With baseball season in full swing, Hankook Tire is celebrating America’s pastime by giving fans the opportunity to win prizes through its “Retweet to Win” Twitter sweepstakes.

For the chance to win Hankook swag, fans can follow @HankookUSA on Twitter, watch for unique baseball-themed images with the #HankookSweeps hashtag in them, and then retweet those images.

Here’s how it works:

• Each week through the end of July, @HankookUSA will post at least two eligible tweets with the #HankookSweeps hashtag.
• Fans enter the sweepstakes by retweeting any or all of the eligible tweets in their entirety. Each re-tweet is an additional entry to win.
• Every Monday through Aug. 3, Hankook will randomly select a winner, and announce the winner via @HankookUSA on Twitter.

Winning fans will each receive a Hankook Tire backpack full of swag such as hats, T-shirts and tire gauges. The Hankook Tire Twitter sweepstakes runs June 22 through July 31.
