Light-hitting Jedd Gyorko drove a two-run homer an estimated 438 feet and Justin Upton and Derek Norris also hit two-run shots for the San Diego Padres, who beat the Colorado Rockies 8-6 Sunday for a three-game sweep.

Colorado’s Nolan Arenado and Charlie Blackmon each homered twice.

Gyorko, whose .145 average has basically relegated him to a platoon situation at second base, connected with pinch-hitting in the pitcher’s spot in the sixth inning. It was his first of the year and gave him five RBIs.

Gyorko has struggled since signing a $35 million contract early in the 2014 season, which was just his second in the big leagues.

Upton homered, hit two doubles and drove in three runs for the Padres, who rebounded after being swept by Houston and losing two of three to the Dodgers.

Spacious Petco Park played like a bandbox during the nine-game homestand, with the Dodgers, Astros and Rockies combining for 20 homers while the Padres hit 10.
