The Mets are hoping to leave their three-game set against the Atlanta Braves with at least one win.
Wrapping up the series on Thursday, Pete Alonso put the Mets in a great position to do so before the Braves even recorded an out.
In the top of the first at SunTrust Park, Alonso sent a pitch from Julio Teheran over the outfield wall in dead center field, 451 feet away from home plate.
The ball got soaked too, landing in the fountain just beyond the wall.
On the homer, Amed Rosario who doubled to start the game and Joe Panik who singled, scored for the Mets.
Alonso's home run also helped him tie the National League's record for most home runs in a single season by a rookie (Cody Bellinger -2017) and he's only two behind the Mets' overall single-season home run record of 41 held by Carlos Beltran (2006) and Todd Hundley (1996).
