LOS ANGELES -- The book closed Saturday on another stellar regular season for Los Angeles Dodgers right-hander Zack Greinke.He was the tough-luck loser in a 1-0 defeat at the hands of the visiting Colorado Rockies, but Greinke still finished with a 15-4 record and 2.63 ERA for the NL West champions.What lies ahead is his second career trip into the postseason. Greinke said he's satisfied with how he's pitching."It could be worse, that's for sure," he said.
