It's not Kris Bryant's style to watch his home runs — even when he's launching a rocket nearly 500 feet off a gigantic video board.

Bryant hit the massive homer and tied the club rookie RBI record in the Chicago Cub's 6-4 win over Arizona.

"I knew I hit it good," he said. "No reason to watch."

Why not?

"It's just never been part of my game," he said. "I don't believe in showing up your opponent."

The homer, his 23rd of the season, also gave Bryant 86 RBI, tying a club rookie mark first set by Hall of Famer Billy Williams (1961) and tied by Geovany Soto (2008). It came off Diamondbacks starter Rubby De La Rosa and tied the score at 1-1 in the fifth inning.
