SAN FRANCISCO >> There is no gray area in Kenley Jansen's job."We either win or we lose when I'm out there," the Dodgers' closer said, describing the high-wire life of closing out games.Saturday night was one of those occasional nights when things did not end well. Jansen gave up four consecutive hits for the first time in his big-league career -- he has only allowed a total of four hits in a single appearance three times before -- and suffered his third blown save of the season.
