Upton, Morneau and Rizzo have each collected more than three million votes in this tight battle to gain a spot on the NL's All-Star roster.
"It's always special to be among the best players in the game, and just to be there and be part of the festivities," said Upton, who participated in the 2009 and '11 All-Star Games. "Any time you get the opportunity, you have to enjoy it. We'll see what happens."
