SD@COL: Decker hammers his first career home run

DENVER -- Ask Padres rookie outfielder Jaff Decker, and he will be the first to acknowledge home runs are not a big part of his game, which probably made the one he hit Monday at Coors Field that much more enjoyable.

"Doubles are kind of my thing," Decker said Tuesday, a day after he made the most of his first Major League hit, a seventh-inning solo home run in a 14-2 loss to the Rockies. "That's what I've been working on, and that's what I was doing in this half [second half of the season with Triple-A Tucson] when I started to swing it better.

"I have it in me, but I don't try and be a home run hitter anymore."

Decker had nine home runs in 331 at-bats this season with Tucson. He reached double-digits in home runs three times in the Minor Leagues, hitting 19 with Double-A San Antonio in 2011.

Decker said Tuesday afternoon that he was still receiving phone calls and text messages after hitting his first home run, also his first Major League hit.

"They're still coming in; It's a good feeling," he said. "A lot of friends were watching the game at home [Arizona] and saw it live. I got a lot of phone calls from some old friends."

Decker's father, Kent, was in Cincinnati over the weekend to see Decker's first start Sunday, when Decker went 0-for-3, before returning to the family home in Arizona.

"Luke [Gregerson] said he's not allowed to come now," Decker said, smiling.

Volquez to stay in Padres' starting rotation

BAL@SD: Volquez fans six over six solid frames

DENVER -- Edinson Volquez, who has the highest ERA among qualified Major League starters, will remain a part of the Padres' starting rotation for the time being.

"Right now, we're keeping our rotation in order as we go through the week," Padres manager Bud Black said. "We'll see. We talk about our players all the time, on an everyday basis, with the coaches and with [general manager Josh Byrnes and assistant general manager A.J. Hinch].

"It's an evaluation process every day."

Volquez allowed eight earned runs in 4 1/3 innings in Monday's 14-2 loss to the Rockies, raising his ERA to 5.80 in 25 starts. Only Volquez, the Orioles' Jason Hammel (5.20) and the Cubs' Edwin Jackson (5.05) have ERAs over 5.00 among starting pitchers with at least 118 innings.

Volquez is 8-10 and has made all 25 of his starts. He is also allowing 10.3 hits per nine innings.

Black said the Padres would have an influx of pitchers joining the team after Sept. 1, when the rosters expand from 25 to 40 players.

"We'll bring some arms back to the big leagues that we've seen this year, and there might be a couple of additions to our roster that we haven't seen this year," Black said.

Black said a six-man rotation in September was not out of the question.

"That wouldn't be too far-fetched at all," he said. "Or something where a couple guys get extended rest between starts or we skip a pitcher and have him pitch on a 10th or 11th day."

That could mean pitchers like Robbie Erlin, Burch Smith and Anthony Bass could rejoin the team. Those three are already on the 40-man roster. Keyvius Sampson and Matt Andriese, who aren't on the 40-man roster, could merit consideration.

Quentin likely to return but not right away

SD@ARI: Quentin's RBI single puts Padres on the board

DENVER -- Left fielder Carlos Quentin, who has not played since July 30 because of a right knee strain, will not come off the disabled list Thursday, when he is first eligible.

San Diego manager Bud Black said Tuesday that Quentin was still experiencing some soreness in his knee. Quentin tested the knee Friday and Saturday in Cincinnati and reported soreness afterward.

"Carlos is in a situation where for him to do any baseball activities, it's painful, especially the defensive or on the running side," Black said. "He can get into his stance and hit, but we're staying away from that just to let the knee heal. He's feeling better but not to the extent where he can get on the field."

Black is hopeful that Quentin can return again this season, and he does not think this latest setback with Quentin's surgically repaired knee will keep him from playing again in 2013.

"I haven't heard anything close to that from the medical department that we're not going to see him; I'm optimistic we'll see him," Black said.

Quentin was hitting .273/.363/.493 in 82 games with 13 home runs and 45 RBIs.

The Padres' offense has struggled without him. In the 10 games Quentin has missed, the team has scored 27 runs and left 70 runners on base. In the last six games alone, the team is 3-for-55 with runners in scoring position.

"He hits in the middle of our order; he's a guy we count on for productivity," Black said, adding that "without him not in there, our other guys need to be productive. It's been awhile where we've sustained any consistent offense."
