Daily Bagel: How has Grigor Dimitrov turned into such a force at Slams?

The Daily Bagel is your dose of the interesting reporting, writing and quipping from around the Internet.

• Video: Everything you need to know about Rafael Nadal in one video. Nadal's focus and competitiveness as he juggles the ball for what seems like forever, is amazing. 

• Roger Rasheed talks about the new fitness regime that has turned Grigor Dimitrov into a force at the Grand Slams.

Rasheed's approach to training is simple: suffer or don't bother.

"If you're not prepared to be redlined in the off season, well then, don't turn up," he said. "I don't want to hear any excuses."

Dimitrov isn't making them. He sounds more like someone who has developed an addiction.

"I enjoy working with him," Dimitrov said. "I think sometimes it's not even enough."

In tennis, beautiful strokes are both a blessing and a burden. Fans love them. So do coaches and scouts. If those strokes don't help a player win, though, the criticism a player endures is usually harsh. Though Dimitrov's game can't be anything less than pretty, he's less concerned with style these days.

"In the end it doesn't matter if you're going to win crappy or if you're going to lose beautiful," he said. "I'd rather win."

• Doug Robson for USA Today on why Andy Murray may have found a kindred spirit in Amelie Mauresmo, who sat under the glare of intense scrutiny after coming out at 19.

Rennae Stubbs, the out lesbian from Australia who comments for Tennis Channel, said the grace with which Mauresmo handled her disclosure was probably a "small factor" in Murray's decision to bring her onto his team. But a factor nonetheless.

"He recognizes she's somebody who's pushed envelopes along the way," said Stubbs, a former No. 1 in doubles.

Like Mauresmo, Murray felt the sting of notoriety in his career. The Scot talked of how excited he was to be living his dream when he began competing on the pro tour.

"I had no problems," he said. "I felt pretty free. There was no pressure."

But the media scrutiny in Great Britain, starved for a champion, took a toll.

"It became hard for me," Murray said. "I didn't feel like I was represented fairly. ... I went into my shell. I didn't feel like I could express myself at all. I became very defensive because I felt like I was getting criticized about not just my tennis but my hair, the way I looked, what I was saying."

• From Simon Cambers for The Guardian, Olga Morozova, who worked with Murray when he was younger, hopes hiring Mauresmo opens up more doors for women in coaching.
