A former White Sox scouting executive pleaded guilty on Friday in an alleged kickback scheme targeting players from impoverished parts of Latin America hungry to play in the United States. David Wilder, 50, pleaded guilty to one count of mail fraud as part of a plea agreement, telling a federal judge in Chicago, "I understand what I have done." Prosecutors said he and two others were supposed to pay signing bonuses matching each player's skills but instead fraudulently inflated the amounts and took the additional money for themselves. In a statement, the White Sox said they were pleased Wilder "will face responsibility for his crimes."
