placed on the 60-day injured list after undergoing Tommy John surgery, causing him to miss the entirety of the season. On November 20, the Giants returned Núñez to the Mets.

Núñez returned to action in 2022 with the Double–A Binghamton Rumble Ponies, also playing in three games for St. Lucie. In 23 appearances out of the bullpen for Binghamton, he compiled a 3.49 ERA with 43 strikeouts across $28 1⁄3$ innings pitched. Núñez split the 2023 campaign between Binghamton and the Triple–A Syracuse Mets. In 40 relief outings between the two affiliates, he compiled a 5.53 ERA with 70 strikeouts and 3 saves across 57 innings of work.

On April 9, 2024, the Mets promoted Núñez to the major leagues. Núñez debuted against the Atlanta Braves that same day, pitching two innings in relief of Adrian Houser, and yielding one run.
