Contreras went 2-for-4 with two solo home runs in Friday's 6-3 win over the Rangers.
The blasts provided insurance runs in the victory, as Contreras took Brock Burke deep in the fourth inning and connected off Albert Abreu in the sixth. They were the first two hits of the season for Contreras, in his second game with Atlanta this season, but regardless of how he does, the 24-year-old may have to head back to Triple-A Gwinnett for more development once Manny Pina (wrist) gets healthy.
