Kris Bryant wasn't looking to go deep when he came up in the second inning Saturday night.
"You know, bases loaded, not trying to do too much," Bryant said.
He wanted to keep a rally going. Instead he broke the game open with a grand slam.
Bryant hit two early homers and drove in six runs to lead the Chicago Cubs to a 7-2 victory over the Miami Marlins.
The multihomer game was the second for Bryant, who hit a two-run drive in the first inning and chased Marlins starter Jarred Cosart (1-4) with the grand slam in the second that made it 7-0.
"It was pretty much (Bryant), that was our offense," Cubs manager Joe Maddon said. "He was definitely ready in the opening part of the game."
Bryant's grand slam barely cleared the wall — but his first homer nearly left the park, landing in the top row of the bleachers in left. He became the first Cubs player to hit two grand slams in his rookie season since Hall of Famer Billy Williams in 1961.

Cosart, who gave up seven runs, four hits and three walks in just 1 2-3 innings, was making his first start after a month off to recover from vertigo. He was optioned to Triple-A New Orleans after the game.
"There's no excuses," Cosart said. "It's a performance-based industry and I didn't perform well today. I've got to get back at it and get ready for my next start."
Cubs starter Clayton Richard (1-0) sailed into the seventh inning in his first major league outing since 2013, pitching Chicago to its fourth victory in five games. Acquired from Pittsburgh in a trade Friday, he gave up two runs and eight hits with one walk in 6 1-3 innings.
