Giant reliever Hoyt Wilhelm homers in his first major league at-bat, a fourth-inning blast off Dick Hoover in the team's 9-5 victory over Boston at the Polo Grounds. During the next 21 years, covering a span of 1070 games and 432 official at-bats, the knuckle-balling future Hall of Fame hurler will never homer again.
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.
Joining the Giants, the Cubs become the second franchise in major league history to win 10,000 games, beating the Rockies in a ten-inning contest at Coors Field, 7-6. Chicago, which has won six in a row and is off to a 15-6 start for only the fourth time in the last century, has a 10,000-9,465 all-time won-loss record during their 122 years of existence in the Windy City.
