PHOENIX -AP- Brandon McCarthy gave Los Angeles a much-needed strong start, Yasmani Grandal homered in a six-run fifth inning and the Dodgers avoided being swept in three games in the desert with a 6-2 victory over the Diamondbacks on Sunday.After scoring 24 runs in the first two games of the series, the Diamondbacks managed only a first-inning, two-run home run by Paul Goldschmidt. McCarthy (3-0) blanked Arizona on two hits after that. He went seven innings, allowing two runs on five hits with six strikeouts.Shelby Miller (2-2) threw four shutout innings before walking the first two batters and giving up an RBI double to Corey Seager in the fifth. He threw one more pitch and left after a visit to the mound by the Arizona trainer.There was no word on why Miller departed.The Diamondbacks lost at home for just the second time in 10 games this season.
