September 26, 1965 – The Minnesota Twins beat the Washington Senators 2-1 at D.C. Stadium and clinch their first American League pennant with their 99th victory of the season. It is a bit ironic that the Twins win the pennant in Washington since they themselves were the Washington Senators before moving to Minnesota after the 1960 season.
Twins pitcher Jim Kaat pitched a complete game and struck out 10 while allowing one run (0 earned) on eight hits to earn his 17th win of the season. The Twins scored their two runs on a passed ball and a Sac fly. Senators pitcher Pete Richert also pitched a complete game allowing only three hits but end up the hard luck loser for the Gil Hodges managed Senators. Box score.
