Attended Stanford University and was an All Pac-12 First Team Outfielder in 2014. Was the Dodgers 44th selection in the 2011 First-Year Player Draft, but did not sign. Raised in Jacksonville, Florida, the grandson of former Jacksonville mayor Ed Austin, a gregarious politician and attorney. During his mayoral term, from 1991-95, the city was awarded the 30th NFL franchise (the Jaguars). He was also the state attorney for almost 20 years. There is Ed Austin Regional Park, a 144-acre park in Jacksonville. The Office of the State Attorney is housed in the Ed Austin Building. His portrait hangs in the Duval County Courthouse. In addition, a bronze statue in Jacksonville's Northbank Riverwalk honors Austin's late grandmother, Patricia Austin, for her volunteer and charity. Was considered the top baseball prospect in Florida until he broke his ankle playing Frisbee and missed his senior season. He considers his ankle injury a blessing in disguise because of how much he now values his college experience. He studied Science, Technology and Society as integrated-studies major. He is about a dozen credits short of graduating. Involved with the following organizations: Giants Community Fund - Education Day and MLB Buses for Baseball.
