Rizzo struggled in the early going but then heated up -- he also got an extra 30 seconds of time above the four-minute regulation round by hitting two homers 425 feet or further.
But Donaldson got hot early and hit seven homers in the first couple of minutes before taking a time out. Shortly thereafter, he eliminated Rizzo. Donaldson went on to fall in the semifinals to Cincinnati representative Todd Frazier, who went on to win it all.
Font also throws BP to Bryant, but the rookie picked his father, Mike, to throw to him in the event. Bryant was also bested in the first round, falling to Albert Pujols, 10-9.
Font is experiencing his first All-Star Game presented by T-Mobile since 1997, when he was named to a Minor League honor team. Font, 37, didn't get to participate in that one, though, because he was promoted to the Class A Advanced level.
Font, who primarily helps in the bullpen and with the infielders, said beforehand he likely would be nervous.
"Everybody should be nervous," Font said. "It's not easy -- there's a million people watching us."
