There's no better way to bust out of an offensive slump than to launch baseballs out of the ballpark.

That's what the Cubs did Saturday night, making sure every fan in Philadelphia went home with a souvenir.

After allowing a pair of first-inning runs, the Cubs scored a season-high 17 runs — all unanswered — and smacked six homers en route to a victory over the Phillies.

Anthony Rizzo had gone eight straight games without a homer, and decided to make up for that by going deep twice. It was also the second time this month he's registered five RBIs in a game.

Tommy La Stella recorded his first career multi-homer game, Kris Bryant slugged his 24th of the season and Ben Zobrist added to the party with a two-run homer of his own in a pinch-hit role.

Even Kyle Hendricks contributed on offense, going 2-for-4 with two RBIs and picking up his first win since May 24.

It was a complete effort for the Cubs, who look to take the rubber match Sunday at 12:35 p.m. on CSN.
