Chapman picks up first Major League win

SEATTLE -- Lost amidst the Astros' ninth-inning comeback Monday and the revelation that pitcher Jarred Cosart had made his final start of the season was yet another first Major League win for an Astros pitcher. This one was by left-hander Kevin Chapman, who threw a scoreless inning.

Chapman is the seventh Astros pitcher to collect his first Major League win this year, joining Cosart, Brett Oberholtzer, Jose Cisnero, David Martinez, Josh Fields and Paul Clemens. Chapman earned his first save Aug. 18.

"I didn't come out of the game expecting anything," Chapman said. "We were down a run and everybody had great at-bats and we were able to get some runs."

Chapman entered Tuesday with a 2.19 ERA in 16 career appearances and began his career by not allowing an earned run in his first 13 outings (9 2/3 innings). He's allowed only one hit to a left-hander (1-for-18).

"It's just an ongoing process that never stops," Chapman said of his season. "I don't like to sit there and look at what I've done or haven't done. I like to come in every day and find a way to get better and stay as consistent as possible, and at the end of the year you can look back and see what you did right and see what you did wrong."

Clemens' recovery to impact rotation decision

SEATTLE -- Having shut down rookie right-hander Jarred Cosart for the remainder of the season after he threw a career-high workload this year, the Astros still haven't determined whether they will continue with a six-man rotation or go with a five-man rotation the rest of the way.

That decision will have a lot to do with how right-hander Paul Clemens feels after throwing a bullpen session Tuesday. He was scratched from his start Sunday in Oakland with a blister. The Astros have yet to set their rotation for this weekend's series at home against the Angels.

"We're going to get through the off-day [Thursday] and make a decision whether or not we're going to stick with six or go to five," manager Bo Porter said. "Clemens is going to throw [Tuesday], and we'll know more after he throws whether or not he's going to be able make his start."

If Clemens is able to pitch, he would start Saturday against Angels and would split left-handers Dallas Keuchel (Friday) and Brett Oberholtzer (Sunday). Among the candidates to perhaps be added to the rotation is rookie David Martinez, who was recently called up from Triple-A for his second stint with Houston.

Porter said the Astros aren't planning to shut down any additional starting pitchers because of their workload.

Astros to slip on dancing shoes for fundraiser

SEATTLE -- Tickets are still available for Sunday's Dancing with the 'Stros event at the House of Blues in downtown Houston, but they must be purchased in advance of the event.

Astros players Jose Altuve, Jarred Cosart, Dallas Keuchel, Jake Elmore and Trevor Crowe will trade in their cleats for dancing shoes in a team charity fundraising event. The five players will be paired with professional dancers to learn a routine in the dance style of their choosing after just one hour of rehearsal. The Astros players will be judged by their teammates.

The event will highlight the new strategic focus of the community partnership between Houston-based Minute Maid and The Astros Foundation to support an expansion of programming and outreach for at-risk youth by the official team charity's Urban Youth Academy in Houston. Details of the new partnership will be announced by Minute Maid president Mike Saint John at the event.

In addition to all of the 2013 Astros players, the team's owners, coaches, executives and alumni will be on hand, as well as Minute Maid executives and employees, Comcast SportsNet, generous sponsors, Astros fans and local charitable champions.

The doors open at 6 p.m., and the event will begin at approximately 7 p.m., subject to the end time of Sunday's 1:10 p.m. game.

Advanced ticket purchase is required because tickets will not be available at the event. Door prizes also will be given away during the reception prior to the show. Sponsorships and a limited number of individual tickets are available for purchase, and because this is a charitable fundraiser, a portion of the ticket cost is tax deductible. Ticket information is available at www.astros.com/dancing or by calling 713-259-8851 before Friday.

Proceeds from this fundraiser will benefit The Astros Foundation's Urban Youth Academy. The nonprofit program provides free, year-round baseball and softball instruction, mentoring and leadership development for at-risk and low-income youth at the UYA facilities in the Acres Homes neighborhood of Houston and at clinics at neighborhood parks operated by the Houston Parks and Recreation Department throughout the city.
