Jonathan Trey Brubaker is an American professional baseball pitcher who currently plays for the San Francisco Giants of Major League Baseball (MLB). Born in New Carlisle, Ohio, Brubaker has built a career spanning multiple organizations, having previously played for the Pittsburgh Pirates and New York Yankees. He made his MLB debut in 2020 after being selected by Pittsburgh in the 2016 MLB Draft. Brubaker has established himself as a reliable starting pitcher capable of logging significant innings and missing bats throughout his professional career.
Early Life and Background
Brubaker was born on November 17, 1993, in New Carlisle, Ohio, to Frank and Teresa Brubaker. His father, Frank Brubaker, played professional baseball as a pitcher in the Minor Leagues, providing young Jonathan with firsthand exposure to the sport at an early age. This family connection to baseball helped shape Brubaker’s path toward a career on the mound.
Brubaker attended Tecumseh High School in his hometown, where he began developing his skills as a baseball player. After high school, he continued his athletic and academic career at the University of Akron, where he played college baseball for the Akron Zips. During his junior season in 2015, Brubaker emerged as a standout starter, compiling a 5-4 win-loss record with a 3.63 earned run average across 15 games started.
Path to Professional Baseball
Brubaker’s strong performance at the University of Akron caught the attention of Major League scouts, leading to his selection by the Pittsburgh Pirates in the sixth round of the 2015 MLB Draft. He signed with the organization for a $200,000 signing bonus and reported to professional baseball that same season. The Pirates viewed Brubaker as a promising arm capable of developing into a productive big league starter.
He made his professional debut in 2015 with the West Virginia Black Bears, where he immediately demonstrated his potential by posting a 6-4 record with an impressive 2.82 ERA over 15 starts. This strong debut season provided the foundation for his climb through the Pirates minor league system and reinforced the organization’s belief in his abilities.
Jonathan Trey Brubaker Career
Pittsburgh Pirates Development Years (2015-2019)
Following his debut with West Virginia, Brubaker continued his progression through Pittsburgh’s farm system. In 2016, he split time between the West Virginia Power and the Bradenton Marauders, combining for a 6-11 record with a 4.44 ERA in 26 total starts. The following season saw him advance to Double-A with the Altoona Curve, where he went 7-6 with a 4.44 ERA across 26 appearances including 24 starts.
The 2018 season marked a significant breakthrough for Brubaker. He began the year with Altoona before earning a promotion to Triple-A Indianapolis in May. Across 28 total starts between both levels, he posted a remarkable 10-6 record with a 2.81 ERA and a 1.26 WHIP. His dominant performance earned him the Pirates Minor League Pitcher of the Year award, and the organization added him to their 40-man roster following the season. Unfortunately, Brubaker’s 2019 campaign was derailed by a strained forearm, limiting him to just six appearances all year.
Pittsburgh Pirates Breakthrough (2020-2022)
Despite the injury concerns, Brubaker made the Pirates Opening Day roster for the shortened 2020 season. He made his MLB debut on July 26, pitching two scoreless innings against the St. Louis Cardinals. Brubaker finished his rookie campaign with a 1-3 record, a 4.94 ERA, and 48 strikeouts over 47 and one-third innings. The experience of competing at the highest level provided invaluable lessons for his continued development.
Brubaker took a significant step forward in 2021, making 24 starts for Pittsburgh. He logged 124 and one-third innings, recording a 5-13 win-loss mark with a 5.36 ERA and 129 strikeouts. The workload demonstrated his durability as a big league starter, even as the win-loss record reflected the challenges of pitching for a rebuilding club. In recognition of his contributions, the Pirates named Brubaker their Opening Day starter for the 2022 season, underscoring his standing within the organization.
During his final season with the Pirates in 2022, Brubaker made 28 starts, matching his career high for appearances. He posted a 3-12 record with a 4.69 ERA while recording 147 strikeouts in 144 innings pitched. Following the season, he agreed to a one-year, $2.275 million contract for 2023, avoiding arbitration. However, Brubaker began that season on the injured list due to forearm and elbow discomfort, ultimately undergoing Tommy John surgery on April 12, 2023, which ended his campaign. He rehabilitated from the procedure and agreed to the same $2.275 million salary for the 2024 season.
New York Yankees Tenure (2024-2025)
On March 29, 2024, the Pirates traded Brubaker and international signing bonus pool space to the New York Yankees in exchange for a player to be named later, who was later identified as Keiner Delgado. Brubaker began his Yankees career by making eight rehab appearances across various minor league levels, working his way back from the Tommy John surgery.
The 2025 season brought new challenges for Brubaker. On February 28, it was announced that he had suffered three fractured ribs while attempting to avoid a line drive during practice. He began the year on the injured list as a result of the injury. After rehabbing with Triple-A Scranton/Wilkes-Barre and other affiliates, Brubaker was activated on June 18. He appeared in 12 games for the Yankees, recording a 3.38 ERA with 10 strikeouts over 16 innings of work. On August 5, New York designated Brubaker for assignment. He cleared waivers and was released on August 7, ending his tenure with the organization.
San Francisco Giants Era (2025-Present)
Following his release from the Yankees, Brubaker signed a minor league contract with the San Francisco Giants organization on August 13, 2025. He reported to Triple-A Sacramento River Cats, where he made three appearances including two starts. In that small sample, he posted a 1-0 record with a 1.64 ERA and seven strikeouts over 11 innings, demonstrating the effectiveness of his comeback from injury.
The Giants were sufficiently impressed that they selected Brubaker’s contract on September 1, adding him to their active roster for the remainder of the season. He appeared in five games for San Francisco in 2025, compiling a 4.26 ERA while striking out 12 batters across 12 and two-thirds innings. Brubaker earned the No. 34 jersey with his new organization, continuing his journey back to full-time MLB action.
Pitching Style and Strengths
Brubaker operates primarily as a starting pitcher who has demonstrated the ability to work deep into games and log significant innings when healthy. His career totals through mid-2026 include a 9-28 win-loss record with a 4.67 ERA and 374 strikeouts across his MLB appearances. He has shown particular effectiveness with his ability to generate strikeouts while maintaining reasonable command, though his win-loss record has been affected by pitching for teams in various stages of rebuilding.
Notable Events and Milestones
Beyond his on-field performance, Brubaker has garnered attention for his personal expressions of faith. On June 12, 2026, Brubaker, along with teammates Landen Roupp and Ryan Walker, wrote the Bible passage Genesis 9:12-16 on their caps during the Giants’ Pride Night event, which featured a rainbow Giants logo. Following the game, all three players received reprimands and warnings from MLB for the gesture. The players’ protest drew criticism from local outlets and fans, particularly given the San Francisco Bay Area’s long-standing connection to the LGBTQ community.
