Jonathan Loáisiga Bio
Jonathan Stanley Loáisiga Estrada is a Nicaraguan professional baseball pitcher who is currently a free agent. He previously played in Major League Baseball (MLB) for the New York Yankees, where he spent the majority of his career as a versatile arm out of the bullpen and an occasional starter. Loáisiga made his MLB debut in 2018 and built a reputation as a reliable middle reliever before injuries interrupted his momentum in subsequent seasons.
Born on November 2, 1994, in Nicaragua, Loáisiga grew up surrounded by baseball and developed into one of the most visible Nicaraguan pitchers of his generation. He became the first Nicaraguan to play for the Yankees, carving out a meaningful place in the franchise’s long history.
Early Life and Background
Jonathan Stanley Loáisiga Estrada was born on November 2, 1994, in Nicaragua. He was raised in a family with deep roots in professional baseball, a background that shaped his early interest in the sport. His father, Stanley Loáisiga, played in the Montreal Expos minor league system, while his grandfather was an accomplished professional pitcher in Nicaragua. His brother, Mike, signed with the Los Angeles Dodgers at 17 and played in the team’s minor leagues until 2018.
Growing up in Nicaragua, Loáisiga idolized Dennis Martínez, a fellow Nicaraguan who won 245 games in the major leagues. Martínez’s success provided a tangible example of what was possible for a young pitcher from the country, and his career served as a source of inspiration for Loáisiga as he pursued his own path in professional baseball.
Path to Baseball
Loáisiga signed with the San Francisco Giants as an international free agent on September 23, 2012, beginning his professional career at a young age. He made his professional debut in 2013 with the Dominican Summer League Giants, where he spent the entire season, posting an 8–1 win–loss record with a 2.75 earned run average and 1.11 WHIP in 13 games started. The strong start hinted at his potential, but injuries disrupted his development over the next two years.
Loáisiga did not pitch in 2014 and 2015 due to injuries, and the Giants released him on May 30, 2015. Despite this setback, his early track record was enough to attract the attention of another organization, and he signed with the New York Yankees on February 9, 2016. That signing launched the next and most defining chapter of his career, leading him through the Yankees’ minor league system and eventually to the major leagues.
Jonathan Loáisiga Career
Early Career (2016–2017)
After joining the Yankees organization, Loáisiga began the 2016 season with the Charleston RiverDogs. He pitched only one game before suffering an injury that required Tommy John surgery, a significant setback that cost him most of the season. Despite the injury, the Yankees added him to their 40-man roster after the 2016 season, signaling their confidence in his long-term potential.
Loáisiga returned to action in 2017 and pitched for both the Gulf Coast League Yankees and Staten Island Yankees. He compiled a combined 1–1 record and 1.38 ERA in 11 starts, demonstrating that he had recovered and could once again perform at a high level. The recovery set the stage for his rapid ascent through the minor leagues the following year.
Yankees Breakthrough (2018–2020)
Loáisiga began the 2018 season with the Tampa Yankees of the Low-A Florida State League and earned a promotion to the Trenton Thunder of the Double-A Eastern League after starting the season 3–0 with a 1.35 ERA over four starts. In Trenton, he made six starts, compiling a 4.32 ERA while striking out 32 batters in 25 innings of work. With Yankees starter Masahiro Tanaka injured, Loáisiga was called up to the majors, skipping the Triple-A level entirely.
He made his major league debut on June 15, 2018, pitching five scoreless innings and earning the win. He also became the first Nicaraguan to play for the Yankees, a milestone that carried personal and national significance. He made four starts for the Yankees, pitching to a 3.00 ERA, before being optioned to the Scranton/Wilkes-Barre RailRiders of the Triple-A International League on July 2. He was recalled to the Yankees on September 2 after roster expansion, finishing 2018 with 24+2⁄3 innings pitched for the club. In 2019, he followed it up with 31+2⁄3 innings across 15 appearances, and in 2020, he broke camp with the Yankees as a swing man, starting occasionally while also coming out of the bullpen.
Established Reliever Era (2021–2023)
On April 24, 2021, Loáisiga recorded his first career save against the Cleveland Indians, establishing himself further in a late-inning role. Two months later, on June 25, 2021, he became the first relief pitcher in Yankees history to strike out four batters in one inning, fanning Michael Chavis, Alex Verdugo, J. D. Martinez, and Xander Bogaerts of the Boston Red Sox in the seventh inning. In July 2021, Loáisiga, along with teammates Nestor Cortes and Wandy Peralta, tested positive for COVID-19, leading to a stint on the COVID-19 injured list. He finished the 2021 season with 18 holds, a 2.17 ERA, and 69 strikeouts in 70+2⁄3 innings, his strongest full season in the majors.
In 2022, he went 2-3 with a 4.13 ERA, working primarily out of the bullpen. On May 1, 2023, it was announced that Loáisiga would be out until August after undergoing surgery to remove a bone spur from his right elbow. He was activated from the injured list on August 7, 2023, and logged a 3.06 ERA with 6 strikeouts across 17+2⁄3 innings in 17 relief outings.
Return and Final Yankees Years (2024–2025)
Loáisiga made three scoreless appearances for the Yankees to begin the 2024 season. However, he was placed on the 60-day injured list with a right flexor strain on April 5, 2024. The next day, it was revealed that he had a torn UCL in the right elbow, requiring surgery and prematurely ending his 2024 season. On December 11, 2024, Loáisiga signed a one-year contract to return to the Yankees with a club option for 2026.
In 30 appearances for New York in 2025, he registered an 0-1 record and 4.25 ERA with 25 strikeouts and one save across 29+2⁄3 innings pitched. On August 28, 2025, it was announced that Loáisiga would miss the remainder of the season due to a flexor strain. The Yankees declined his club option on November 5, making him a free agent.
Notable Events and Milestones
One of Loáisiga’s defining moments came on June 15, 2018, when he became the first Nicaraguan to play for the Yankees, debuting with five scoreless innings and a win. He later became the first relief pitcher in Yankees history to strike out four batters in a single inning on June 25, 2021, and he recorded his first career save on April 24, 2021. These milestones underscore his place in both Yankees and Nicaraguan baseball history.
