Caroline Wozniacki -- Serves Up Smokin' Hot Bod ... In SI Swimsuit Edition

Hey Rory ... you seein' this?

Check out these pics of tennis superstar Caroline Wozniacki -- featured in her very own spread in the Sports Illustrated Swimsuit Edition.

It seems Wozniacki's really let loose since golfer Rory McIlroy broke off their engagement last year -- she's been on several girls-only trips with her BFF Serena Williams ... and started posting all sorts of hot bikini selfies.

And now she's upped her game in the new SI pics ... even showing off her ass.

Caroline isn't the only athlete in the mag -- UFC badass Ronda Rousey also got a spread.

Stay tuned for those, but in the meantime ...
