Joe Saunders had respectable numbers, giving up five hits in six innings. The problem for the Arizona left-hander was that two of those hits were homers, spoiling an otherwise good night at the ballpark. All-Star Matt Kemp homered and drove in four runs, and Juan Rivera added a solo shot off Saunders in the Diamondbacks' 6-4 loss to the Los Angeles Dodgers on Friday night.
