Trevor McDonald Bio
Trevor Dale McDonald is an American professional baseball pitcher for the San Francisco Giants of Major League Baseball (MLB). Born on February 26, 2001, McDonald has risen through the Giants organization since being selected in the 2019 MLB Draft and has developed into a promising arm in the team’s pitching pipeline. He made his Major League debut in 2024 and has continued to see time in the big leagues in 2025.
Early Life and Background
Trevor Dale McDonald grew up in Lucedale, Mississippi, a small community where high school baseball serves as a focal point of the local sports scene. He attended George County High School, where he developed his skills on the mound and drew attention from Major League scouts. His time at George County helped lay the groundwork for his future in professional baseball.
McDonald was drafted while still a senior in high school, receiving the news during a senior trip to Puerto Rico. The call came in an unforgettable setting, on a beach, marking the start of his professional journey. His family and hometown community in Lucedale later celebrated his achievements, underscoring the supportive environment that helped shape his early career.
Path to Professional Baseball
The San Francisco Giants selected Trevor McDonald in the 11th round of the 2019 Major League Baseball Draft, with the 326th overall pick. That selection launched his path through the minor leagues and put him on a structured development track within the Giants organization. He was viewed as a projectable arm with room to grow.
McDonald made his professional debut in 2019 with the rookie-level Arizona League Giants, pitching four innings in his first appearance. He did not see action in 2020 after the minor league season was canceled because of the COVID-19 pandemic. In 2021, he returned to the field and split time between the Arizona Complex League Giants and the San Jose Giants, posting a combined 2-4 record with a 4.09 ERA as he continued adjusting to professional hitters.
Trevor McDonald Career
Early Career (2019-2021)
McDonald’s earliest professional seasons were defined by steady progression through the lower levels of the Giants system. After his brief 2019 debut in the Arizona League, the canceled 2020 season delayed his development, but he returned in 2021 with the Arizona Complex League Giants and the San Jose Giants. His work that year helped him build the experience needed for higher-level competition.
The 2021 campaign gave McDonald a clearer picture of the adjustments required at each level. He finished with a combined 2-4 record and a 4.09 ERA, numbers that reflected the learning curve of a young pitcher finding his footing. Those innings set the stage for a more productive 2022 season.
Minor League Breakthrough (2022-2023)
McDonald started 2022 with San Jose before earning a promotion to the Eugene Emeralds. Across both stops, he posted a combined 6-3 record with two saves and a 2.31 ERA in more than 90 innings, striking out 102 batters. His 10.2 strikeouts per nine innings rate signaled the emergence of a swing-and-miss profile that excited the Giants’ player development staff.
In 2023, McDonald split the year between Eugene and the rookie-level ACL Giants, recording a 1.33 ERA with 51 strikeouts in 14 games, 13 of which were starts. On November 14, 2023, the Giants added him to their 40-man roster, protecting him from the Rule 5 Draft and signaling that he was a legitimate part of the organization’s future. He was optioned to the Triple-A Sacramento River Cats to begin the 2024 season.
San Francisco Giants Era (2024-Present)
McDonald spent most of 2024 bouncing between Sacramento, the Double-A Richmond Flying Squirrels, Eugene, and the ACL Giants, compiling a 3-7 record and a 4.40 ERA with 78 strikeouts across 86 innings in 23 games, 20 of which were starts. On September 29, 2024, the Giants promoted him to the major leagues for the first time, and he debuted in the season finale against the St. Louis Cardinals, tossing three scoreless innings with one strikeout and one walk.
The Giants optioned McDonald to Triple-A Sacramento to begin the 2025 season, but his strong work in the minors led to another promotion on September 16, 2025. He made his first career start on September 21, 2025, against the Los Angeles Dodgers, pitching six scoreless innings before being removed in the seventh. Five days later, on September 26, McDonald earned his first career win against the Colorado Rockies, allowing three runs on five hits with no walks while striking out 10. He closed 2025 with a 1-0 record, a 1.50 ERA, and 14 strikeouts across 18 innings in three appearances.
Notable Events and Milestones
One of the most meaningful moments of McDonald’s young career came in December 2024, when George County High School retired his number and the city of Lucedale presented him with a key to the city. His first Major League start against the Dodgers and his first career win against the Rockies marked additional milestones, highlighting a rapid rise from a beach-side draft call to a Major League mound.
