Padres' prolific offense hitting a rut in San Francisco

SAN FRANCISCO -- The most productive offense in the National League has hit the skids again at the hands of Giants' pitching.

The Padres were shut out for the second time in as many days -- and for the fourth time in 2015 -- on Tuesday, falling, 6-0, at AT&T Park, as their bats fell silent.

Going back to Sunday's victory over the Rockies, the Padres have gone 20 consecutive innings without a scoring a run. Earlier this season, they went 22 innings without a run, a stretch that included games against these same Giants.

"I think since I've been here, we've struggled up here. This is a tough place to win games," said Padres second baseman Jedd Gyorko. "They scrap and fight, and they always seem to get the big hit up here."

The Padres managed four hits against Ryan Vogelsong and two relievers on a cool night where the offense was equally chilly.

"[Vogelsong] mixed pitches, the curveball came into play, had the fastball at the top of the zone with a little run in on our hands," said Padres manager Bud Black. "Little cutter away from the righties, in to the lefties, [he] changed speeds, but pretty much textbook pitching.

"We hit the ball on the nose a number of times to no avail."

The Padres loaded the bases in the sixth inning with two outs but Derek Norris, one of the Padres' hottest hitters, got out front on a curveball, grounding out to third base to end the threat.

The Padres are just 6-21 since 2012 at AT&T Park and have dropped six of their past seven here going back to last season.

No matter how improved the Padres offense is from a year ago, Gyorko knows there are times when good pitching can simply suffocate good hitting.

"I just think you're going to go through stretches where guys are throwing well," he said.
