The Diamondbacks are off to the best start in franchise history thanks to Chris Young's two-run homer in the 11th inning, which lifted Arizona to a 4-2 victory over the San Diego Padres.

Micah Owings (0-1) glanced Gerardo Parra's jersey to open the away 11th, and his next pitch -- a hanging slider -- was lined into the left-field seats by Young.

The blast helped give the Diamondbacks a 4-0 record for the first time in their 15-year existence.

Arizona's bullpen blew the win for Trevor Cahill, but silenced the Padres in the later frames. David Hernandez struck out Cameron Maybin with a runner on third to end the ninth, Craig Breslow (1-0) hurled a perfect 10th to earn the win and J.J. Putz worked around a leadoff single in the 11th to earn his third save.

San Diego lost the opener of this three-game series after salvaging the finale of a four-game series against the Dodgers on Sunday.
