Phil Schiller teased an augmented reality overlay on a live baseball game during the iPhone 8 keynote presentation. Fans viewing the match could instantly see things like how far a ball was thrown, how hard it was hit and how fast a player is running.

But while those features are coming to the MBL At Bat app, fans won’t get them until the 2018 season …

CNET’s Terry Collins didn’t waste any time when he saw it in the keynote.

That got them both an invitation to see it in use during an actual game between the San Francisco Giants and the Colorado Rockies, but fans won’t get their chance to do the same until next year.

But it sounds like it will be worth the wait. As well as showing live game data, it will also integrate stats from Stacast.

However, deciding where to draw the line is one of the reasons it will take a while to ready it for launch.

Statcast gives teams, broadcasters and fans an array of metrics and trivia, including that New York Yankees rookie Aaron Judge’s 495-foot home run is the longest this season. Or how his teammate Aroldis Chapman has thrown the season’s fastest pitch at 105 miles per hour, with the ball spinning a dizzying 2,600 times after it left his hand.

MLB At Bat is a free download from the App Store, though you’ll need in-app purchases to unlock premium features, including live MLB games.
