Last night, we headed back to Nonantum Boxing Club in Newton to catch up with John Sementelli. John, who is "Shirtless" Ray McCarthy's cousin, was getting some mitt work in with Marc.   John is one of the nicest guys amongst this years group of fighters, but when he puts those gloves on, you better be ready! John was feeling a little skinny after losing five pounds due to buying his first home (congrats again!), but something tells us he'll be fine! Don't wait to buy tickets to see John fight on May 17th at House of Blues for Haymakers for Hope Rock n' Rumble!
