Follow rest of the season on At Bat for just $4.99

While the Nationals still hold onto a significant lead in the National League East, Adam Bayes is following his favorite team in a new way this summer.

The 34-year-old fan recently moved from Arlington, Va., to Charlotte, and the At Bat app has been a crucial companion. Major League Baseball Advanced Media just lowered the price to $4.99 through 6 a.m. ET on Tuesday as part of a special Labor Day Sale, clearing the way for even more fans to follow the pennant races the way Bayes has with a sports app standard bearer. That's a 50 percent savings and the price of At Bat will go back to $9.99 following the sale.

"I use At Bat on my iPad and iPhone," he wrote in an email to "I'm married and have two kids and own and operate a small business, and I am often not able to sit in front of a television for long periods of time. So it's nice to be able to keep up with the game, even if it's just checking the Gameday updates or listening to Charlie and Dave on 106.7 The Fan -- the club's official radio broadcast -- through the app's radio feature.

"Since I can't listen to local radio in North Carolina, I can access the broadcast through the radio feature and feel like I'm not missing anything. During the recent winning streak, I was able to keep up with the games even if I couldn't watch every second of every game. I feel like the app has made it easier to keep up with my home team even when I am in a different state."

At Bat entered this year as the highest-grossing sports app five years running, bringing baseball to the iPhone, iPad, supported Android smartphones and tablets, Amazon Kindle Fire, BlackBerry 10 and Windows Phone 8. Available since it became one of the original 500 apps to launch with the Apple App Store on July 10, 2008, At Bat has continued to soar in popularity.

It was downloaded 5 million times during the first week of this season, a record-setting total 25 percent higher than last season's comparable. In addition, At Bat and MLB.TV combined to deliver 94 million total video streams, a mark 88 percent higher than the record set in the first week of the 2013 season.

On Tuesday, Cardinals fan Bryan Williams of Louisville summed up the sentiment of many with this single tweet: "The At Bat app is pure perfection."

It also is an ideal back-to-school gift for parents wanting to use the app's new give-as-a-gift capability. "When I'm busy being buried in homework," Cardinals fan Danielle Kemper tweeted, "I'm always thankful for my At Bat app to keep me posted on what's going on."

By taking advantage of this special offer, you have access to every decisive instant replay video clip and review explanation via Gameday. You also have access to such features as personalized team experiences to deliver a linear feed of content for a designated favorite team; searchable libraries of tens of thousands of video-on-demand highlight clips; and customizable original news reporting and fantasy baseball analysis from club beat reporters and national columnists.

Since it became the first app to stream live video in 2009, At Bat has introduced an evolving set of ways for its millions of subscribers to consume live baseball games. MLBAM provides blackout-free live look-ins, in-game highlights delivered to At Bat in less than 60 seconds, the free MLB.TV Game of the Day, live statistical overlays such as pitch tracking and an archive of Classic Games, and more cool features.

For the third year, MLB.TV Premium subscribers again receive At Bat for free, unlocking the app's premium feature set.

"Wherever I am, so is my game," said country music star Jason Aldean, who has At Bat with him throughout his summer-long "Burn It Down" tour. "Now it's cool, because it's kind of anywhere you go, you've got it right there. You can be walking down the street and pull [an iPhone] out and be watching on your phone. ... I can keep up with everything."
