Tanner Bibee Bio
Tanner Hayes Bibee is an American professional baseball pitcher who plays for the Cleveland Guardians of Major League Baseball (MLB). Born on March 5, 1999, he made his MLB debut in 2023 and quickly established himself as a promising rotation arm. He is recognized for his sharp strikeout ability and poise on the mound during his early major league seasons. A product of California State University, Fullerton, Bibee has developed into one of the Guardians’ most dependable starting pitchers.
Early Life and Background
Tanner Hayes Bibee was born on March 5, 1999, and grew up in Southern California. He attended Mission Viejo High School in Mission Viejo, California, where he began developing the pitching foundation that would later carry him to the professional ranks. During his high school years, he showed enough promise to attract college attention from several programs along the West Coast.
After completing high school, Bibee enrolled at California State University, Fullerton, where he played college baseball for the Cal State Fullerton Titans. In 2019, he expanded his summer experience by playing collegiate summer baseball with the Wareham Gatemen of the Cape Cod Baseball League, one of the most respected amateur leagues in the country. He was eligible for the 2020 Major League Baseball Draft but went undrafted, which motivated him to return to Fullerton for his senior year and refine his craft.
Path to Baseball
Bibee’s path back to the draft in 2021 was shaped by perseverance after going undrafted the previous year. His work with the Cal State Fullerton Titans gave him the platform he needed to showcase his improved repertoire, and his summer in the Cape Cod League had already introduced him to high-level competition. These experiences prepared him for the next stage of his baseball career.
The Cleveland Guardians selected Bibee in the fifth round with the 156th overall pick of the 2021 Major League Baseball Draft. The selection validated his decision to return for his senior season and offered him a clear path into professional baseball. He soon began his climb through Cleveland’s farm system with a focus on consistency and strike throwing.

Across 25 starts, he recorded 167 strikeouts in 132 and two-thirds innings pitched, demonstrating the swing-and-miss profile that had defined his amateur career.
That strong minor league performance set the stage for his first major league opportunity.
