[Clemens, a right-handed hitter with power to all fields, has hit over .300 with Greeneville and belted several mammoth homers. His first was a grand slam and reached the football stadium over the right-field hill in Johnson City. A blast atop the clubhouse in Pulaski, Va., was estimated to have gone 515 feet. His father wasn't there for either.He was at a speaking engagement when Koby hit his grand slam and wondered why his cellphone kept vibrating. His wife, Debbie, and others were trying to let him know.] He's on his way and he hasn't done it on my coattails, ... I'm happy for him. I'm just kicking back and enjoying it.
