Leading by two runs in the bottom of the ninth inning, the Orioles escape a no-out, bases-loaded jam when John Wathan hits into a run-scoring triple play to end the game, giving the team a 7-6 victory over Kansas City at Royals Stadium. The Kansas City pinch-hitter’s sac fly to right field (1) is deep enough to score Al Cowens from third base, but Freddie Patek, the runner on first, is caught in a run-down on the throw (2) and Dave Nelson, stranded off third base, is tagged out (3) by Mark Belanger, completing the 9-6-4-6 triple killing.
