Spencer Bivens Bio
Spencer Bivens is an American professional baseball pitcher for the San Francisco Giants of Major League Baseball (MLB). Born on June 28, 1994, in State College, Pennsylvania, he made his MLB debut in 2024 after a long journey through amateur, independent, and minor league baseball. His career path from a small-town high school standout to a major league reliever has been one of the more unconventional routes in recent memory.
Standing 5 feet 9 inches tall, Bivens relies on command and resilience rather than overpowering velocity. Through the 2025 season, he had compiled a 7–4 win–loss record, a 3.68 earned run average, and 98 strikeouts in his major league career with the San Francisco Giants.
Early Life and Background
Spencer Bivens grew up in State College, Pennsylvania, a college town best known as the home of Pennsylvania State University. He attended State College Area High School, where he played baseball and developed into a competitive pitcher. The local baseball community helped shape his early approach to the game, and the surrounding Centre County leagues gave him year-round opportunities to stay on the mound.
After high school, Bivens enrolled at Louisburg College, a junior college in North Carolina, where he pitched to a 3.14 ERA as a sophomore in 2014. He transferred to Pennsylvania State University in 2015, fulfilling a dream of pitching for his hometown school. Before he could appear for the Penn State baseball team, however, he failed a drug test and lost his roster spot, a setback that briefly redirected his career.
Two years later, Bivens transferred to Rogers State University, where he spent his final two collegiate seasons. He recorded a 3.21 ERA across 27 appearances for the Hillcats. Following his senior year, he pitched for the Lemont Ducks of the Centre County Baseball League, an amateur league near State College, keeping his arm active while searching for his next opportunity.
Path to Professional Baseball
Bivens went undrafted in the 2018 Major League Baseball draft, the first of several hurdles he would have to clear on his way to the majors. Rather than step away from the game, he signed with the Lions de Savigny-sur-Orge of the Division Élite, a top-level independent league in France. In 75 innings pitched in France, he posted a 2.51 ERA, an impressive showing that earned him the nickname “Mr. Belvedere,” a nod to a vodka brand and a 1980s sitcom.
His international detour was followed by another unusual stop. In February 2020, Bivens signed with Kotlářka Praha of the Czech Baseball Extraliga, but the season was canceled because of the COVID-19 pandemic. He returned to the United States and joined the Steel City Slammin’ Sammies of the newly formed Washington League, going 3–2 with a 3.74 ERA in six games, three of them starts.
Spencer Bivens Career
Early Career (2018–2021)
After his time in France and with the Steel City Slammin’ Sammies, Bivens signed with the Washington Wild Things of the Frontier League on October 13, 2020. The transition to the Frontier League proved difficult, as he struggled to a 7.24 ERA in nine appearances and was released on July 7, 2021.
One day after his release, the West Virginia Power of the Atlantic League of Professional Baseball signed him. His stint there was brief and tough, as he posted a 10.50 ERA in three outings. On July 19, 2021, Bivens was traded to the Gastonia Honey Hunters in exchange for Alexis Candelario. With Gastonia, he made 14 starts, finishing 4–8 with a 7.26 ERA and 62 strikeouts across 74 1/3 innings, and he returned for three scoreless appearances in 2022.
San Francisco Giants Breakthrough (2022–2024)
On May 25, 2022, Bivens signed a minor league contract with the San Francisco Giants organization. He split that season between the Single-A San Jose Giants and the Triple-A Sacramento River Cats, compiling a 3.95 ERA with 48 strikeouts in 27 appearances across the two affiliates.
He opened 2023 with the High-A Eugene Emeralds and was promoted to the Double-A Richmond Flying Squirrels after six games. In 27 appearances for Richmond, Bivens went 5–4 with a 3.69 ERA and 72 strikeouts across 78 innings. He was invited to major league spring training in 2024 and began the year at Triple-A Sacramento, where he recorded a 2.81 ERA with 36 strikeouts and eight saves in 21 games, earning Pacific Coast League Pitcher of the Month honors for May.
On June 16, 2024, Bivens was added to the 40-man roster and promoted to the majors for the first time. In his debut later that day, he earned his first career win, going three innings with four strikeouts and allowing just one hit, a home run by Nolan Schanuel. He finished 2024 with a 3–1 record, one save, a 3.14 ERA, and 37 strikeouts across 48 2/3 innings in 27 games.
Giants Major League Era (2024–Present)
Bivens made the Giants’ Opening Day roster in 2025, cementing his role in the major league bullpen. Over 54 appearances, he went 4–3 with a 4.00 ERA in 81 innings, recording three saves and 61 strikeouts. His reliability in middle relief gave the Giants a dependable arm across a long season.
Following the 2025 campaign, Bivens was optioned to Triple-A Sacramento to begin the 2026 season. The move reflected a crowded major league pitching staff rather than any drop in performance.
Driving Style and Strengths
Bivens works as a reliever who leans on location, pitch mix, and calm in high-leverage situations rather than overpowering velocity. His time bouncing between independent leagues, foreign baseball, and the minor leagues sharpened his ability to adjust quickly, a skill that translates well to a bullpen role where preparation windows are short.
Notable Events and Milestones
His first major league win on debut in 2024, the Pacific Coast League Pitcher of the Month award in May 2024, and the nickname “Mr. Belvedere” earned during his dominant stint in France stand out as signature moments. Each chapter of his career, from State College to Savigny-sur-Orge to San Francisco, has marked a step in one of baseball’s more unusual climbs to The Show.

Family Background and Personal Life

2025 Season Performance
Spencer Bivens’ 2025 season represented his first full year in the San Francisco Giants’ major league bullpen after breaking through late in 2024. He appeared in 54 games, compiling a 4–3 record and a 4.00 ERA across 81 innings. He added three saves and 61 strikeouts, giving the Giants a steady presence in middle relief.
The Giants opened the year with Bivens on the major league roster, a sign of how quickly his stock had risen after a strong 2024 debut. By season’s end, the bullpen had leaned on his ability to log multiple innings when needed, taking pressure off the back end of the relief corps.
Looking ahead, Bivens was optioned to Triple-A Sacramento to open 2026, suggesting the Giants want to keep him stretched out and ready for a return to the majors. His career arc, from independent leagues in France to a stable MLB role, points to continued opportunity whenever San Francisco needs a reliable arm.
