Tucker, a former standout at the University of Florida, hit .250 with 24 homers and drove in 96 runs for Triple-A Fresno last season. He hit .243 with 13 homers as a rookie with the Astros in 2015 but hit only .164 in 48 games with Houston in 2016.
Tucker could contend for playing time in left field for Atlanta after Matt Kemp was traded to the Dodgers in a five-player deal on Saturday. The trade opened a spot for top prospect Ronald Acuna, but Acuna is only 20 and has yet to make his major league debut.
Go Braves! Go Gators!
