A native of Park Ridge, IL, Lucas John Gregerson was selected in the 28th round of the 2006 amateur draft by St. Louis.

The Redbirds dealt the RHP to San Diego for the 2009 season, where he made his major league debut and pitched for five years out of the bullpen. The Padres traded him to the A's, where he pitched for the 2014 season.

In December 2014, Houston GM Jeff Luhnow signed Luke to a three-year free agent deal. As of 2015, he is the Astros' closer.
