Sports Who is that young guy on the mound tonight? Written by David Schlottman on October 25th, 2008July 27th, 2014. Leave a comment So Jamie Moyer, pitcher for the Phillies, is a young 46 years old. That is one year younger than this writer. I am pulling for the Rays, but I can’t help rooting for the ‘young’ guy on the mound for the Phillies.
