Players attempting to play in MLB often choose not to defect to the United States, because establishing residency in the United States means they must enter the MLB Draft . If they defect to another nation, they can become free agents , allowing them to choose their offer.  The largest contract given to a Cuban defector is outfielder Rusney Castillo 's seven-year contract with the Boston Red Sox , signed in 2014, worth $ million.  First baseman José Dariel Abreu signed a six-year contract worth $68 million with the Chicago White Sox in 2013.  The largest contract given to a pitcher was the $32 million the New York Yankees gave to José Contreras in 2002,  while the Cincinnati Reds signed Aroldis Chapman for $ million in 2010. 
The Mitchell Report also stated that interviews were requested of five MLB players who had spoken out publicly on the steroid issue. Of these players, only one, Frank Thomas , was willing to be interviewed. The Mitchell Report stated that there was no evidence that any of these five had used performance-enhancing drugs. Curt Schilling , one of the four players who declined to interview with Mitchell, explained that he denied Mitchell's request because he "would have nothing to offer" Mitchell's investigation "other than personal opinion and hypotheticals."
