After serving 15 months of a three-year term in a California prison, former big leaguer Lenny Dykstra is expected to be released on Sunday, according to Frank Fitzpatrick and Zach Berman of the Philadelphia Inquirer.

Dykstra, 50, pleaded no contest to three charges of grand theft auto and one count of filing a false financial report in October 2011, the Inquirer reported. He was sentenced to three years after completing a drug and alcohol rehabilitiation program.

"I was surprised they let him out before the three years, to be quite frank with you," said Christopher Frankie, who recently authored a Dykstra biography. "Because he blatantly disobeyed the court, and a lot of the stuff was very brazen. He was doing it in the full view of law enforcement."

Twenty-one additional charges against Dykstra were dropped in 2011 after he agreed to a plea of no contest to the other four charges. Dykstra then said he only agreed to the plea bargain to get out of jail so he could build his case, the New York Daily News reported in 2012. A later attempt to withdraw his no-contest please was denied by Los Angeles County Superior Court Judge Cynthia Eulfig, who gave him a sentence slightly lower than the four-year maximum requested by prosecutors, the Daily News reported in March 2012.

Dykstra, who played parts of eight years with the Phillies and five with the Mets, last played in MLB back in 1996. He's a career .285/.375/.419 (120 OPS+) hitter and a three-time All-Star.
