The Los Angeles Dodgers resume their pursuit of the top spot in the National League West with a three-game series against the Arizona Diamondbacks beginning Friday at Dodger Stadium. The Dodgers (57-45), who lost two of three to the Diamondbacks following the All-Star break, have gone 16-9 in their last 25 games and made up ground on the struggling NL West-leading San Francisco Giants. San Francisco's advantage in the division has dwindled from 6 1/2 games at the All-Star break to two.
