CHICAGO – Cubs first baseman Anthony Rizzo justified the hype Sunday with his first walk-off hit in his early career.

Rizzo drove a pitch into the left-field bleachers for a two-run home run in the 10th inning off St. Louis Cardinals rookie Trevor Rosenthal. He capped off his 3-for-4 day in style and was mobbed by his teammates at home plate after the 4-2 win.

“This is something I’ve always dreamed of doing since I was a little kid,” Rizzo said. “I’ve never done it before. Not in the minors, not in the little league, not ever. So it’s awesome.”
