Hernández was signed as a non-drafted free agent by the Atlanta Braves on September 16, 2000. He spent five seasons in the Braves' minor league organization, but only played 19 games for their AAA affiliate, the Richmond Braves, before moving to Baltimore.
Hernández was claimed off waivers by the Baltimore Orioles on October 12, 2006. He made his major league debut for the Orioles as a late-inning defensive replacement July 8, 2007 against the Texas Rangers. Luis collected his first major league hit, a double, in his second career game on July 12, 2007. The game was played at Camden Yards, against the Chicago White Sox. Hernández got his hit, a line drive to center field, off of the first pitch he saw from White Sox relief pitcher Dewon Day in the bottom of the ninth inning. He also got his first major league RBI on the play, as Jay Gibbons came in to score. His first major league home run was hit on September 27, 2007 against the Toronto Blue Jays.
