Clayton Kershaw and the offense got the Dodgers to the seventh inning with a lead. Then it was nervous time without Kenley Jansen in the bullpen. But unlike last month's collapse when Jansen was sidelined by an irregular heartbeat, on Friday night Kershaw's six solid innings were followed by five relievers for the final nine outs in the Dodgers' 4-2 win over the Rockies, whose lead over Los Angeles in the National League West was trimmed to one-half game.
