Taunting Phillies fans reaction to Braves' game-winning grand slam is priceless (VIDEO)

The Philadelphia Phillies were on the verge celebrating a win against Atlanta on Monday night when one group of Phillies fans got a serious lesson in humility after the Braves won with what turned out to be a game winning, ninth-inning grand slam.

The Phillies were up by one in the ninth inning at Citizens Bank Park when Braves slugger Dan Uggla came up to bat.

The loud-mouthed Phillies fans did what they do best and taunted Uggla — who had already hit one home run that game. 

But that festive mood in the stands changed after Uggla drove a pitch from Jake Diekman deep into the seats in left field for the grand salami.

The slow-mo replay video of the Phillies fans clearly shows them go from unbridled glee to soul-sucking depression with one swing of the bat.

And fans from Flushing to South Beach rejoiced.

Dan Uggla makes backwards throw and still gets out (GIF)

One 2013's funnier plays happened during the Braves-Nationals game Tuesday night when Dan Uggla actually threw the ball backwards on fielder's choice to first, but the team still got the out at home.

Confused? Here's the breakdown:

Uggla whiffs on the throw, then picks up the ball. His relay throw to Freddie Freeman led to Denard Span being thrown out at home on a 3-6-4-3-2 double play. Or 3-6-4-4-3-2 —depending how you look at it.

Washington still won 4-0, though, and swept the doubleheader. They've now won 27 of their last 37.
