Tennessee pitching coach Frank Anderson has informed university administrators of his intention to leave the Volunteers program to join the San Francisco Giants coaching staff, sources told Baseball America. His exact role with the Giants is unclear.

Anderson’s departure continues a stretch of significant change in Knoxville following former head coach Tony Vitello’s move to San Francisco to become the Giants’ manager last month. Tennessee director of pitching development Josh Reynolds is expected to be promoted to pitching coach.

Anderson is regarded as one of the premier pitching developers in college baseball. He served as Oklahoma State’s head coach from 2004-12 and held assistant roles across the country dating back to 1984.

Over his four decades in the college game, Anderson has coached 103 pitchers who were selected in the MLB Draft, including 10 first-round picks. Four of those first-rounders came at Tennessee, where Anderson helped build one of the nation’s most consistent and aggressive pitching staffs. The Volunteers have produced at least three drafted pitchers in each of the last four years, including five selections in 2025.

Anderson was named interim head coach in early October after Vitello left for the Giants. Vitello, 47, reshaped Tennessee into a national power after his arrival in 2018. The Volunteers won their first national championship in 2024, reached the College World Series three times in the past five seasons and set a school record with 61 wins during their title run. Vitello also oversaw a recruiting surge that positioned Tennessee among the top programs in the sport. Following the 2024 season, he signed a five-year contract extension that made him the first college head coach to earn more than $3 million annually.

Tennessee, which promoted former associate head coach Josh Elander to head coach, hired Florida assistant Chuck Jeroloman to fill its previous vacancy.

The Volunteers also lost director of performance Quentin Eberhardt to the Giants this month. He was replaced by former MLB strength coach Keegan Knoll.
