LOS ANGELES – The Dodgers could use some wins after a rough two-game series in Detroit and with the looming All-Star break lulling them into some bad habits lately. Carl Crawford is back, possibly tonight, but apparently with nowhere to play.There are plenty of story lines, but the start of this four-game series with the San Diego Padres is really all about one thing: Clayton Kershaw's scoreless streak. He is 23 innings short of Orel Hershier's major league-record streak of 59 consecutive scoreless innings and he is facing a lineup that has been shut out 11 times already this season.
