The Cardinals are set to promote righty reliever Mitch Harris on Tuesday, Derrick Goold of the St. Louis Post-Dispatch tweets. When Harris makes his first pitch with the Cardinals, he’ll become the first graduate of the U.S. Naval Academy to pitch in the big leagues in nearly a century, as Yahoo! Sports’ Jeff Passan wrote last month. The Cardinals drafted the 29-year-old Harris in the 13th round all the way back in 2008, but Harris spent several years honoring his commitment to the Navy, traveling the world as a weapons officer.
