Q: Question: When was Kauffman Stadium built? Passage:At Kauffman Stadium, Dennis Leonard pitched a four-hit complete game to give the Royals a 2–1 series lead. After a one-out walk and single, Freddie Patek's RBI single off of Mike Torrez in the second put the Royas up 1–0. Next inning, Al Cowens's groundout with runners on second and third and no outs made it 2–0 Royals. The Yankees got on the board in the fifth when Graig Nettles singled with two outs and scored on Lou Pinella's double, but the Royals got that run back in the bottom of the inning when Hal McRae hit a leadoff double, moved to third on a groundout, and scored on Cowens's groundout. Next inning, Torrez allowed a leadoff walk and single, then got two outs before being relieved by Sparky Lyle, who allowed a two-run double to Amos Otis. Next inning, George Brett hit a leadoff single and scored on John Mayberry's RBI double. The Yankees got a run in the ninth when Roy White doubled with one out and scored on first baseman Mayberry's error on Reggie Jackson's ground ball before Chris Chambliss grounded out to end the game.
