The article cites four, but 2 from WTA.
No. 8 Stanislas Wawrinka vs. No. 10 Jo-Wilfried Tsonga
Head-to-head: Tsonga leads 3-2
Two things usually happen when these two meet: Dynamic tennis erupts and the match goes the distance.
At the 2011 French Open, Wawrinka roared back from a two-set deficit to beat Tsonga. In their French rematch a year later, Tsonga halted another Wawrinka comeback with a 6-4, 7-6 (6), 3-6, 3-6, 6-4 triumph in a match that spanned four hours spread out over two days, with both guys splattering winners across the red clay.
Because both are strong servers -- Tsonga was fourth on the ATP in service games won (88 percent), Wawrinka was 11th (85 percent) -- breaks can be scarce. They were born 20 days apart and their meetings can come down to tactical imposition.
Wawrinka wants to work Tsonga over in backhand exchanges, because Stan’s one-hander is a much more reliable and penetrating shot than Jo’s two-hander. Tsonga, whose forehand is his best shot, tries to wield that weapon against Wawrinka, who hits his forehand flatter and can be streakier off that side.
Tsonga tends to play closer to the baseline, but both can close at the net and Wawrinka has applied his all-court skills more effectively working with coach and former French Open finalist Magnus Norman. When pushed out of position, both men are prone to indulging their shot-making urges and play the down the line drive.
No. 21 Jerzy Janowicz vs. No. 23 Grigor Dimitrov
What do you get when you mix power, finesse, volatility, agility, eye-popping shot-making on the move and mind-numbing shot selection at crunch time? Magic and mayhem.
You know pop culture has infiltrated the sport when you see two guys with the freaky athletic ability of Janowicz and Dimitrov pull off shotmaking so audacious, it looks like it came straight from the mind of an over-caffeinated video geek on an Xbox binge.
Both men had break-out moments in 2013. In just his fifth Grand Slam main draw, Janowicz reached the Wimbledon semifinal to become the first Polish man to advance to a major semifinal. Dimitrov, who upset world No. 1 Novak Djokovic on clay in Madrid, rallied for a 2-6, 6-3, 6-4 victory over No. 3 David Ferrer in the Stockholm final in October to win his first ATP title, becoming the first Bulgarian in the Open Era to win an ATP crown.
The 6-8- Janowicz looks like he’s leaping off a step ladder when serving -- he hit 30 aces in three sets against Nicolas Almagro at Wimbledon -- but he’s not a mindless baseline basher.
Janowicz’s bold two-handed backhand, flair for the angled drop shot, imposing size and agility, and volatile and wacky temper -- an Australian Open meltdown during which he repeatedly raged "How many times? How many times?" inspired a YouTube hip-hop remix -- make him as unsettling as an evening spent slam-dancing with sumo wrestlers.
Dimitrov is an enchanting talent because he can flash of shot-making magic on the move from virtually anywhere on court, and the contrast between his explosive topspin forehand and the biting slice of his one-handed backhand can be a jarring combination. Dimitrov’s all-court skills and athleticism are dazzling; his atrocious major results -- he’s failed to surpass the second round in 12 of 13 Grand Slam starts -- are disconcerting.
"I think Dimitrov has a huge upside. If he stays healthy, he has a live arm, huge serve, he moves well," James Blake told me last month. "Looks like he's comfortable hitting any shot. Just a matter for him of putting it all together. If I had to say one [young] guy that has the game that actually excites me, it's Dimitrov. Milos Raonic is the most uncomfortable to play, but I don't get quite excited watching a guy serve 25 aces and win a match 6 and 6."
