The Leventhal-Sidman Jewish Community Center in Newton will hold a baseball clinic on five successive Sundays, beginning February 28, for children ages 6-12.  Coaches from the Rich Gedman Baseball program will focus on developing hitting, fielding, throwing, catching and base running skills.  The clinic runs from 5-7pm each night.  Cost per clinic is $65 per session or $295 for all five sessions.  Register online at www.jccgb.org/gedman or contact 617-558-6456 or sports@jccgb.org.  The JCC is open to the entire community.
