Pitcher Tony Cloninger hits two grand slams and drives in nine runs, as the Atlanta Braves rout the Giants at Candlestick Park, 17 – 3. Cloninger is the first National League player to slam two in a game, and the first pitcher ever, and his nine RBIs are a major-league record for pitchers, breaking Vic Raschi’s mark of 7.

The National League record for pitchers was 5, held by several; the last hurler to collect five RBIs in a game was Cloninger himself, who had five on June 16th against the Mets.

The first Slam came in the first inning, with only 2 outs Collinger was the 9th man to hit in the inning and he took Bob Priddy,  Deep and gave the Braves a 7-0 Lead.

Collinger would face Ray Sadeck 3 innings later, again with the bases loaded and two men out, Collinger homered again giving the Braves a 13-0 lead.

Ray Sadeck would later homer himself of Collinger in 5th, but the fireworks were not over as Collinger would again face Sadeck in the top of the 8th and drive in the 16 run of the game for the braves with a 2 out single. Collinger in good form also pitched a complete game for the Braves.
