On June 7, 1961, Stan Musial went 4 for 4 with two singles and two home runs in an 8-6 win over the Cubs. After the Birds put up two runs in the first then two more in the second Stan decided to jump into the mix in the third with a two run shot. Musial's second jack came right after the Cubs had scored two runs in the top of the 7th, The Man erased their momentum by parking his second two run shot over the wall in right field. Chicago made it a game with home runs by George Altman and Ernie Banks in the eighth and ninth but it wouldn't be enough and the Redbirds fans went home happy.
