MILWAUKEE -- As it turns out, it wasn't just cramps in both of his legs that forced Padres pitcher Edinson Volquez from his start Sunday against the Giants.

"They were everywhere," Volquez said.

Volquez threw one pitch in the fifth inning of Sunday's loss before being removed from the game.

On Monday, Volquez said that he had felt fine warming up and in the first two innings. In the third inning, though, he started to feel some cramping in his legs. Later on, that cramping extended to his calves, hamstrings and his left oblique.

"I was pretty sore," he said. "In that fourth inning, it was pretty bad."

Volquez allowed two runs on six hits in four-plus innings. He didn't factor in the decision and finishes his first season with the Padres with an 11-11 record and a 4.14 ERA in 32 starts.

"I was pitching against one of the best pitchers in the game [Giants' starter Tim Lincecum] and I wanted to stay out there and compete," Volquez said. "It was our last home game, and I wanted to stay in there for the fans."

Shut down by Friars, Kelly will miss start, AFL

MILWAUKEE -- Rookie pitcher Casey Kelly won't make his scheduled start Tuesday and will likely miss the upcoming Arizona Fall League after the team decided Monday to shut him down.

Anthony Bass will get the start in Kelly's place against the Brewers.

San Diego manager Bud Black said that Kelly's right arm has not "bounced back the last couple of starts to where we felt one more start would be worth it."

Kelly, who missed three and a half months of the season with a strained right elbow while pitching in the Minor Leagues, was scheduled to pitch later this month in the Arizona Fall League to pick up innings that he missed when he was on the disabled list as well as work on a changeup.

But now the goal for the 22-year-old will be to have a restful offseason with an eye on reporting for Spring Training healthy and competing for a spot in the starting rotation.

"For Casey, the most important thing is 2013," Black said. "The 30 or 40 innings he would have pitched [in the Arizona Fall League] are not as important as 2013."

Kelly was 2-3 with a 6.21 ERA in six starts after joining the team on Aug. 27. He began the season with Triple-A Tucson and made two starts before going on the disabled list in April.

"Even though the volume wasn't there, we saw some good quality," Black said.

Bass, who made 14 starts earlier this season before landing on the disabled list in June with an inflamed right shoulder, will likely throw between 40-60 pitches, Black said. From there, Black said the Padres will cover the rest of the game with relievers.

"He's not stretched out like some starting pitchers, but he's got a starter's mentality," Black said of Bass.

Headley hardly slowed from August to September

MILWAUKEE -- The reigning National League Player of the Month may have positioned himself to win the award again for the month of September.

San Diego third baseman Chase Headley drove in a run in Sunday's loss to the Giants, giving him 30 for September. He knocked in 31 runs in August.

The only other Major League player to register 30 or more RBIs in two consecutive calendar months was Albert Pujols in April-May 2006, when he was with the Cardinals, according to Elias.

Headley is the first player with two 30-RBI months for the Padres, not only in consecutive months and not only in two months within one season, but in his career with San Diego.

In August, Headley hit .306 with 10 home runs, 31 RBIs and a .345 on-base percentage. For September, Headley hit .324 with nine home runs and 30 RBIs to go with a .410 OBP.

"That was as good a two months as you'll have," said Padres manager Bud Black.

Headley got a ringing endorsement from Brewers manager Ron Roenicke before Monday's game at Miller Park.

"To have that [production] in San Diego, that's pretty amazing," Roenicke said. "He needs to be talked about a lot more than he has been. To have that kind of year in that place? Phenomenal."

Black, knowing Monday's game against the Brewers marked the start of three games to end the regular season, offered a joke at Headley's expense.

"I hope he has a great October," Black said, smiling.

Results of the voting will be announced on Tuesday.
