Gregory Silveira, the gambler who had ties to Phil Mickelson, was sentenced to a year in prison Monday.
This comes via a report by Mike Fish of ESPN.com. It was Silveira that, according to sources from ESPN's Outside the Lines, aided a "gambling client" identified as Phil Mickelson between February 2010 and February 2013. OTL originally cited Silveira's plea agreement, which included a reference to "P.M." that was later removed. Silveira pleaded guilty to three counts of money laundering last year. Mickelson was not charged and is not under investigation.
Most recently, however, Mickelson was tied to Bill Walters for insider trading, in which he has agreed to pay nearly $1 million deemed "unfairly earned" by the SEC.
Mickelson will attempt to win the career grand slam next week at the U.S. Open at Oakmont.
