VIDEO: Schwarber hammers HR on top of scoreboard

The home runs were flying out of Wrigley Field.

After the Chicago Cubs belted a playoff-record six home runs during Monday's win, Joe Maddon's crew were back at it again in Game 4.

The 22-year-old rookie took St. Louis Cardinals reliever Kevin Siegrist's 93-mph offering deep, sending a 419-foot moonshot on top of the videoboard in right field to give the Cubs a 6-4 lead.

The home run was the third of the postseason for Schwarber, who told reporters after the game he predicted he'd hit the blast to teammate Dexter Fowler during the previous inning.

"We were out in center field and Joe was making a pitching change, and I was just joking around, I said, 'I'm going to hit a home run off this guy,' and he's like 'Well, do it,'" Schwarber recalled after the game. "There you go."

The Cubs hung on for the 6-4 win, advancing to the NLCS for the first time since 2003.
