The Pirates will unveil the plan for a statue of Bill Mazeroski this weekend at PirateFest, according to multiple sources.
The statue, PNC Park's fourth, will be added during the coming season, which will represent the 50th anniversary of Mazeroski's winning home run in the 1960 World Series.
The statue has been in the works -- quietly -- for several months. Neither a design nor a location has been determined.
Mazeroski and other members of that championship team will be on hand for the PirateFest activities, including the unveiling of the design. That could happen Friday night in front of season-ticket holders.
The three current statues honor Roberto Clemente, Willie Stargell and Honus Wagner. There also is a Ralph Kiner memorial inside the stadium of just his hands gripping a bat.
