2012: The Charlotte Bobcats lose their 23rd consecutive game, a 104-83 defeat to the New York Knicks, and finish the lockout-shortened 2011-12 NBA season with a record of 7-59, the lowest winning percentage (.106) in league history.
2008: During a game against the Colorado Rockies at Dodgers Stadium in Los Angeles, Dodger pitcher Brad Penny throws a 96 mph fastball that entirely eludes catcher Russell Martin and strikes umpire Kerwin Danley in the mask near his jaw. Danley loses consciousness, falls over backwards, and is subsequently removed from the field on a stretcher. He goes on to miss several weeks worth of games due to persistent headaches. On April 21, 2009, is again injured behind the plate when the barrel of Hank Blalock’s broken bat strikes him in the head during a game between the Texas Rangers and Toronto Blue Jays.
1986: The world’s worst nuclear accident to date takes place at Chernobyl in the former Soviet Union.
1962: The New York Mets acquire catcher Harry Chiti from the Cleveland Indians for cash and a player to be named later. After Chiti bats a mere .195 in 15 games, the Mets send him back to Cleveland, in effect making Chiti the first major league baseball player to be traded for himself.
