A tall lefty with a great fastball from Cleveland, Tennessee, just outside Chattanooga, Zajac makes his Pump Jacks debut this summer.
Zajac was drafted in the 28th round of the 2011 Major League Baseball First Year Player Draft by the Pittsburgh Pirates, but chose instead to attend the University of Tennessee. As the 7th-ranked prospect in the state of Tennessee last year, he was projected by Perfect Game to be selected even higher, but he slipped in the draft because of his strong college commitment. Both Perfect Game and Rawlings named Zajac to the 2011 pre-season all-Southeast Region team before injuries affected his senior season. Still, he went 3-2 with three saves with an ERA a shade over 1.00, earning all-region honors. Zajac struck out 63 in only 39.1 innings, including 16 whiffs in a single start last March. A two-way star at Walker Valley High School in Cleveland, Tenn., he pitched only 14 innings as a junior while batting .372 for the Mustangs.
