Dodgers reach to minors for catching help

It has been a different kind of season for Tim Federowicz, who seemed to cement himself in the backup catcher role last season but has already been optioned to Triple-A twice this season. The Dodgers sent him down again Wednesday in favor of veteran catcher Miguel Olivo, who was hitting .390 with four home runs and 18 RBIs for Triple-A Albuquerque.

Federowicz, who has been doing a lot of the catching with A.J. Ellis working his way back from knee surgery, has no one to blame but himself. He was batting .109 in 50 plate appearances.

Olivo, 35, was on a minor-league deal, so the Dodgers had to make room on their 40-man roster to get him to the major leagues. They transferred Chad Billingsley to the 60-day disabled list, another indication that his rebound from Tommy John surgery hasn’t gone as well as it appeared it might in spring training.

Billingsley received an injection of platelet-rich plasma in his right elbow last week and is hoping to resume his throwing program this week. He felt discomfort in his elbow during a throwing session in San Francisco. MRI results showed tendinitis.

Olivo, a 10-year veteran, hasn’t played in a major-league game since June 12, 2013. He reportedly walked out on the Miami Marlins two days after that, upset about a lack of playing time. The Marlins responded by placing him on the restricted list, where he was not paid and could not sign with another team.
