Chase Headley is ready to restart his season. He hopes it’s the last time, too.

Stalled twice because of a pesky right calf strain, the 30-year-old third baseman returned from the disabled list Saturday in good health, in good spirits and with one really good swing: a three-run, 427-foot home run that spurred the Padres’ suddenly-not-so meager offense on to a 9-3 win over the Miami Marlins.

Yes, they still began the day ranked last in the majors in runs per game and last or second-to-last in average, on-base percentage and slugging percentage. But 19 runs the last two nights provides at least a glimmer of hope, what with this pitching-powered club owning a .923 winning percentage (12-1) any time they score at least four runs and the Padres seemingly days from adding Carlos Quentin to this mix.

“It’s really encouraging,” Headley said. “I think guys are starting to do what they are going to do. Guys are starting to settle down a little bit and have good at-bats. When you do that as a club, it really puts a lot of pressure on the pitcher.

“If we have the guys we expect to be in the lineup, I feel it’s a pretty good lineup.”

Another 13-hit attack paced Saturday’s effort, with Seth Smith’s cycle bid leading the way.

The Padres’ left fielder tripled, homered and doubled in a four-RBI game, Yonder Alonso reached base five times and Headley returned to action with a big bang to support Eric Stults’ first quality start in three weeks.

Better yet, Headley’s swings all night – as well as his takes – eclipsed his work through late April, when he was hitting .186 (13-for-70) with 20 strikeouts, six walks and five double-play balls upon tearing some of the scar tissue that built up following his initial calf injury this spring.

In addition to blasting his third homer of the season in the sixth inning off reliever Carlos Marmol (0-3) – who was designated for assignment after the game – Headley walked twice in five plate appearances.
