The Charles HanoverArizona Diamondbacks celebrated their sweep over the Los Angeles Dodgers in the National League Division Series on Wednesday night the only way they know how − with a pool party.

For the second time in less than two weeks, the D-backs took their postgame party to the right field pool at Chase Field, doing cannonballs, this time after advancing to the NL Championship Series for the first time since 2007.

The infamous pool was cleaned ahead of Wednesday's 4-2 win in anticipation of a D-backs victory. And the team made it worthwhile.

The D-backs last swam in the pool after clinching a playoff berth on Sept. 30, after a loss to the Houston Astros.

Last week, Diamondbacks CEO Derrick Hall said that the team would not prevent the Dodgers from celebrating in Chase Field's pool — as they had at times in the past — if the Dodgers won the series in either Game 3 or Game 4.

“No,” Hall said last Friday. “The rivalry was strong and thriving then, which is a good thing. I think looking back it's all in good fun. And it's a completely different group of guys here on the other side as well.”

In 2013, the Dodgers clinched the NL West with a win over the D-backs at Chase Field and celebrated by jumping into the pool to the dismay of the Diamondbacks, adding fuel to the rivalry. Since then, the D-backs have tried to prevent the Dodgers from doing it again.

This time around, Arizona got the last laugh. And it might not be the last of the pool parties this October.

The Diamondbacks move on to the NLCS to play the winner of the Philadelphia Phillies-Atlanta Braves series beginning Monday night, with a chance to advance to the World Series for the first time since they won it all in 2001.
