Trial over for Johansson and Krajinovic

Swede Thomas Johansson signed on to coach Serbia’s Filip Krajinovic last December, on a trial basis.

Krajinovic season started with a two-sets-to-none comeback over No. 18 Marco Cecchinato, a third round in Melbourne, and a win over David Goffin in Montpellier before a squeaker loss to Tomas Berdych (7-6, 6-7, 7-5) in the quarters.

But the trial is apparently over. And Johansson confirms they are done.

Which immediately started the Belgian press speculating about a return to David Goffin, currently coachless. Johansson and Goffin collaborated in 2016.

“We’ll study it, but we haven’t yet contacted him,” Team Goffin told RTBF.

Synergy for Nalbandian and Londero

Argentine players don’t win ATP tournaments in Argentina every day – never mind in their hometown.

In fact, the last time it happened was when former world No. 3 David Nalbandian won the Argentina Open in Buenos Aires in 2008.

But 25-year-old Juan Ignacio Londero did it Sunday in Córdoba. 

In an awesome full circle, Nalbandian and Londero have history together, posing for this pic long before either held up those hometown trophies.

The last player to win his first career ATP Tour match – and win that same tournament – was Steve Darcis in Amersfoort in 2007.

Londero did it last week.

Robson returns in Shrewsbury

Time flies.

Former British prodigy Laura Robson turned … 25 Jan. 21.

And after hip surgery last summer, the former world No. 27 is making yet another injury comeback.

Robson has a wild card into qualifying at the $60,000 ITF in Shrewsbury, England next week. It will be her first singles appearance since May 2018.

She played two doubles matches during the 2018 grass-court warmup season. By Wimbledon, she was ambling around the All-England Club on crutches.

Robson is working with BT Sport on the Fed Cup event from Bath, England this week – so she’ll have to switch gears quickly.

Next week is ATP dropout week

We’re two weeks beyond the first Grand Slam of the season.

But the number of no-shows next week is concerning.

Earlier, Richard Gasquet and Kyle Edmund had pulled out of the 500-level event in Rotterdam with longer-term issues.

Grigor Dimitrov is out with a shoulder problem. So is Alexander Zverev. Nick Kyrgios cited a knee issue.

And Friday, Marin Cilic also sent his regrets, still dealing with a knee issue dating back to last season.

Top seed Kevin Anderson and American Jack Sock pulled out of New York along with Alex de Minaur and Feliciano Lopez.

Notorious Grncarov refunds GoFundMe

Last month, aspiring tennis player Darko Grncarov set up a GoFundMe to finance treatment for an ear issue.

More than $2,000 was raised before Grncarov – who indicated the beneficiary would be actress Karin Duseva – refunded the money. Despite impending deafness.

The campaign remains open; the original target was $5,000.

Grncarov’s troll through social media was chronicled by Slate a year ago.

Still, he has amassed 100,000 followers on Twitter and 80,000 on Instagram – and got verified.

His latest gig is to mobilize his following to get him on the Ellen Show, so she can help him with the ear.

Ana Konjuh back for Fed Cup

Ana Konjuh, a US Open quarterfinalist at 19 and a former junior No. 1 who won the Eddie Herr/Orange Bowl combo and singles and doubles at the Australian Open within two months, is back and playing Fed Cup.

Currently No. 547, Konjuh played her first match since Wimbledon in St. Petersburg last week. She had played just four tournaments since the 2017 US Open, after having elbow surgery for the second time.

Her career high was No. 20, a month before her second surgery.

Konjuh lost to Cagla Buyukackay in three sets Wednesday, but Croatia won its first Euro/African zonal tie 2-1.

DelPo packs ’em in in Tandil

Juan Martin del Potro’s annual open practice back in his hometown of Tandil drew a packed crowd around a couple of modest tennis courts.

The Argentine star twins it with a food drive. And some 730 kilos of non-perishable food were collected for the local food bank.

He did the same thing a year ago – except in December because he was scheduled to start the 2018 season in Australia in Auckland then Melbourne.

This year’s season is only scheduled to start in two weeks at Delray Beach, after he injured his knee in Shanghai last October.

Isner hits the Challenger circuit

It has been nearly a decade since John Isner hit the Challenger circuit.

It was the summer of 2009, when he was just breaking into the top 100. 

He returns next week at the Dallas Challenger, as the tournament announced that Jack Sock was withdrawing due to injury. That’s quite a substitute.

As a top-10 player, Isner (at No. 9) is barred from playing singles in a Challenger per rule 7.07 A (1). 

But doubles is okay. 

He’s teaming up with longtime friend Alex Kuznetsov, who’s been retired for three years and more recently has been the hitting partner of Maria Sharapova.

Tournament director Jérémy Chardy

In keeping with the ongoing theme of tennis conflicts of interest, French player Jérémy Chardy is the tournament director at a new Challenger in Pau, France next month.

Called the Teréga Open Pau-Pyrénées, it’s an $80,000 US event .

As a top 50 player, Chardy can’t technically enter his own tournament. He needs a wild card.

But hey, he’s got a pretty good connection there. 

The 31-year-old won’t have time to be too hands on. He’s entered Montpellier, Rotterdam and Marseille the three weeks leading up to the event.

(Looks like he posed for the ad, though).

Final, final preseason for Ferrer

As David Ferrer says “adios” to the grind of pre-season – on Christmas Day, no less – it sounds like he has no plans to give up tennis.

In a Tweet after a training session at Juan Carlos Ferrero’s Valencia academy, he jokes to Ferrero that he’s “getting in shape to compete with you next year (on the seniors tour)”.

Ferrer will team up with Garbiñe Muguruza at Hopman Cup. And he has a wild card into Auckland.

He’s not in the Australian Open qualifying. but he’s a longshot main-draw alternate. His finale is scheduled for Madrid.
