Can you tell me about professional US sports games that have been fixed in the past?
<|assistant|>
There have been a number of high-profile professional sports games that have been suspected to have been fixed over the years. The most famous of these involve Major League Baseball (MLB), where teams have been found to have made agreements with gamblers and players to manipulate the outcome of games, often to the detriment of the betting public. MLB has since implemented various integrity-preserving measures, including advanced electronic monitoring systems and increased vigilance on teams' and players' activities. In addition, a number of basketball games in the early 1970s and 1980s have been suspected to have been fixed or rigged, resulting in a series of high-profile criminal trials. Finally, suspicion has been cast on several NFL games in the 1970s and 1980s due to unexpected large wins by certain teams or unusual patterns of betting.
