The Padres tabbed Luebke as their first-round pick of the 2007 MLB Draft. He pitched across three levels of the minors to close out his draft year and made his big league debut as a September callup in 2010.
He made four appearances – including three starts – posting a 4.08 ERA and struck out nearly a batter per inning. In 2011, Luebke was utilized as a swingman making 46 appearances and 17 starts, logging a 3.29 ERA allowing just a .183 average as a reliever.
The following year, he transitioned back to the rotation, but after five starts needing Tommy John surgery. He would require a second surgery in 2014 and has been signed to minor league deals with the Pirates, Marlins, and White Sox since then.
