Mark Reynolds and Chris Synder homered as the Arizona Diamondbacks assured interim manager Kirk Gibson of his first non-losing series with a 5-4 victory over the Florida Marlins on Saturday.

The win gives the Diamondbacks a 2-1 advantage in the series in Gibson’s third set at the helm since taking over on July 2.

The Arizona offense got to Florida starter Nate Robertson early, building a 3-0 through four innings as Chris Young and Justin Upton plated runs and Reynolds hit his 20th homer of the season.

After Florida closed to within 3-2 on single tallies in the fifth and six innings off Ian Kennedy, Snyder hit a two-run home run to push the advantage to 5-2.

Right-hander Juan Gutierrez earned the save, his second, to give Kennedy (4-7) his first win since May 19. Chad Qualls had started the ninth but the first three batters reached to close within 5-4 on a Ronny Paulino pinch-hit, two-run single.

Kennedy gave up two earned in 5 1/3 innings. The right-hander allowed five hits and two walks with five strikeouts.

Robertson (6-7) allowed six hits, five runs and three walks.
