Trevor Dale McDonald is an American professional baseball pitcher for the San Francisco Giants of Major League Baseball. Born on February 26, 2001, McDonald developed his craft in Lucedale, Mississippi, before the San Francisco Giants selected him in the 11th round of the 2019 MLB Draft. He climbed methodically through the minor leagues over five seasons before earning his first major league call-up in September 2024. McDonald made an immediate impact at the sport’s highest level, recording his first career win against the Colorado Rockies in September 2025 while striking out 10 batters. His journey from a small-town Mississippi high school to the majors exemplifies dedication and steady progression through professional baseball’s development system.
Early Life and Background
McDonald grew up in Lucedale, Mississippi, where he attended George County High School. His hometown sits in George County in the southeastern part of the state, a region known more for its rural character than its baseball tradition. During his high school years, McDonald developed into a promising pitching prospect, catching the attention of professional scouts. His performance on the mound for George County High School laid the foundation for his eventual selection in the MLB Draft.
McDonald graduated from George County High School in 2019. His baseball career received a significant boost when the San Francisco Giants selected him in the 11th round of the 2019 MLB Draft with the 326th overall pick. Notably, the Giants selected McDonald while he was on a senior trip to Puerto Rico. He received the life-changing call while relaxing on a beach, a moment that marked the beginning of his professional baseball journey. In recognition of his achievements, George County High School retired McDonald’s number in December 2024, and he received the key to the city of Lucedale the same month.
Path to Professional Baseball
After signing with the Giants following his selection in the 2019 MLB Draft, McDonald made his professional debut that same year. He pitched four innings for the rookie-level Arizona League Giants during his first professional season. The brief appearance provided him with initial exposure to professional competition while allowing the organization’s coaches to evaluate his raw stuff and mechanics.
The 2020 minor league season was canceled entirely due to the COVID-19 pandemic, halting McDonald’s development trajectory temporarily. Despite this setback, he returned to action in 2021 with renewed focus. That season, McDonald split time between the Arizona Complex League Giants and the San Jose Giants. He posted a combined record of 2-4 with a 4.09 earned run average across these assignments, demonstrating his ability to compete at the Single-A level while continuing to refine his pitching arsenal.
