Sam Long

Samuel Trenton Long (born July 8, 1995) is an American professional baseball pitcher for the Chiba Lotte Marines of Nippon Professional Baseball (NPB). He has previously played in Major League Baseball (MLB) for the San Francisco Giants, Oakland Athletics, and Kansas City Royals. He played college baseball for the Sacramento State Hornets. He was drafted by the Tampa Bay Rays in the 18th round of the 2016 MLB draft.

In 2018, at 23 years of age, he stopped playing baseball for a year and explored becoming a firefighter, but decided to stick with baseball and made his MLB debut with the Giants in 2021.

High school and college Long was born and raised in Fair Oaks, California.

Long first attended Rosemont High School, for which he played baseball for two seasons. He then attended Del Campo High School in Carmichael, California as a junior and senior. He was named the WAC's Freshman of the Year, and a Louisville Slugger Freshman All-American.

In 2015 he was 6–4 for the Hornets with a 2.81 ERA, and was 2nd in the conference in WHIP (0.892), third in hits per nine innings pitched (6.4), eighth in strikeouts/walk (3.94) and with 63 strikeouts (in innings), and ninth in walks/9 IP (1.6).

In 2016, he was 5–8 with a 3.99 ERA, and was eighth in the conference with 68 strikeouts (in innings). He suffered two herniated disks, but pitched through the injury. He made his professional debut with the GCL Rays, and also played for the rookie ball Princeton Rays, recording a 1–1 record and 3.33 ERA in 11 appearances between the two teams.

He split the 2017 season between the Low-A Hudson Valley Renegades and the Single-A Bowling Green Hot Rods, posting a 2.27 ERA with 29 strikeouts in 31.2 innings pitched across 20 appearances.

On March 22, 2018, on the last day of spring training, Long was released by the Rays organization.

At that point, in lieu of playing baseball which he felt was not going to work out, and uncertain as to what he would do with his future, the 23-year-old Long took EMT classes during the summer, thinking perhaps he would become a firefighter. In the fall he resumed studying for his communications degree at Sacramento State. He spent the 2019 season in Single-A with the Kannapolis Intimidators, pitching to an 8–5 record and 3.06 ERA with 112 strikeouts and a WHIP of 1.041 in 97.0 innings of work. He held batters to a .205 batting average, with 10.4 strikeouts and 2.6 walks per nine innings, and his fastball hit 95 mph.
