The club has not made an official announcement, but one is expected as early as Friday.
Wells, who was 5-8 with a 5.54 ERA before being released by the San Diego Padres on Aug. 9, is expected to join the team this weekend and pitch Sunday against the Mets in place of struggling right-hander Brett Tomko. The Dodgers will pay him a pro-rated portion of the Major League minimum salary while the Padres pick up the rest of his $3 million salary.
Wells, who has posted a 4.12 ERA in his 21-year Major League career, is expected to be a solution for the Dodgers' depleted pitching staff. Currently, the Dodgers are without the services of starting pitchers Jason Schmidt (rotator cuff), Randy Wolf (shoulder bursitis) and Hong-Chih Kuo (elbow irritation).
The 44-year-old Wells struggled in his last four outings with the Padres, allowing at least five earned runs in each game, including seven runs against the Cardinals on Aug. 6.
Wells, a 235-game winner, will give the Dodgers a veteran presence in the rotation as they make a run at the playoffs.
