The Minnesota Twins and the Oakland A’s were tied 3-3 after nine innings of play at the Oakland Coliseum.
Ted Uhlaender singled to center field off of A’s reliever Paul Lindblad to start the inning.
Rod Carew followed with a single to right.
Harmon Killebrew sent a shot over the left field wall to put the Twins ahead 6-3, but they weren’t finished yet.
The Twins would score 8 more runs in the inning, for a total of 11. If that is not incredible enough, here are some numbers from that inning:
1 home run
3 Oakland errors
7 earned runs
16 Twins plate appearances
3 Oakland pitchers
The inning mercifully ended when Leo Cardenas hit a line drive to the pitcher, who caught Frank Quilici off of first for the double play.
The 11 runs were a record for most runs scored in an extra inning. The combined 12 runs in the 10th inning was also a record.
Here is the full boxscore.
