Justin Upton hit one of the longest home runs ever seen at Atlanta's spring training complex, a towering drive that cleared the grass berm beyond left field, as the Braves defeated the Miami Marlins 7-6 Monday.

Upton's teammates estimated the homer went at least 450 feet. It was his first hit of spring since joining the Braves in a blockbuster trade with Arizona.

The Marlins led 1-0 when Jason Heyward opened the fourth with a drive over the right-field wall. Upton made it back-to-back homers off loser Scott Maine, and brother B.J. Upton chipped in with a double, coming around to score on a stolen base and wild pitch.

Atlanta extended the lead to 7-1 before Miami put together a five-run eighth. Anthony Varvaro worked the ninth for a save.
