But the low offensive output isn't just from the Mariners series. Since returning from an eight-day road trip where the team scored fewer than six runs twice, the Padres have scored four runs in four games.
With such decreased numbers since returning to PETCO Park, questions about the park's mental effect on the players sprouted back up.
"No," Padres manager Bud Black said when asked if the park was psyching anyone out. "If it is, it shouldn't. I wish I could put a finger on it. You know, I can't."
While that may be the case, the Padres' numbers are much different at home. The teams' batting average is almost 50 points higher on the road (.252) than it is at home (.203), and the Padres have batted in 56 runs in 25 home contests to 99 runs in 21 games on the road.
However, 54 of those runs on the road came during the Padres' recent eight-game road trip to Milwaukee, Colorado and Arizona. During the road trip, San Diego hit .323 (86-for-263) with an on-base percentage of .357.
"I don't know," third baseman Chase Headley said. "I think a lot of it is the confidence when you get on the road, sometimes when you get a few hits stacked together, you score some runs, it kind of snowballs. That's the only thing that I can really say."
Padres left fielder Ryan Ludwick said the discrepancy in the numbers will be there.
"Well, I think this ballpark is definitely notorious for being a little bit different than some other ballparks around the league," he said. "The splits are going to be a little bit different."
But Ludwick said they shouldn't be that different. He said he expects the numbers to even out as time progresses. Ludwick's have already.
"I do feel much more comfortable in the box now than I have," Ludwick said. "When I got over here, I was so intimidated by right-center [field] that I felt like I had to swing harder, and it's getting to the point now where I'm going to the plate and not worrying about it. It's the same game, it's just a different ballpark. See ball, hit ball.
"But I am a fly-ball hitter, I've been a fly-ball hitter my whole career so I've hit a lot of balls to the warning track here that might have been bombs other places, but you can't worry about it."
