PHOENIX -- The Los Angeles Dodgers continued to do their part in keeping the Arizona Diamondbacks miserable.They beat Arizona 7-0 at Chase Field on Friday night, with Dodgers hitters putting on a power show and Zack Greinke a pitching clinic. It was the Dodgers' eighth win against Arizona in nine games this season and gave the Diamondbacks a 4-18 record at home, amazingly.How it happened: Arizona actually put pressure on Greinke early, but he got some big strikeouts and a key double play to ease his way out of it and then he got in a groove and the Diamondbacks went down meekly thereafter.
