Fellow Rockies on the ballot include center fielder Charlie Blackmon, who was chosen in peer voting to join Tulowitzki at last year's game in Minneapolis; first baseman Justin Morneau, who represented the Twins as an American League All-Star four times and fell short last year in the Final Vote; and outfielder Carlos Gonzalez, a two-time All-Star.
Also hoping to push for their first All-Star appearances are third baseman Nolan Arenado, who has won NL Gold Glove Awards in both of his first full seasons in the Majors, and second baseman DJ LeMahieu, who entered Tuesday night leading the Majors with a .415 batting average and coming off his first NL Gold Glove Award.
