Orioles right-hander Kevin Gausman is scheduled to face Tampa Bay left-hander Drew Smyly, and first pitch is set for 7:05 p.m.
How does this year's squad stack up through 130 games against successful Orioles teams of the past? With a 75-55 record, the Orioles are seven games ahead of the New York Yankees (68-62) in the American League East division. Their magic number to clinch is 26.
Here's how the Orioles fared in previous seasons when they made the playoffs.
Chico Salmon's bunt single with two outs in the bottom of the 11th inning gave the Orioles a walk-off win over the Seattle Pilots on Aug. 28, 1969. Salmon, who had entered the game as a pinch-runner for first baseman Boog Powell in the eighth inning, drove in Curt Motton with the winning run in the 4-3 victory in front of 8,118 at Memorial Stadium as the Orioles improved to 89-41. Right-hander Jim Palmer gave up three runs and eight hits in nine innings, and right-hander Eddie Watt earned the win after pitching two scoreless innings out of the bullpen.
