The right-hander reportedly informed the Dodgers of his plans to return back in October after the NLDS, but it wasn't official until today. The option could have been worth between $8.5 million and $10 million, based on appearances in 2014.
Wilson signed a one-year, $10 million contract for 2014, and was 2-4 with a 4.66 ERA in 61 games, with 54 strikeouts and 29 walks in 48⅓ innings in his first full season since 2011.
The Dodgers also had Dan Haren exercise his $10 million player option on Thursday, and then the team declined the $14 million club option for Chad Billingsley on Friday, instead paying the right-hander a $3 million buyout.
With Wilson, the Dodgers have $189.5 million committed to 15 players in 2014.
