The Philadelphia Phillies, the last team to clinch a playoff spot in the regular season, are now halfway to being the last team standing.

The host Phillies became the first team to clinch a League Championship Series berth Saturday afternoon, as Brandon Marsh hit a three-run homer in the second inning to key an 8-3 win over the defending World Series champion Atlanta Braves in Game 4 of their National League Division Series.

"You've got to beat the champs to be the champs," Phillies outfielder Bryce Harper told Fox Sports 1 immediately after the game.
