The New York Yankees, Cleveland Indians and St Louis Cardinals posted walk-off wins while the Houston Astros delivered one of the craziest come-from-behind victories of the MLB season.
In New York, the Yankees locked up a playoff spot with a 3-2 win over the Baltimore Orioles on an Aaron Hicks walk-off double in the 11th inning.
In St Louis, Tyler O'Neill did not just deliver a walk-off home run in a 5-4 win over the San Francisco Giants, but he also got the Cardinals one game closer to the top wildcard spot in the National League as the Milwaukee Brewers fell to the Pittsburgh Pirates 3-0.
