Amazon Prime has locked up a five-year exclusive deal for live telecast rights in the United Kingdom and Ireland for the U.S. Open Tennis Championships.

The deal will kick off with the 2018 U.S. Open and offer live and on-demand content to Prime members in both territories.

“This new partnership allows the USTA to showcase our live and on-demand content to Amazon Prime members throughout the U.K. and Ireland,” said Lew Sherr, USTA chief revenue officer, in a statement. “We are excited to market the telecasts via Prime Video and provide fans more ways to watch tennis matches.”

“Prime Video is focused on bringing customers a great selection of high-quality entertainment across drama, comedy, documentaries, live sports and more,” said Jay Marine, vice president of Prime Video Europe, in a statement. “We are delighted to now offer Prime members U.S. Open tennis at no extra cost to their membership, right alongside their favorite shows and movies.”

The tennis deal adds to Amazon’s expanding roster of sports available to stream live and on demand. This year, Prime Video launched UFC Pay-Per View events in the U.S. and will deliver live and on-demand coverage of the AVP Pro Beach Volleyball Tour and the Next Gen ATP Finals to customers in more than 200 countries and territories.

In June, Prime members in the U.K. and Ireland can watch live and on-demand content covering the ATP’s Queen’s Club Championships and Eastbourne International on Prime Video as part of an ATP partnership that will feature 37 ATP World Tour events annually beginning in 2019.
