Justin Upton is looking to prove doubters wrong and his swing is improving.
"It looks like Justin Upton is on a mission," a scout said.
Since March 16, he's 7-for-14, with three home runs, nine RBIs and seven runs scored.
Upton hit a home run on Friday that might have been the longest home run ever launched at Champion Stadium in Disney. It went close to 400 feet.
Braves hitting coach Greg Walker says Upton just went "back to the way he used to swing."
