No not Mark Timmons, nor Mark Prior, nor Mark Fidrych, or Mark McGwire
The Mark to whom I refer is right-hander Mark Washington of the Tulsa Drillers, perhaps soon to be of the OKC Dodgers. He was born in Glen Mills, attended high school at Episcopal Academy in Merion, and attended university at Lehigh University. All three locations are in his home state of Pennsylvania.
He was selected by the Dodgers in the 25th round of the 2017 First-Year Player Draft following his junior year at Lehigh. His selection was the 760th in that draft.
