Green led off with a double deep to center that cleared Kincaid's head and later scored on an RBI double from Aaron Halstead.
Halstead came in on Derik Chestnut's single and an error by Kincaid, and Riverside took the lead for good.
"He was a freshman when I took over and I think a lot of people may have passed on him," Hawkins said of Green. "But if there's any kid in this program that's worked hard and deserved a moment like that it's Cameron Green. He's by far the most coachable kid I've ever met - he's a coach's dream. He understands that when you tell him something you're not downing his abilities, you're trying to make his abilities better."
Green took a more modest approach after the game.
"My coach had a lot of confidence in me. I just had to stay confident in myself and tried to hit the ball," Green said. "It's all about playing for the team. We're focused, we're going for the ring."
Before it gets close to that goal, however, Hawkins admitted that the Warriors have some growing to do.
Capital has some maturing to do as well, and Massey said growing pains are to be expected with a roster so youthful.
"We're very young," Massey said. "You can say whatever you want, but the kid standing up there at the plate with the last at-bat probably doesn't have arm-pit hair. He's 14 years old."
Brady Wilkinson (2-1) got the win for Riverside after throwing 62/3 innings and giving up just four Capital hits while striking out five. He was hurt by three Warriors errors.
Halstead and Chaz Davis each had two hits while Drew Mack went 3 for 4 to lead Riverside's offense. Each had an RBI and Halstead and Mack both doubled.
Justin Palmer had two hits for the Cougars.
