As a youth, Wilson played baseball in a local league in Southern California. His parents brought him to Reggie Smith's baseball clinic to receive further instruction. Wilson then attended Harvard-Westlake High School, where he was twice named a prep school All-American.

Considered a five-tool prospect, Baseball America ranked Wilson the 27th best prospect available in the 2010 Major League Baseball Draft, and he was widely projected to be a first-round draft pick in the 2010 Major League Baseball Draft. Wilson committed to attend Stanford University to play college baseball for the Stanford Cardinal baseball team. Signability concerns led Wilson to fall to the 12th round of the draft, where the St. Louis Cardinals selected Wilson. Despite the Cardinals' efforts to convince Wilson to sign a professional contract, including making an offer equivalent to that given to first round picks, Wilson opted to enroll at Stanford. As a freshman in 2011, Wilson earned an All-Pacific-10 Conference honorable mention after batting.313 with a team-leading four home runs during the regular season. During the summer of 2011, Wilson played summer collegiate baseball for the Harwich Mariners in the Cape Cod Baseball League, winning the league's championship, though he batted only. 204.

He missed significant time during the 2013 season with an elbow injury. Returning from injury in April, Wilson was considered by some a potential first round pick in the 2013 Major LeagueBaseball Draft but was not selected in the first round. He was eventually picked with the 49th overall selection of the second round. Wilson signed with the Mariners, and played for the Everett AquaSox of the Class A-Short SeasonNorthwest League in 2013, batting.241 with six home runs and 27 RBIs. In 2014, Wilson played for the Clinton LumberKings of the Class AMidwest League where he greatly improved, batting.291 with 12 home runs, 54 RBIs, and a.893 OPS. He spent 2015 with the Bakersfield Blaze of the Class A-AdvancedCalifornia League where he posted a.239 average with ten home runs and 48 RBIs.
