LOS ANGELES -- After throwing two bullpen sessions last week, All-Star closer Huston Street made the decision to ramp up his recovery from a left calf strain by doing some sprints last Thursday.

That proved to be a bad idea, as Street experienced soreness in his calf, a setback that has aggravated him to no end.

"It's frustrating because you want to play," said Street, who has been on the disabled list since Aug. 11. "If I could figure a way to crawl to first [base] fast enough, I'll do it."

Street's arm is fine, but the team is still cautious about his ability to run and make cuts on the strained calf, which feels considerably better than it did two weeks ago.

"We're going day to day until we get a plan," Street said.

San Diego manager Bud Black certainly sympathized with Street, who was the Padres' lone All-Star and has missed a total of 50 games with two DL stints. He missed 29 games earlier in the season with a strained right lat muscle.

"He's a little bummed," Black said. "He thought he'd make a quick recovery based on where he was last week. But it's the break to cover a bunt or cover first, that's something that's getting him."

Prospect Asencio claims batting title at Class A

LOS ANGELES -- Fort Wayne outfielder Yeison Asencio captured the batting title for the Padres' Class A affiliate on Monday, becoming the first player in the organization to win a full-season batting title since Chase Headley hit .330 for Double-A San Antonio in 2007.

Asencio, 22, had one hit in two at-bats in the first game of a doubleheader against Bowling Green on the final day of the regular season to finish with a .323 average. He edged Kevin Pillar of Lansing by a single point (.322).

In November, it was revealed that Asencio had been using a false identity -- Yoan Alcantara -- and an age that was 2 1/2 years younger than he actually was. Asencio will turn 23 on Nov. 14.

Asencio's season didn't begin until May, when he obtained his visa in the Dominican Republic, though he picked up where he left off in 2011, when he hit .348 for the Padres entry in the Arizona League.

"Coming out of last year and the problems we had over the offseason, Yeison showed up and picked up where he left off [in 2011] with really no Spring Training," said Randy Smith, the Padres' vice president of player development and international scouting.

What does Smith like about Asencio's game?

"He has the ability to barrel the baseball from his neck to his toes," Smith said. "He's a very aggressive, hits the ball extremely hard and doesn't strike out. But, conversely, he doesn't walk. He's a hitter."

Asencio hit eight home runs and drove in 61 runs for the playoff-bound TinCaps. He also had more than 20 outfield assists as a right fielder.

Asencio didn't back into his batting title. He had eight hits in his last 23 at-bats, including three multi-hit games.

"What I liked was that coming into the last few days, he knew he had to get some hits to win the batting title and he flat out did," Smith said.

Quentin scratched from opener with knee irritation

LOS ANGELES -- Left fielder Carlos Quentin was a late scratch Monday with what the Padres termed right knee irritation.

Quentin, who had surgery on the same knee in Spring Training, was busy during three-game weekend series at Coors Field against the Rockies, chasing fly balls, base hits and was also active on the bases.

"A lot of action in left in Colorado," Padres manager Bud Black said.

Quentin, who is hitting .265 with 15 home runs and 43 RBIs, didn't join the team until May 28, more than two months after having arthroscopic surgery.

"It's a flare-up," Black said. "You could still see him tonight in a pinch-hitting capacity."

Quentin did get a pinch-hit at-bat, lining out to center field in the top of the 11th in the Padres' 4-3 loss to the Dodgers.

Chris Denorfia got the start in left field for Quentin.

Short hops

• Andrew Cashner, who missed 51 games with a strained right lat muscle, will start Friday against the D-backs at Petco Park. Oddly enough, the injury occurred during a start against the D-backs on July 3. With Cashner starting, the Padres will use a six-man rotation. With four off-days this month, this will give the rest of the starters an additional day of rest. Cashner was 3-3 and had a 3.44 ERA before his injury, with a 2.53 ERA in three starts after moving into the rotation.

• The team will add pitcher Anthony Bass to the roster on Tuesday. Bass allowed three earned runs in three innings of a Minor League rehab start Sunday for Triple-A Tucson. He will slide into the bullpen, said Padres manager Bud Black. Brad Boxberger, a reliever, will also join the team as will infielder Andy Parrino and catcher Ali Solis. The Padres will have three catchers on their roster with Solis, John Baker and Yasmani Grandal.
