Early Life and Background
Austin Thomas Slater was born on December 13, 1992, in Jacksonville, Florida, and he was raised in the same city. He was named after his grandfather, Ed Austin, who served as the Mayor of Jacksonville from 1991 to 1995. Slater attended The Bolles School in Jacksonville, where he played for the school’s baseball team and developed as a young athlete. His senior year was interrupted when he broke his ankle while playing frisbee, and he did not play baseball during that final prep season.
Despite the injury setback, Slater drew early professional interest. He was drafted as a shortstop by the Los Angeles Dodgers in the 44th round of the 2011 Major League Baseball draft. He chose not to sign with the Dodgers, opting instead to continue his baseball development at the college level.
Path to Major League Baseball
Slater played college baseball at Stanford University, where he batted .310 with five home runs and 72 runs batted in (RBIs) across 113 career games during three seasons. He spent his summers playing for the Hyannis Harbor Hawks of the Cape Cod Baseball League in 2013 and 2014, and he was named a league all-star in 2013. His performance on the Cape and at Stanford helped establish him as a polished hitting prospect entering the 2014 draft.
The San Francisco Giants selected Slater in the eighth round of the 2014 MLB draft, and he signed for a $200,000 signing bonus. He began his professional career in the Giants’ farm system that same summer, working his way through the minor leagues before reaching the majors three years later.
