HOUSTON -- If you follow the Astros on just about any social media platform, you know the team is pushing relentlessly in its quest to get left-handed pitcher Dallas Keuchel some help to win a spot in the All-Star Game.

Keuchel, who has been the Astros' top starting pitcher this season, is one of five American League players -- joining Cleveland's Corey Kluber, Detroit's Rick Porcello, Chicago's Chris Sale and Los Angeles' Garrett Richards -- who will take part in the Final Vote, where fans decide who gets the last roster spot. He's certainly deserving of his first All-Star nod, going 8-5 with a 3.06 ERA in 16 starts this year, including three complete games.

"We're basically doing a multi-platform really big social media push," said Astros social media manager Amanda Rykoff said. "Twitter will be the main focus and the easiest call to action. We'll have a different sweepstakes each day with different prizes for fans for voting."

The Astros will be active on Facebook, too, trying to push Keuchel with sweepstakes on Wednesday and Thursday. The club has teamed up with the Marlins to promote Casey McGehee for voting in the National League Final Vote.

"It's very nice both of the two beards are in the Final Vote," Rykoff said. "We're working on putting together new avatars for fans to put on Twitter to show support."

Astros mascot Orbit and Billy the Marlin have been working together to promote each player, as well. The Astros are saving their biggest promotion for Twitter on Thursday, when the voting really heats up, with hourly sweepstakes for Keuchel-related prizes.

Look for Houston celebrities, such as rapper Bun B, and other area pro sports teams to get involved in the Keuchel campaign, too.

"He has some great numbers, and obviously it's a loaded field and all the American League pitchers on the Final Vote make strong cases, but certainly Keuchel's numbers are right there," Rykoff said.

Manager Bo Porter said he's been voting for Keuchel, and teammate Jarred Cosart has been pushing the cause.

"I told my mom and my family members to vote," Cosart said. "It's pretty cool. I gave him a shout-out on Twitter, too. Obviously, it would be great to see him get in there. We all want to see him get in there."

As for Keuchel, he's taking all the attention in stride.

"It's nice to see the support I've been getting," he said. "Regardless of what happens, I appreciate everything that everybody's been doing for me."
