Alex Wood pitched three hits in seven innings to start his season 10-0 and the Los Angeles Dodgers, the NL leaders, beat the Arizona Diamondbacks 1-0 on Wednesday.
Wood became the first Dodgers starter to make a 10-0 record since Don Newcombe in 1955 when the Brooklyn Dodgers won the first of six franchise titles in the World Series.

Chris Taylor scored from first baseman in the second inning thanks to a double tug from Yasmani Grandal to center.
