Buster Posey hit a tie-breaking homer as the San Francisco Giants completed a remarkable comeback victory over the Arizona Diamondbacks on the opening night of the new Major League Baseball season.
Arizona exploited a poor defensive display from the visitors to Chase Field to grab a 7-3 lead but the Giants pulled even with four runs in the seventh inning.
The deadlock remained intact until the ninth, when Brandon Belt singled and Posey made it 9-8 for the win by driving a pitch deep into the left-field stands.
