Swanson was one of the last Draft picks still playing this season, as he helped Vanderbilt reach its second straight College World Series final before the Commodores lost to Virginia in three games in the championship series. Swanson led the Commodores with a .335 batting average this season to go along with 15 homers and 64 RBIs in 71 games.
Last year, left-handed pitcher Brady Aiken became just the third No. 1 overall pick in 50 years to not sign when he did not come to terms with the Astros before the deadline.
