Bruce D. Drummond
The photo shows him in the uniform of the University of Connecticut.
An article in the White Plains (NY) Journal-News of June 25, 1969 ties together the Bruce Drummond who signed with the Seattle Pilots to the Bruce Drummond who pitched for UConn, so this is the right guy. The article also says that he was a star at Clarkstown HS. That HS (now divided into Clarkstown North and South) is in the White Plains area.
