The Dodgers finally added Brian Wilson to their active roster Monday, 20 days after the former San Francisco Giants closer signed with the team through the remainder of the season.

Wilson threw a simulated game Friday in Philadelphia and recovered well enough to join the Dodgers’ expanded bullpen for the first of three games against the Miami Marlins. The Dodgers chose to option Scott Van Slyke to Triple-A Albuquerque rather than a relief pitcher, giving the Dodgers eight relievers and a four-man bench tonight.

Wilson’s next major-league pitch will be his first since April 12, 2012. He was subsequently shut down for the season with a torn ulnar collateral ligament in his right elbow and had season-ending Tommy John surgery.

Van Slyke, who’s had four separate stints with the Dodgers this season, is batting .252 (26-for-103) with six home runs, seven doubles and 16 RBI in 38 games. He is likely to be recalled on Sept. 1 when rosters expand.

Wilson becomes the first player to wear the 00 uniform in franchise history. Al Oliver wore 0 in the 1985 season.
