Yaramil Hiraldo Bio
Yaramil Junior Hiraldo is a Dominican professional baseball pitcher who plays for the Baltimore Orioles of Major League Baseball (MLB). A right-handed reliever, he signed with the Orioles organization in late 2024 and reached the major leagues for the first time in May 2025. His road to Baltimore wound through the Arizona Diamondbacks system, several independent league stops, and a season in the Mexican League.
Early Life and Background
Yaramil Junior Hiraldo was born on December 31, 1995, in the Dominican Republic, a country that has produced a deep pipeline of MLB-caliber pitching talent. Growing up in that baseball-rich environment, Hiraldo developed his game on local fields before he was old enough to sign a professional contract. His Dominican roots placed him within a community where professional tryouts and international scouting are a familiar part of the path to professional baseball.
Details about his parents, siblings, and formal education are not publicly documented, but his progression from a teenage prospect to a signed international free agent suggests an early and consistent focus on pitching. Like many Dominican players of his generation, Hiraldo’s formative years were spent sharpening his craft in amateur settings that regularly draw MLB scouts.
Path to Baseball
Hiraldo’s professional career began on June 5, 2018, when he signed with the Arizona Diamondbacks as an international free agent. He made his professional debut that summer in the Dominican Summer League, getting his first taste of organized pro baseball in his home country. The Diamondbacks moved him to the United States for the 2019 season, where he split the year between the Low-A Hillsboro Hops and the Single-A Kane County Cougars.
Across 23 combined appearances in 2019, Hiraldo posted a 2–1 record with a 1.01 earned run average and 32 strikeouts in 35 2/3 innings, numbers that marked him as a promising bullpen arm. He did not play in 2020 after the minor league season was canceled because of the COVID-19 pandemic. Returning to Hillsboro in 2021, now a High-A affiliate, he worked 19 relief outings and recorded a 4.13 ERA with 25 strikeouts and nine saves. The Diamondbacks released him on March 26, 2022, opening the next chapter of his career.
Yaramil Hiraldo Career
Early Career (2018–2021)
Hiraldo’s first four professional seasons were spent entirely within the Arizona Diamondbacks organization. He climbed from the Dominican Summer League to Low-A and Single-A, then reached High-A Hillsboro in 2021, a steady ascent through the lower levels of the minors. His most impressive developmental line came in 2019, when his 1.01 ERA and heavy strikeout totals across two affiliates established him as a relief prospect worth tracking.
After the canceled 2020 campaign and a 2021 season in which he picked up nine saves, Hiraldo was released during spring training in 2022. The transaction sent him looking for opportunities outside the affiliated system and set up a journey through independent ball and the Mexican League before he could return to an MLB organization.
Independent League Stops (2022–2023)
On April 20, 2022, Hiraldo signed with the Lexington Legends of the Atlantic League of Professional Baseball. He made 50 relief appearances for Lexington, going 0–1 with a 5.83 ERA and 78 strikeouts in 54 innings before being released on September 18. The heavy workload gave him a chance to stay active and continue developing, even as his results were uneven.
He returned to the Atlantic League in 2023, first signing with the Charleston Dirty Birds on July 24. In 11 appearances for Charleston, Hiraldo posted a 1–0 record and a 1.64 ERA with 11 strikeouts and five saves across 11 innings, a sharp bounce-back that showed his best stuff. On September 1, 2023, he was traded to the Staten Island FerryHawks, where he wrapped up the year with a 1.29 ERA, eight strikeouts, and two saves in seven innings. The late-season form across both clubs helped rebuild his profile.
Caliente de Durango (2024)
On May 26, 2024, Hiraldo signed with the Caliente de Durango of the Mexican League, taking his career outside the United States for the first time. The stint proved to be his most dominant run as a professional. In 24 appearances for Durango, he went 3–0 with a 2.05 ERA and 27 strikeouts across 22 innings, numbers that drew renewed attention from affiliated clubs.
Baltimore Orioles Era (2024–Present)
On October 31, 2024, Hiraldo signed a minor league contract with the Baltimore Orioles, returning to an MLB organization after more than two years away from affiliated baseball. He opened the 2025 season in the Orioles’ farm system, working with the Triple-A Norfolk Tides and also appearing for the High-A Aberdeen IronBirds and the Double-A Chesapeake Baysox.
On May 24, 2025, the Orioles selected Hiraldo to the 40-man roster and promoted him to the major leagues for the first time. He made his MLB debut on May 27 against the St. Louis Cardinals. Before throwing his first pitch, he was called for a pitch clock violation, but he recovered to strike out Iván Herrera for his first career strikeout, a memorable first appearance in the big leagues.
Driving Style and Strengths
Hiraldo works exclusively out of the bullpen as a relief pitcher and has the profile of a late-inning arm, with extensive experience closing games during his independent and Mexican League stints. His best results have come when he is generating swings and misses at a high rate, as shown by his 78 strikeouts for Lexington in 2022 and his strong strikeout-to-inning ratios in 2023 and 2024. The Baltimore organization has used him in short bursts through the minors in 2025, a deployment that fits his power-pitching style.
Notable Events and Milestones
His MLB debut on May 27, 2025, against the St. Louis Cardinals stands as the signature moment of his career so far, complete with the unusual early pitch clock violation and a first career strikeout of Iván Herrera. Reaching the majors after time in the Dominican Summer League, four MLB affiliates, the Atlantic League, and the Mexican League marks one of the more unusual paths to a 40-man roster in recent years.
Yaramil Hiraldo Career Wins
Because Hiraldo is a relief pitcher, his win totals are limited compared with starting pitchers, but his run-prevention numbers tell the story of his career. He owns a professional record of decisions earned across the Diamondbacks system, the Atlantic League, and the Mexican League, with his most productive stretch coming in 2024 at Caliente de Durango.
Minor League and Independent Highlights
Hiraldo’s most effective professional season to date was 2024 with Caliente de Durango, when he went 3–0 with a 2.05 ERA and 27 strikeouts in 22 innings across 24 relief appearances. In the Atlantic League, his sharpest run came in 2023 between Charleston and Staten Island, when he combined for a sub-1.70 ERA with 19 strikeouts and seven saves over 18 innings. His first win in the affiliated minors came in 2019, when he went 2–1 with a 1.01 ERA across Low-A and Single-A.
Other Performances
In 2022 with the Lexington Legends, Hiraldo logged his heaviest workload as a professional, throwing 54 innings in 50 appearances and recording 78 strikeouts despite a 5.83 ERA. His 2021 season at High-A Hillsboro produced nine saves, a sign of the late-inning role that has followed him throughout his career. Each of these stops helped him keep pitching while he worked his way back to an MLB opportunity.

Personal Life
Details about Hiraldo’s marital status, spouse, and children are not publicly confirmed, so those areas are not included here. He has spent much of his professional career moving between the Dominican Republic, the United States, and Mexico.
2025 Season Performance
Hiraldo’s 2025 season began in the Baltimore Orioles minor league system, where he bounced between the Triple-A Norfolk Tides, the High-A Aberdeen IronBirds, and the Double-A Chesapeake Baysox. The work at three levels gave the Orioles a clear view of his relief arsenal as they considered whether to bring him to the majors.
On May 24, 2025, the Orioles added Hiraldo to the 40-man roster and called him up to the major leagues, and he made his MLB debut three days later against the St. Louis Cardinals. Even with the unusual pitch clock violation before his first pitch, he recorded a strikeout of Iván Herrera and looked the part of a major league reliever in his first outing. The debut was the headline result of his 2025 campaign.
Heading into the rest of 2025, Hiraldo is positioned as a depth arm in the Baltimore bullpen, with the chance to carve out a consistent late-inning role if he continues to miss bats. His path from a 2018 international signing to a 2025 MLB debut is already one of the more unusual journeys on the Orioles’ roster, and his performance in the coming months will determine how permanent his place in the major leagues becomes.
