LOS ANGELES -- As Chad Billingsley works his way back from Tommy John surgery, he has started to ponder why so many fellow pitchers have joined the club he never wanted to be part of.The Miami Marlins' Jose Fernandez is the latest bright, young pitcher who might be headed for the season-ending surgery pioneered by longtime Dodgers team physician Frank Jobe. Billingsley had his surgery 13 months ago and threw his second bullpen session before Tuesday night's game, mixing fastballs and changeups.
