Watch Rockies vs. Diamondbacks online LIVE stream: "All these games are very important, but at the same time we need to play better baseball," N.L. all-star Carlos Gonzalez told MLB.com. "If we don't pitch and we don't hit, it's difficult to win this way. They're doing the opposite -- they're pitching and they're hitting."

Patrick Corbin was selected to his first all-star game Saturday as well, representing the first-place D-Backs. He is 9-1 with a 2.49 ERA and will be on the hill Sunday against the Rockies.

"I never thought in a million years that I would be an All-Star or even play professional baseball, so just hearing about it is neat," Corbin told MLB.com. "This is only my second year so I don't know too many players in the league, so it will be cool just to meet guys. Being my first time, I don't really know what to expect. I'll just try to take everything in and try to bring back as many souvenirs that I can."

Colorado will throw out veteran right-hander Roy Oswalt. He is 0-3 with a 7.88 ERA since returning to the big leagues.
