Wilson spent the summer hitting leadoff and playing second base with Colorado’s minor-league affiliate, the Class A Tri-City Dust Devils.
The Rockies used a pick in the supplemental round to take the 18-year-old Tago. This was a compensation selection the team received for losing All-Star righty Jason Marquis to the Washington Nationals in the offseason.
Tago was 10-3 with a 2.77 ERA for Dana Hills High School in Dana Point, Calif., last year.
