SAN DIEGO -- The Padres added who figures to be their last player to the active roster on Tuesday in relief pitcher Erik Hamren from Triple-A Tucson.

Hamren is no stranger to San Diego, having spent nearly a month with the team before being optioned to Tucson on Sept. 6.

Hamren, 25, said he's more prepared to pitch at the Major League level now than he was after being promoted to the Padres from Double-A San Antonio on Aug. 30.

"There's not the shock value of it. ... My feet are wet. I'm settled in," Hamren said. "It's something you've dealt with before."

Hamren, a right-hander, had a 2.79 ERA in 10 appearances and picked up his first Major League victory on Aug. 23 against the Giants at AT&T Park.

Hamren struck out nine and allowed five hits in 9 2/3 innings with seven walks, though that statistic is a little misleading since three of the walks came in one relief appearance during his second big league game in Pittsburgh on Aug. 5.

"If you really look at it, the walks came in two games ... and if you take those away, it's not that bad," Hamren said. "I try not to stress myself out about it."

Hamren, who a year ago was pitching in the independent Northern League, was 5-1 with a 1.05 ERA in 50 games this season between stints with Class A Lake Elsinore, San Antonio and Tucson.

"This is the first year that things have fallen into place for me, where I've started locating better," Hamren said. "I think that it's been a matter of getting more repetition and getting settled."

Headley will start swinging this weekend

SAN DIEGO -- Padres third baseman Chase Headley hasn't taken a swing in a game since Aug. 6, felled by a fractured left little finger that landed him on the disabled list two days later.

On Tuesday, Headley discovered he could swing a bat again this weekend, even if it means hitting balls off a batting tee or playing flip in the batting cage.

A visit to a hand specialist revealed positive results with Headley's finger, meaning that he will be able to pick up a bat Saturday, when the team is in Phoenix playing the D-backs.

"It's going in the right direction," Headley said on Tuesday before the Padres faced the Giants at PETCO Park. "It feels like it's been months."

There's no timetable as to when Headley will be cleared to take batting practice or when he'll be allowed to play again.

Headley suffered the fracture when he hooked his finger on the second-base bag while sliding into the base against the Pirates. He is hitting .292.

Four affiliates make postseason

SAN DIEGO -- Four of the Padres' Minor League affiliates are heading to the postseason.

Double-A San Antonio, which won the first- and second-half titles in the Texas League's South Division, opens the playoffs on Wednesday at home against Frisco, the affiliate of the Rangers.

Class A Lake Elsinore clinched a spot in the California League playoffs. The Storm will visit Inland Empire (Angels) on Wednesday.

Class A Fort Wayne opens the Midwest League playoffs Wednesday against Bowling Green (Rays) at home.

Finally, short-season Eugene of the Northwest League won the first game of its series against Vancouver (Blue Jays) on Monday, 8-3. The teams play again Tuesday.

The Padres' starting lineup on Tuesday against the Giants included five players who started the season in the Minor Leagues -- first baseman Jesus Guzman, left fielder Kyle Blanks, third baseman James Darnell, second baseman Andy Parrino and starting pitcher Wade LeBlanc.

Worth noting

• Steve Webber, the pitching coach for Triple-A Tucson, joined the Padres' coaching staff on Tuesday. He'll spend the final month of the season with the big club now that the Pacific Coast League season has ended.

• Third baseman Logan Forsythe is close to returning to the lineup. Forsythe hasn't played since Aug. 31 because of inflammation in his right patellar tendon.

"He's getting close," Padres manager Bud Black said.

• Rookie James Darnell got the start at third base on Tuesday.
