Pete Alonso will defend his Home Run Derby title in Colorado on July 12.
Alonso, 26, has 11 home runs this season, but he has three career homers in six games at Coors Field in Denver.
"I had so much fun during the first one, so I was like, 'You know what? Let's do it again,'" the New York Mets slugger said. "I just had a blast. It's a really special moment, and as long as I have an opportunity to do it, I want to do it. Because it's something I always dreamt about as a kid. ... It was a dream come true."
