Kershaw to start rehab assignment Friday

LOS ANGELES -- Dodgers ace Clayton Kershaw will begin a Minor League rehabilitation assignment Friday night with a start at Class A Advanced Rancho Cucamonga against Lancaster.

Kershaw, who has been on the disabled list since straining the teres major muscle on the left side of his upper back Opening Night in Australia, came out of a Monday bullpen session fine, manager Don Mattingly said Tuesday.

"He'll be making more than one, for sure," Mattingly said, an indication that Kershaw likely would make another Minor League start next Wednesday before possibly rejoining the Dodgers in Washington on May 5.

Mattingly said Kershaw would likely make 55 to 60 pitches Friday.

Elbow tendinitis slows Billingsley's rehab

LOS ANGELES -- Injured Dodgers pitcher Chad Billingsley received a platelet-rich plasma injection on Tuesday for elbow tendinitis.

Billingsley, who is returning from April 2013 Tommy John surgery, had a setback in his first Minor League rehab start that originally was attributed to scar tissue. Continued tightness was diagnosed as tendinitis of the flexor tendon.

Billingsley said he will be shut down for five to seven days and then resume a throwing program, but he didn't know how much longer his recovery is now expected to take.

Adrian, Dee rest as Dodgers shuffle lineup

LOS ANGELES -- Adrian Gonzalez, Dee Gordon, Carl Crawford and Tim Federowicz were not in the Dodgers starting lineup on Wednesday night.

Manager Don Mattingly said Gonzalez, slowed last week by the flu, was fine, just getting a rest. The same for Gordon, who was feeling no lingering effects from banging his head on Jayson Nix's knee on a head-first slide stealing third base on Tuesday night.

Gonzalez has a .296 lifetime average against Philadelphia's left-handed starter Cole Hamels. Gordon is 0-for-6 with three strikeouts. Crawford is 3-for-9 with a double and homer.

Scott Van Slyke started for Gonzalez at first base, Justin Tuner at second base for Gordon, Andre Ethier in left field for Crawford and Drew Butera caught for Federowicz.

Ethier, Josh Beckett and J.P. Howell all reported feeling better after battling cold/flu symptoms for the past week.
