Jose A. Ferrer Bio
José Alexander Ferrer, born on March 3, 2000, is a Dominican professional baseball pitcher who currently plays for the Seattle Mariners of Major League Baseball (MLB). He has previously played in the major leagues for the Washington Nationals, the organization that originally signed him. A right-handed reliever, Ferrer reached the majors in 2023 and has continued his development as a late-inning option.
Ferrer began his professional career in the Dominican Summer League and worked his way through the Nationals’ farm system before earning a place on the major league roster. After several seasons in the minors, he became a key member of Washington’s bullpen and was later traded to Seattle ahead of the 2026 season.
Early Life and Background
José Alexander Ferrer was born on March 3, 2000, in the Dominican Republic, a country that has produced many prominent Major League Baseball players. Details about his hometown and early family life are not widely documented in public sources, but his path to professional baseball reflects the strong Dominican tradition of young players signing with MLB organizations as teenagers.
Growing up in the Dominican Republic, Ferrer was exposed to baseball from a young age, surrounded by a culture where the sport serves as one of the most popular pastimes. His eventual signing as an international free agent in 2017 marked the formal start of his professional journey, moving him from local play into the structure of a Major League organization.
Path to Baseball
Ferrer signed with the Washington Nationals as an international free agent on July 2, 2017, joining a long list of Dominican prospects who enter professional baseball through this route. He made his professional debut in 2018 with the Dominican Summer League Nationals, recording a 3.60 ERA across 14 relief appearances. That introduction to organized baseball gave him his first taste of consistent competition.
The following year, Ferrer moved to the rookie-level Gulf Coast League, where he pitched in nine games and registered a 2.91 ERA with 24 strikeouts in just over 21 innings. The COVID-19 pandemic cancelled the 2020 minor league season, delaying his progress, but he returned in 2021 with the Florida Complex League Nationals and posted a 2.78 ERA with 47 strikeouts in 17 games. By 2022, Ferrer was climbing quickly, pitching at Single-A Fredericksburg, High-A Wilmington, and Double-A Harrisburg, where he combined for a 2.48 ERA with 78 strikeouts and 11 saves. His strong season earned him a spot in the All-Star Futures Game and a place on Washington’s 40-man roster to protect him from the Rule 5 draft.
Jose A. Ferrer Career
Early Career (2018–2022)
Ferrer’s early professional years were spent entirely within the Washington Nationals’ minor league system. In his first four seasons, he progressed from short-season rookie ball to Double-A, with a canceled 2020 season serving as the only significant interruption. By the end of 2022, he had established himself as one of the organization’s most promising relief prospects, combining strikeout ability with strong ERA marks at every level.
His 2022 campaign stood out as a turning point. Ferrer made 48 combined appearances across three affiliates, recording a 2.48 ERA, 78 strikeouts, and 11 saves over 65 and one-third innings. The Nationals recognized his progress by selecting him to play in the All-Star Futures Game and later adding him to the 40-man roster in November 2022.
Washington Nationals (2023–2025)
Ferrer began the 2023 season in Triple-A with the Rochester Red Wings, posting a 3.83 ERA in 34 appearances before receiving his first major league call-up on June 30, 2023. In 39 relief appearances with the Nationals that year, he went 3–0 with a 5.03 ERA and 25 strikeouts in 34 innings. The debut season gave him valuable experience against big-league hitters and cemented his place in the bullpen picture.
The 2024 season started with a setback, as Ferrer was placed on the 60-day injured list in spring training because of a strain in the teres major muscle in his right shoulder. He was activated on July 19 and went on to make 31 appearances down the stretch, finishing 1–0 with a 3.38 ERA, 25 strikeouts, and one save over 32 innings. In 2025, Ferrer took on a larger role after the Nationals traded closer Kyle Finnegan at the trade deadline, becoming the team’s primary closer. Across 72 appearances, he recorded a 4–4 record, 11 saves, a 4.48 ERA, and 71 strikeouts in just over 76 innings.
Seattle Mariners Era (2026–Present)
On December 6, 2025, the Nationals traded Ferrer to the Seattle Mariners in exchange for catcher Harry Ford and pitcher Isaac Lyon. The move gave Seattle a young reliever with closing experience and offered Ferrer a fresh opportunity in a new organization. He joined the Mariners’ bullpen looking to build on his late-inning track record.
Through games of June 20, 2026, Ferrer had posted a 9–5 record with a 4.08 ERA and 148 strikeouts, showing the strikeout ability that defined his minor league years. His role in Seattle has continued to emphasize high-leverage relief work, and his production has kept him in the team’s regular bullpen plans.

Throughout the minors and majors, he has consistently punched out batters at a high rate, including a combined 148 strikeouts in his work for the Mariners through mid-2026.

The 2025 season was a defining year for José Alexander Ferrer.

Across 72 total appearances, Ferrer recorded 11 saves with a 4.48 ERA and 71 strikeouts in just over 76 innings, showing the durability required of a modern late-inning reliever.

The trade to Seattle created a new storyline, pairing him with a contending American League club and offering him a chance to continue his growth in a higher-leverage environment.
