On July 6, 1929, the Cardinals broke out of an 11 game losing streak in grand fashion by scoring a National League record 28 runs at the Baker Bowl in Philadelphia. The 28 runs still stands today as the National League record. It happened after the Phillies had knocked the Cards off 10-6 in the first game of the doubleheader, in the nightcap the Cardinals did more than stop a losing streak they stopped it with an exclamation point. The Cardinals scored ten runs in the first, one in the second, two in the fourth, then ten more in the fifth. With the lead 23-4 they weren't done, the Redbirds put up 5 more runs in the eighth before the Phillies tacked on two more then the bludgeoning came to an end with the Cardinals on top 28-6. Jim Bottomley and Chick Hafey both hit grand slams, Bottomley had crushed two home runs in the first game of the twin billing to give him three on the day The pitcher on the mound that day for the Cardinals was Fred Frankhouse, he not only picked up a complete game winner for the club, he picked up 4 hits and knocked in 4 baserunners in the annihilation of the Phillies. The record has not since been matched by any other National League team and is the fourth highest run total in the modern era.
