Perhaps the biggest news of the past week was the sudden retirement of
Novak Djokovic in Dubai. The world No. 1, already down a set to
Feliciano Lopez, quit in the second, citing an eye infection that had plagued him all week.
Djokovic expects to be ready for Indian Wells late next week.
Here's what else was on our writers' minds in the latest edition of Racket Response.
@CarlBialik: The Big Four are idle or ailing. Novak Djokovic has an eye infection,
Roger Federer has delayed a return from knee surgery,
Andy Murray is getting to know his 3-week-old daughter, Sophia, and
Rafael Nadal has failed to reach the final of six of his past eight clay-court tournaments.
With the men who follow the game's elite foundering as well, tennis is ripe for a takeover by youngsters.
Dominic Thiem, a 22-year-old from Austria, is leading the charge -- the same Thiem who beat Nadal at the Argentina Open two weeks ago.
You
haven't heard much from Thiem if you're mostly paying attention to the
Grand Slams. He has reached the fourth round of a major just once.
Perhaps Thiem's shortcomings in majors are because he usually plays the
week before Slams instead of resting and practicing. But in little-known
tour stops in between, Thiem has been thriving.
This past
weekend, he won his second title this month, on Acapulco's hard courts,
his first trophy on a surface on which he hadn't even reached a semi
until last September. Thiem entered the month with one top-10 win -- now
he has three. He is ranked 14th, higher than anyone else under age 25
and closer in ranking points to No. 10 than to No. 15. And he is third
in the race to year-end No. 1.
@ptbodo: Carla Suarez-Navarro
is a human laundry list of all the things you wouldn't want in
contemporary pro player. She's short (5-foot-4) and slightly built, not
particularly fast, and fond of the volley. She plays a one-handed
backhand with frequent use of slice.

Add it all up and
Suarez-Navarro takes on the dimensions of a novelty in today's game. But
it in winning Doha last week, the 27-year-old Canary Islander once
again demonstrated that size, great athleticism and powerful strokes can
be neutralized, and don't always shape the outcome of a match.
Some
thought it a fluke, or certainly a once-in-a-career run, when
Suarez-Navarro won on the red clay at Estoril in 2014 and ultimately
climbed over to tops of all those tall, powerful, baseline bangers to
rank as high as No. 8. But in the interim, she's demonstrated that she's
a top-10 thoroughbred.
Doha represent the second title of her
career, and it was Suarez-Navarro's most impressive performance to date.
She sliced and diced her way through a succession of opponents,
including No. 3 seed
Agnieszka Radwanska. Thanks to the win over rising star
Jelena Ostapenko in final, Suarez-Navarro has shot to a career-high No. 6.
@natkinESPN:
Andy Murray and Great Britain step out as defending Davis Cup champions
Friday, but captain Leon Smith says they're "not here to celebrate."
After
winning the trophy for the first time in 79 years with a victory over
Belgium in November, Britain faces Japan in a first-round tie in
Birmingham, England.
Smith warned against complacency.
"It's
great we've got another home tie," Smith told Press Association Sport.
"We've had a lot of them, but it's great to come out as defending
champions.
"At the same time, we've all been around long enough to
know that it starts again, and we're not here to celebrate; we're here
to win.
"We can enjoy going out there with confidence because we
are defending champions, but we're very much back to business as usual.
We can't underestimate what is a very good Japanese team."
Murray
will lead Britain once more as he returns to the court for the first
time since his Australian Open final defeat to Novak Djokovic and
subsequent birth of the Scot's daughter, Sophia.
@goitiatenis: Now 30 years old,
Pablo Cuevas
of Uruguay has grown into a mature player. He missed two years on the
ATP Tour with injuries, which saw his ranking plummet to below 1,000 by
mid-2013.
Cuevas added two titles to his résumé this season, in
Brazil and Sao Paulo, to take his care total to five, all of them on
clay. At the latter, he successfully defended his crown.
Cuevas
also achieved a rare feat with seven successive victories against
left-handed players -- five in Rio and then two in Sao Paulo.
Beyond
his two titles, Cuevas can also boast of his first victory against clay
master Rafael Nadal. Coached by former top-10 player Alberto Mancini of
Argentina, Cuevas is showing he is now ready to battle successfully
against the elite of tennis.
He
is now No. 25 on tour, the best Latin American, and ready for the next
move: to move into the top 20, something he was very close to achieving
last year.
