Early Life and Background
Austin Thomas Slater was born on December 13, 1992, in Jacksonville, Florida. He grew up in the same city and attended The Bolles School, where he played for the school’s baseball team during his early years. His grandfather, Ed Austin, served as the Mayor of Jacksonville from 1991 to 1995, and Slater was named after him. The strong ties to Jacksonville shaped his early connection to the sport and to his community.
During his senior year at The Bolles School, Slater suffered a broken ankle while playing frisbee, which kept him off the baseball diamond for that final season. Despite the injury setback, he was selected as a shortstop by the Los Angeles Dodgers in the 44th round of the 2011 MLB draft. Rather than sign professionally, Slater chose to continue his baseball development at the collegiate level, a decision that helped him mature as a player before joining the professional ranks.
Path to Baseball
Slater enrolled at Stanford University, where he played three seasons of college baseball for the Stanford Cardinal. Over 113 career games with the program, he batted .310 while recording five home runs and 72 runs batted in. His consistent performance at Stanford positioned him as one of the more polished college hitters available in his draft class.
During the summers of 2013 and 2014, Slater gained valuable experience with the Hyannis Harbor Hawks of the Cape Cod Baseball League. He was named a league all-star in 2013, an honor that highlighted his offensive ability against top amateur competition. Following his junior year at Stanford, the San Francisco Giants selected Slater in the eighth round of the 2014 MLB draft. He signed with the Giants for a $200,000 signing bonus, officially beginning his professional career.
