Antti Niemi [[ nee-YEM-ee ]] turned aside all 34 shots he faced as the Sharks shutout the Blackhawks, 1-0.  Niemi, who backstopped the Blackhawks to a Stanley Cup title in 2010, notched the 14th shutout of his career.  Jason Demers scored the only goal of the game for San Jose, which has won four in-a-row.  Corey Crawford made 20 saves in net for Chicago, which has lost three straight.  Chicago plays at Anaheim tomorrow night and wraps up a six-game road swing on Saturday at Los Angeles.
