The three RBIs were a new career high for the 21-year-old shortstop, who now has two doubles, a triple, a homer and eight RBIs for Hillsboro. Swanson is coming off an excellent junior season at Vanderbilt in which he was named a first-team All-American for the second time and led the Commodores to the College World Series final.
Swanson was Arizona's second No. 1 overall choice in franchise history. The team selected Justin Upton in the top spot in the 2005 Draft.
