Juan Rivera homered on his first pitch as a Dodger, Matt Kemp threw out a runner at the plate, hit his 23rd homer and drove in four runs, and Clayton Kershaw allowed no earned runs over seven innings.Yet thanks to a Juan Uribe error that paved the way for four unearned runs off Kershaw in the bottom of the seventh (including a three-run homer to deep center by Xavier Nady), the Dodgers had to sweat out a 6-4 victory.The error effectively cost the Dodgers their fourth shutout in their past five games.Hong-Chih Kuo started the ninth and was in position to become the eighth Dodger to get a save this year, but the final out ended up going to Javy Guerra (with the tying run on first base) on a called strike three. By the way, the Dodger team record is 11 pitchers with a save in a single season,
