After the 1963 season, Houk was promoted to general manager and Yogi Berra replaced him as field manager. Early on, the team slumped under Berra, especially Boyer, who batted .218 on the season. As Berra's managing improved, the team improved with it and won its fifth straight pennant by one game over the Chicago White Sox and two over the third place Baltimore Orioles. The Yankees faced the St. Louis Cardinals in the World Series with Clete playing against his brother Ken. The Yankees lost in seven games, but not before Ken and Clete became the first brothers to hit home runs on opposing teams in a World Series game. In the 7th inning of that seventh game, Ken homered off Yankee pitcher Steve Hamilton and exchanged nods with Clete. Clete returned the favor in the 9th after homering off Cardinal ace Bob Gibson.
