The Pirates, stuck in a 15th consecutive losing season, don't sell out PNC Park that often. On one of the few nights they will, some fans don't plan to stick around long. With only the third capacity crowd of the season expected for a Bob Walk bobblehead doll giveaway Saturday night, some longtime rooters led by businessman Andy Chomos of Wexford, Pa., want those attending the game against Washington to walk out in protest of ownership's perceived lack of direction. Fans are being urged to wear green -- to represent ownership's lack of financial commitment to fielding a winning team -- and leave their seats after the third inning.
