It's time for the seventh inning stretch!

We've been counting down to Boston's opening day by having listeners call in to the Shark Morning Show to answer baseball-related trivia to win some prizes.

Now we're upping the ante with an exclusive app contest.

We want to give away a grand slam prize to the Crossings in Newington: $50 to Longhorn Steakhouse, $50 to Dick's Sporting Goods, a 2018 World Series official dvd, and some commemorative baseballs.

Here's what you need to do to win.

First, make sure you've downloaded our app, as this will be the only way to enter the contest. Then, starting March 25, a button titled "Grand Slam" will appear on the main page of the app. Click on that button, and you'll be taken to a page where you can enter the contest.

The contest will also be found in the side menu of the app.

It's that easy!

One entry per person. Contest ends April 9.

Remember, you must have downloaded our app to enter!
