Reilly Opelka serves during his doubles match today at River Oaks

Reilly Opelka, the 18-year-old up-and-coming American tennis player St. Joseph, Michigan joins the Main Draw of the 2016 Fayez Sarofim & Co. U.S. Men’s Clay Court Championship. He replaces Dustin Brown, who withdrew due to a wrist injury. Earlier today, Opelka and doubles partner Tommy Paul (USA) both achieved their first ATP match victory. The young wildcard entrants defeated Nicholas Monroe (USA) and Neal Skupski (GBR) 7-6(6), 4-6, 10-4.

Opelka won the 2015 Wimbledon Boys’ Singles event, defeating Taylor Fritz en route to beating Mikael Ymer in the final. He also reached the finals of the Boys’ Doubles event (with Akira Santillan) at the 2015 Wimbledon Championships.

You can’t miss Opelka when he is on the court. In fact, he’s already being called “the next big thing in American tennis”; you see, he is just a bit over 6′ 10″. H is currently ranked No. 810 in the world, and at this point in his career, he serves in the mid-130 mph range. You can catch him on the court tomorrow, when he faces Sam Querrey.
