The baseball world learned Will Klein's name following his massive pitching performance for the Dodgers in Game 3 of the World Series on Monday ... but there's at least one guy who wasn't surprised one bit -- his college coach!!
We chopped it up with Jack Anderson -- the manager of the Eastern Illinois Panthers -- after his former player helped lift L.A. to a 2-1 lead over Toronto.
Anderson, who the New York Yankees selected in the 2000 MLB Draft, said he initially fell asleep during the 12th inning ... but was jolted awake by his son when he noticed Klein on the mound.
