As a freshman at LSU, Watson transitioned to the outfield and began playing mainly center field.[3] He started the season as a bench player and did not start his first game until March 11, when he went 3-for-4 with one home run and four RBIs, earning him the starting center field job.[4] He was named the SEC Freshman of the Week on May 8 after going 5-for-10 with four RBIs and a .583 on-base percentage in three games versus South Carolina.[5] Watson finished the season batting .317 with nine home runs, 37 RBIs, and 12 stolen bases in 64 games, earning him a spot on the 2017 Freshman All-SEC Team.[6] In the 2017 NCAA tournament, he batted .333 with five home runs, ten RBIs, four steals, and 12 runs in 12 games,[7] and he was named to the 2017 College World Series All-Tournament team.[8] After the season, Watson was named a Freshman All-American by Perfect Game, Baseball America, Collegiate Baseball Newspaper, and D1Baseball.com.[9][10] That summer, he played in the Northwoods League for the Rockford Rivets where he batted .342 with two home runs, 14 RBIs, four doubles, and 11 runs scored in 38 at-bats, earning him the title of number one prospect in the league.[11]
