IF ONLY GEORGE COSTANZA STILL WORKED FOR THE TEAM

          The NEW YORK CONVENTION AND VISITORS BUREAU wants to
     show the hour-long series finale of NBC's "SEINFELD" on the
     jumbotron at Yankee Stadium following the Rangers-Yankees
     game on May 14, according to Richard Sandomir of the N.Y.
     TIMES.  Yankees General Counsel LONN TROST said that the
     team's marketing department "was investigating the
     feasibility of getting the rights to show the episode on
     tape."  NBC West Coast President DON OHLMEYER said that he
     "doubted the plan could succeed."  Ohlmeyer: "You'd be
     playing it in front of a paying audience in an arena. 
     That's not what the rights are for" (N.Y. TIMES, 4/2).  
          THE SPITTER RETURNS? In N.Y., Neal Travis reports that
     former Mets 1B KEITH HERNANDEZ will appear in the "Seinfeld"
     finale.  Hernandez previously appeared in "one of the most
     watched episodes in the show's history" (N.Y. POST, 4/2).
