As Milos Raonic prepares for his Wimbledon quarter-final, his descendants continue their quest in the juniors

WIMBLEDON – The second Tuesday at Wimbledon – assuming everything is on schedule – is a relatively quiet day on the singles side. Only the women are in action – and we say this not to denigrate their efforts, but to point out that this is the first day of the tournament that both the men and women aren't scheduled.

Milos Raonic will be first up on No. 1 Court Wednesday against No. 28 seed Sam Querrey, the heavy favourite to advance to the semi-finals despite the fact that Querrey was the one who sent Novak Djokovic home in the third round.

We flash back to their first career meeting, which coincidentally came at WImbledon, in the second round in 2012. Raonic was just 21 then, Querrey three years older and fresh off a win over Raonic's countryman  Vasek Pospisil in the first round.

The difference between then, and now, tells you all you need to know about how much Raonic has evolved.

Raonic had beaten Santiago Giraldo over two days in that first round that year. And when asked afterwards if he would consult with Pospisil and his then-coach, Canadian Fred Niemeyer about how Querrey was playing and what he did to defeat Pospisil just hours before, Raonic was dismissive. He was in his Spanish phase, then, and everything the Spanish players did or coach Galo Blanco said was gold. He said Blanco would know Querrey and, if he didn't, one of the other Spanish players would.

And that was that; Raonic went out and lost to Querrey in four sets, his poor serving making Querrey "look like a better returner than he was," as he put it later. Raonic was camped well behind the baseline while Querrey was right on top of it. Raonic said afterwards that his ego got in the way a little bit, that he had failed to put everything aside, play with humility and worry less about playing well and more about getting the job done.

It sounds like an incubating version of the present-day Raonic, but he's evolved so much in four short years. He will take the court Wednesday with a developed game plan, a number of consultants to give him some input, and an expectation that if he executes, he will win.

Meanwhile, Pospisil is out of the men's doubles in the third round, after a 6-4. 3-6, 6-7(3), 7-5, 6-4 loss with partner Jack Sock to the French team of Edouard Roger-Vasselin and Julien Benneteau. That pair, a top-10 doubles team by most standards, are playing on a protected ranking after Benneteau had an extended injury absence. That makes them a very dangerous unseeded duo, who can beat any of the teams out there on any given day.

Still, Pospisil and Sock had match points in the fourth set. 

Gloucester Ont's Gabriela Dabrowski is also eliminated. She and American partner Nick Monroe lost in the third round of the mixed doubles after Dabrowski and women's doubles partner Maria José Martínez Sánchez lost in the second round. They defeated Eugenie Bouchard and Sabine Lisiski in the first round, but fell in three sets to the all-Spanish pair of Anabel Medina Garrigues and Arantxa Parra Santonja – despite being up a set and 4-0 in the second.

On the juniors side only Charlotte Robillard-Millette is out, gone in the second round after a heartbreaker of a 6-4, 5-7 9-7loss to 15-year-old Olga Danilovic of Serbia, the No. 10 seed in the girls' singles draw.

Here's what the juniors looked like Tuesday.

Unlike Robillard-Millette, who is playing more pro events and hasn't been fully invested in the juniors, Danilovic is only playing junior tournaments. And she's won a ton of matches this year. She has some powerhouse Spanish support behind her in Alex Corretja, and she defeated Robillard-Millette in the first round of the French Open, but by the far more lopsided score of 6-0, 6-4.

Montreal's Félix Auger-Aliassime faced one of his toughest rivals in the second round Tuesday, prevailing over Nicola Kuhn of Spain 7-6 (5), 6-3. Kuhn and Auger-Aliassime both have 2000 birthdays, and they've met on some big occasions over the last nine months, including the junior French Open and the junior Davis Cup finals last fall in Madrid.

Auger-Aliassime's doubles partner Denis Shapovalov took care of British wild card Finn Bass 6-1, 7-5, in a match that its share of drama. Auger-Aliassime and Shapovalov, who are the No. 1 seeds in doubles, teamed up later in the day to win their first-round doubles match.

Meanwhile, top Canadian junior girl Bianca Andreescu, who turned 16 less than three weeks ago, rolled into the third round of the junior girls' sincles with a 6-4, 6-4 win over Paula Arias Manjon of Spain.

Andreescu withdrew from the junior Australian Open back in January with a stress fracture in her foot, and only returned to action last week at the warmup grass-court tournament at Roehampton.

Vancouver''s Ben Sigouin, who lost a tough first-round match in singles, also advanced to the second round in doubles with German partner Louis Wessels.

Wednseday at WImbledon, in addition to Raonic, Adil Shamasdin willl try to get to the men's doubles semi-finals with British partner Jonny Marray.

The pair had a day off Tuesday after their dramatic five-set marathon in the third round on Monday. They will play No. 12 seeds Treat Huey of the Philippines and Max Mirnyi of Belarus, with more than a puncher's chance of winning.

Andreescu, Shapovalov and Auger-Aliassime all will play their third-round singles matches, while Robillard-Millette begins her doubles campaign with Indian partner Karman Thandi.
