Breaking down UNC pitcher Patrick Johnson Posted Jul 28, 2009 Chatham's starter was Patrick Johnson from UNC, who is really just held back by his size. Johnson is 5'10" 170 and he throws with big effort. Johnson's fastball sits in the 87-89 mph range and he will occasionally touch 90. His best pitch is a hard 78-82 mph slider with tight break that he can throw for a strike. The problem with Johnson is he is pretty much showing you all that he will be, and that is not going to be good enough against professional hitters. (Cape Cod Baseball League)
