Julián Fernández Bio
Julián Antonio Fernández (born December 5, 1995) is a Dominican professional baseball pitcher for the Washington Nationals of Major League Baseball (MLB). A right-handed reliever, Fernández has spent more than a decade moving through international and minor league systems before reaching the major leagues, where he has appeared for the Colorado Rockies, the Los Angeles Dodgers, and the Washington Nationals. His career path has included stops in the Dominican Summer League, several U.S. minor league affiliates, and a winter league season in Mexico.
Born in the Dominican Republic, Fernández signed his first professional contract as a teenager and built his resume through relief appearances at every level of the minor leagues. After years of development, injury rehabilitation, and perseverance, he made his MLB debut in 2021 and has continued to add to his big-league experience into 2025.
Early Life and Background
Julián Antonio Fernández was born on December 5, 1995, in the Dominican Republic. The Dominican Republic has long produced Major League Baseball talent, and Fernández grew up within a baseball culture that emphasizes early skill development and international amateur signings.
Details about his family background, including the names of his parents and any siblings, are not publicly documented in available sources, and information about his formal education has likewise not been published. What is known is that he attracted the attention of Major League scouts while still a teenager and was positioned to begin a professional career at a young age.
Fernández’s earliest exposure to professional baseball came through the Dominican Summer League, the first rung of professional baseball in the Dominican Republic and a common starting point for young international signees. His path to that point was shaped by the Dominican baseball development system, which often channels teenage prospects directly into MLB club academies.
Path to Baseball
Fernández entered professional baseball in July 2012 when he signed with the Colorado Rockies as an international free agent. He made his professional debut in 2013 with the Rookie-level Dominican Summer League (DSL) Rockies, where he posted a 1–1 record and a 7.94 earned run average (ERA) across ten games, getting his first taste of consistent relief work.
Over the next several seasons, Fernández worked his way through the Rockies’ lower-level affiliates. He returned to the DSL in 2014 with a 1–0 record and a 5.60 ERA in 18 relief appearances, and in 2015 he split time between the DSL and the Rookie-level Grand Junction Rockies, combining for a 3–2 record, a 3.55 ERA, and a 1.11 WHIP across 28 games. In 2016, he pitched for the Low-A Boise Hawks, going 1–2 with a 1.17 ERA in 21 appearances out of the bullpen, and in 2017 he advanced to the Single-A Asheville Tourists, where he recorded a 1–2 record, a 3.26 ERA, and 57 strikeouts in 51 games.
On December 14, 2017, the San Francisco Giants selected Fernández from the Rockies organization with the second pick in the Rule 5 draft, signaling that other organizations viewed his relief arsenal as worth protecting on a major league roster. The transaction represented a significant opportunity, but it also marked the start of a challenging stretch in his career.
Julián Fernández Career
Early Career (2013–2017)
Fernández’s earliest professional seasons were spent almost entirely in the Rockies’ rookie-level affiliates, where he developed as a relief pitcher. His progression through the Dominican Summer League, Grand Junction, and Boise gave him experience in high-volume relief roles and allowed him to refine his command against older competition.
His 2017 season with Asheville marked his most advanced work to that point, as he handled 51 appearances while striking out 57 batters and posting a respectable 3.26 ERA. That performance, combined with his Rule 5 selection by the Giants later that winter, suggested he was on track to break into the major leagues within the next year or two.
Colorado Rockies and Injury Setbacks (2017–2022)
Fernández’s Rule 5 selection was followed by a significant setback, as he underwent Tommy John surgery and missed the entire 2018 season. On November 19, 2018, he was claimed off waivers by the Miami Marlins, but he spent the 2019 season on the 60-day injured list while continuing to recover from elbow issues, never appearing in a game that year.
On October 19, 2019, Fernández was removed from the Marlins’ 40-man roster and returned to the Rockies organization. He did not appear in a minor league game in 2020 because the season was cancelled due to the COVID-19 pandemic. In 2021, he pitched for the Double-A Hartford Yard Goats and the Triple-A Albuquerque Isotopes, going 3–2 with a 3.38 ERA across 44 games, and on September 1, 2021, the Rockies promoted him to the major leagues.
Fernández made his MLB debut on September 5, 2021, allowing three earned runs in 1+2⁄3 innings against the Atlanta Braves. He recorded his first MLB strikeout against shortstop Dansby Swanson of the Braves, and he finished the year with 6+2⁄3 innings over six games for the Rockies. He was designated for assignment on June 11, 2022, cleared waivers on June 16, and was sent outright to Albuquerque, where he struggled to a 7.26 ERA across 58 minor league games before electing free agency on October 12, 2022.
Toronto Blue Jays and Mexican League (2022–2024)
On December 29, 2022, Fernández signed a minor league contract with the Toronto Blue Jays and was assigned to the Triple-A Buffalo Bisons to begin the 2023 season. He struggled at that level, posting a 10.61 ERA with five strikeouts in 9+1⁄3 innings across seven appearances, and on May 25, 2023, he was released by the Blue Jays organization.
On January 22, 2024, Fernández signed with El Águila de Veracruz of the Mexican League, where he rebuilt his performance with a strong relief campaign. In 34 appearances for Veracruz, he compiled a 1–1 record, a 1.82 ERA, 43 strikeouts, and 19 saves across 34+2⁄3 innings pitched, becoming a free agent following the season.
Los Angeles Dodgers and Washington Nationals Era (2024–Present)
On December 20, 2024, Fernández signed a minor league contract with the Los Angeles Dodgers and was assigned to the Triple-A Oklahoma City Comets to start the 2025 season. On July 7, 2025, his contract was purchased and he was recalled to the major league roster, pitching in one game for the Dodgers that same day and allowing two runs on two hits in two innings of work. Across 35 games for Oklahoma City in 2025, he posted a 3–0 record, a 3.05 ERA, and 49 strikeouts.
Fernández was designated for assignment by the Dodgers on August 15, 2025, following the team’s acquisition of infielder Buddy Kennedy. On August 17, 2025, he was claimed off waivers by the Washington Nationals, giving him a fresh opportunity in a new organization. On September 27, 2025, Fernández recorded his first career win, tossing a scoreless inning against the Chicago White Sox.
Driving Style and Strengths
Fernández has been used almost exclusively as a relief pitcher throughout his professional career, with most of his appearances coming out of the bullpen in short stints. His lower-level track record in 2016, when he posted a 1.17 ERA at Low-A Boise, and his dominant 2024 campaign with El Águila de Veracruz, where he notched 19 saves, suggest that he can be effective when healthy and working in defined relief roles. His ability to return from Tommy John surgery and continue pitching in affiliated baseball speaks to his durability and resilience.
Notable Events and Milestones
Fernández’s career has been marked by several meaningful milestones, including his Rule 5 selection by the San Francisco Giants in December 2017, his MLB debut with the Colorado Rockies on September 5, 2021, and his first MLB strikeout, which came against Dansby Swanson of the Atlanta Braves. Most recently, on September 27, 2025, he recorded his first career win in a scoreless inning against the Chicago White Sox as a member of the Washington Nationals.
Julián Fernández Career Wins
Fernández’s professional career has been defined more by relief consistency than by overwhelming win totals, in part because of his late MLB debut and the timing of his first big-league victory. After years of organizational movement and injury rehabilitation, he finally secured his first MLB win on September 27, 2025, while pitching for the Washington Nationals.
Major League Baseball Highlights
Fernández’s most notable MLB win came on September 27, 2025, when he tossed a scoreless inning against the Chicago White Sox to earn his first career victory. Across his stints with the Colorado Rockies in 2021, the Los Angeles Dodgers in 2025, and the Washington Nationals in 2025, he has built a growing portfolio of major league relief appearances.
Other Wins and Performances
In the minor leagues, Fernández has accumulated multiple wins across various affiliates, including a 3–2 record with the DSL and Grand Junction combined in 2015, a 3–2 mark across 44 games at Hartford and Albuquerque in 2021, and a 3–0 record with a 3.05 ERA in 35 games for the Oklahoma City Comets in 2025. His 2024 season with El Águila de Veracruz was a highlight, as he converted 19 saves and posted a 1.82 ERA across 34 appearances.
