According to legend, Dodger hurler Elmer Stricklett introduces the spitball, helping Brooklyn beat the Giants, 4-3.

In a 10-1 loss to the Dodgers at Forbes Field, Dale Long is held hitless by Don Newcombe, ending his consecutive-game home run streak. The Pirates' first baseman had established a new major league mark by homering in the last eight Pittsburgh contests.
At Dodger Stadium, Dusty Baker, Rick Sutcliffe, Steve Garvey, Gary Thomasson, Derrel Thomas, Joe Ferguson, and Davey Lopes set a team record by hitting seven home runs as the Dodgers crush the Reds, 17-6.
