1943 - Baseball Commissioner Ford Frick demonstrates the revised balata ball to reporters by bouncing it on his office carpet. This ball will prove to be fifty percent livelier than the 1942 model. When introduced in games on May 9, there are six home runs hit in four doubleheaders compared with nine home runs hit with the previous ball in the first 72 games.
1946 - Washington's Cecil Travis gets six straight hits before being stopped by Cleveland's Steve Gromek. A prewar hitting star, Travis has few other starring moments as a player after suffering frozen feet during combat in Europe.
1966 - Willie Mays hits a NL record 512th HR, topping the mark of another Giant, Mel Ott, as the Giants beat the Dodgers 6-1.
1975 - The Giants beat the Astros 8-6 in the first game of a doubleheader at Candlestick Park. In the second inning, Houston's Bob Watson scores what is calculated as major league baseball's millionth run of all time. Philadelphia National Wes Fisler scored the first run on April 22, 1876.
1980 - White Sox first baseman Mike Squires catches the final inning of an 11-1 loss to the Brewers, becoming the first left-hander to catch in the majors since Dale Long in 1958.
1981 - Yankees reliever Ron Davis strikes out the last eight batters of a 4-2 win over the Angels, tying Nolan Ryan's A.L. record for consecutive strikeouts and setting a new record for consecutive strikeouts by a reliever.
1982 - Twins rookie outfielder Jim Eisenreich, who suffers from the nervous disorder Tourette's Syndrome, is forced to remove himself from a 5-3 loss to the Red Sox when he is taunted mercilessly by bleacher fans and his violent twitching becomes uncontrollable. Eisenreich, hitting .310 after making the jump from Class A ball to the major leagues, will be hospitalized on May 9 and will make several unsuccessful comeback attempts before retiring in 1984. He will return to the majors with the Royals in 1987 after finding an effective treatment for the condition.
1996 - The Rangers have a pair of one-hit wonders. Roger Pavlik one-hits the Tigers to make the Rangers the first A.L. team to pitch back-to-back one-hitters since the Washington Senators in 1917. Neither Pavlik nor his predecessor, Ken Hill, issues a walk in the one-hitters.
1997 - Detroit pitcher Willie Blair suffers a broken jaw when he is struck by a line drive off the bat of Julio Franco. The 31-year-old Blair will bounce back and double his previous career best with 16 wins.
