Headley finds stroke, notches four hits vs. Giants

Using old grip, third baseman tallies biggest offensive game since 2012

SAN DIEGO -- Four on the fourth: not a bad way to celebrate Independence Day and certainly not a bad way to finish off an afternoon as far as Padres third baseman Chase Headley was concerned.

Headley had a season-high four hits and knocked in a run Friday as the Padres defeated the Giants, 2-0, on a sun-splashed day at Petco Park.

"Today you saw the line-drive stroke on all pitches," said Padres manager Bud Black. "Overall, his at-bats over the last two weeks have been better. I can't remember the last time we had a guy with four hits.

"That was a good one for Chase."

Headley raised his average 14 points with his biggest offensive day since Sept. 2, 2012, when he had four hits against the Rockies. Before Friday, he hadn't had more than two hits in a game this season.

"It felt good. I got some pitches to hit and had a good approach. ... It was nice to have one of those days," said Headley.

The Padres, who have won a season-best five consecutive games, have gotten huge contributions as of late from their pitching staff, which has compiled three shutouts in the last four games and four in the last 10 games.

What they have needed is for the offense to come around, including Headley, who began the day hitting .202.

Headley has recently made a mechanical fix of sorts that he hopes bodes well for the second half, as he's gone back to his old grip.

"It's my old funky grip, the one everyone made fun of," said Headley, a switch-hitter, of his grip, which has him lay part of one hand over the other.

It's the grip that worked so well for him in the second half of the 2012 season when he led the National League in RBIs (115).

"Now I just need some prolonged at-bats with it," Headley said.
