It’s game, set, heartbreak for Russian tennis star Maria Sharapova.

The blond beauty confirmed Friday that she and former Nets player Sasha Vujacic called off their engagement and that she has been on her own “since the end of spring, actually.”

“I was waiting for someone to actually ask me that question, but nobody did, directly,” she said. “It was obviously a challenging decision, you know, from both of our ends.”

C.J. Watson recently tweeted out a picture of his diploma.

Six years after leaving Tennessee to pursue his dreams of being a professional basketball player, the Nets guard now holds a Bachelor of Arts degree in psychology from the university.

“Every year since [I left] I’ve been going back and doing classes every summer,” Watson told the Post on Friday in a phone interview from Johannesburg, South Africa, where he’s participating in Basketball without Borders. “This summer I didn’t have to go back to campus, I could do it online.

“It feels great. It feels like a little burden off my shoulders. I’m glad that I’ve got it over and done with.”

Kawhi Leonard, future star?

Fan Question: What kind of season do you see Kawhi Leonard having next season? Also, where do you see him in five years?

San Antonio Spurs coach Gregg Popovich: I think he’s going to be a star. And as time goes on, he’ll be the face of the Spurs I think. At both ends of the court, he is really a special player. And what makes me be so confident about him is that he wants it so badly. He wants to be a good player, I mean a great player. He comes early, he stays late, and he’s coachable, he’s just like a sponge. When you consider he’s only had one year of college and no training camp yet, you can see that he’s going to be something else.

According to Sportando, “Jacob Pullen won’t play in the Euroleague next season with Serbian Partizan Belgrade but in Israel with EuroCup regular Hapoel Jerusalem, as reported by David Pick. The ex-Kansas State combo guard who spent his pro rookie season in Italy’s Seria A with Angelico Biella, agreed to join Jerusalem over a tempting offer from Euroleague’s Partizan. The Chicago native will enjoy Jerusalem’s two games per week schedule, competing both in the Israeli Domestic League and the EuroCup competition.”

Former Wake Forest forward Josh Howard is doing some workouts with the Charlotte Bobcats this week, president of basketball operations Rod Higgins confirmed.

The Bobcats’ interest in Howard is still exploratory, as they consider ways to fill out their roster. The Bobcats would like to have another power forward, and have previously considered Antawn Jamison, Kris Humphries, and Carl Landry, who all signed elsewhere. Howard, 6-7, has played both power and small forward.
