In his major league debut, Luis Castro plays second base for Connie Mack's Philadelphia's A's in an 8-1 victory over the Orioles at Oriole Park. The 25 year-old Medellin native is the first and last player from Colombia to appear in the big leagues until Orlando Ramírez breaks in with the Angels in 1974.
At Colt Stadium, Ken Johnson becomes the first pitcher to lose a nine inning no-hitter when the Reds beat the Colt .45's, 1-0. Pete Rose, who attempting to bunt reaches second on a throwing error by the pitcher, scores the game's lone run in the top of the ninth inning when Nellie Fox boots Vada Pinson's two-out ground ball to second base.
Trailing by four runs at Candlestick Park, the Astros score ten times in the ninth inning to beat the Giants, 13-7. The final frame fireworks are fueled by seven hits, two walks, a passed ball, and an error.
