Bostick is a former 2nd round pick of the Texas Rangers from the 2013 draft. He came to the Astros in a 2015 offseason trade for catcher Carlos Corporan. Corporan hit only .176/.244/.299 in his lone season with the Rangers, who released him following the 2015 campaign.
Yet to make his major league debut, Bostick spent all of this season to date with Round Rock in the PCL. Of course, the PCL has seen a record number of home runs this season, so Bostick is hardly the only pitcher suffering from a few too many long balls.
Across 80 1/3 innings, Bostick went 4-5 with a 7.28 ERA while giving up 11 hits and 2.1 home runs per nine innings. He also saw a rise in his walk rate this season. The 24-year-old has mostly been a starter throughout his minor league career.
