LOS ANGELES -- The Los Angeles Dodgers kept their lead in the NL West intact and might have figured out a new bridge to closer Kenley Jansen along the way.Young reliever Pedro Baez got four key outs in the seventh and eighth innings of the Dodgers' 2-1 win over the Arizona Diamondbacks on Friday night. Jansen, who blew a two-run lead during a four-out save chance Wednesday, handled the ninth inning exclusively this time and breezed to nail down his 40th save.
