Watch: Anthony Rizzo Has The Most Joyous Reaction You'll Ever See After Jake Arrieta's Homer

(CBS) Jake Arrieta on Monday night continued the torrid hitting by Cubs pitchers in their National League Divisional Series, hitting a three-run homer off Giants ace Madison Bumgarner in the second inning to give Chicago an early 3-0 lead. Of the Cubs' nine RBIs in the series, six have now come from pitchers.

Perhaps no one was more excited by Arrieta's homer than first baseman Anthony Rizzo, who was absolutely ecstatic in the Cubs dugout after the ball cleared the wall. Check out Rizzo's reaction below.

It's pure, unbridled joy.
