Bob Bryan and Mike Bryan have triumphed at the Delray Beach Open by VITACOST.com four times, and on Sunday, they’ll have a chance to make it five titles at the ATP 250 event.

The twins on Saturday afternoon defeated Marcelo Arevalo and Jamie Cerretani 6-3, 7-5 in 70 minutes, giving themselves a chance to lift their 117th tour-level trophy as a team. This is their first championship match since Bob underwent a right hip replacement surgery last August.

“I didn’t know if I was going to be in a position to hold up another professional trophy. I was happy when I played my first professional match back from the surgery, so this is a bonus,” Bob said. “We don’t take this for granted. We know this is the last chapter of our career and we’re just going to try to enjoy it as much as we can.”

The Americans enjoyed almost immediate success upon their return, advancing to the Australian Open quarter-finals. Bryan/Bryan lost to eventual champions Pierre-Hugues Herbert and Nicolas Mahut in Melbourne, but it did not take long for them to find their groove.

“It came pretty quickly. When you have 40 years of experience, it comes back pretty quickly. We had three weeks together in December when we played a bunch of practice matches,” Mike said. “It was basically just filling in the holes, and he just needed to move better, which he started doing in Australia. Then it’s just handling the pressure again together and that’s what you need to do after a long break, just play those big matches.”

Fittingly, Arevalo/Cerretani was one of the teams that the brothers practised with in December. Bryan/Bryan did not face break point in their semi-final, breaking Arevalo/Cerretani twice to advance to the final. On Sunday, Bryan/Bryan will face Ken Skupski and Neal Skupski (not twins) or singles semi-finalist Radu Albot and Yoshihito Nishioka.

Mikhail Kukushkin reached his first tour-level championship match in more than four years on Saturday, ending the run of French wildcard Ugo Humbert 6-4, 6-4 at the Open 13 Provence.

The 31-year-old Kazakh, who reached his third ATP Tour final at the 2015 Sydney International (l. to Troicki), advanced to the championship match after one hour and 33 minutes, winning 83 per cent of service points (38/46) en route to victory. Kukushkin will be aiming to capture his second tour-level crown in Sunday’s final, more than eight years after claiming his maiden title at the 2010 St. Petersburg Open (d. Youzhny).

Kukushkin will meet top seed Stefanos Tsitsipas or third-seeded David Goffin for the title. The World No. 50 trails Tsitsipas 0-1 in their FedEx ATP Head2Head series and also lost his only previous FedEx ATP Head2Head encounter against Goffin.

After failing to convert five break points in a marathon opening game, Kukushkin earned the only break of the first set at 1-1 with a dipping cross-court forehand passing shot. The Kazakh, who won each of his 20 service points in the opening set, continued to apply pressure to Humbert’s serve in the second set, breaking at 2-2 with great court coverage. After dropping serve at 4-3, Kukushkin won back-to-back games, booking his place in the final with a well-placed backhand lob.

Appearing in his first ATP Tour semi-final, Humbert was aiming to add to a strong tradition of French finalists in Marseille. Since 2006, the home nation has had at least one representative in 10 of the past 13 singles finals.

All four semi-finalists at the Open 13 Provence reached the last four without dropping a set.

Chasing his 100th tour-level title, Roger Federer will begin his quest for a record eighth Dubai Duty Free Tennis Championships title against Philipp Kohlschreiber.

The seven-time champion, who most recently lifted the trophy in 2015 (d. Djokovic), will be making his first tour-level appearance since falling to Stefanos Tsitsipas in the Australian Open fourth round last month. With a perfect 13-0 FedEx ATP Head2Head series record against Kohlschreiber, Federer will be aiming to improve to 13-1 in first-round matches at the ATP 500 event. Andy Murray is the only man to have beaten the 99-time tour-level titlist in the first round, having defeated Federer in three sets in 2008.

If Federer comes through his opening match against Kohlschreiber, the Swiss could potentially face Fernando Verdasco in the second round. Federer shares the bottom quarter of the draw with seventh-seeded Canadian Milos Raonic, who has opened his 2019 campaign with seven wins from 10 matches. The former World No. 3 reached back-to-back quarter-finals in Brisbane and at the Australian Open, before a second-round loss to eventual runner-up Stan Wawrinka in Rotterdam.

Karen Khachanov and Borna Coric will both feature in the same half of the draw as Federer. Khachanov, who opens against Nikoloz Basilashvili, will be eager to return to winning ways after back-to-back opening-match losses in Sofia (l. to Berrettini) and Rotterdam (l. to Griekspoor). After suffering a second-round defeat to Ugo Humbert in Marseille, Coric will be bidding to reach his third quarter-final in four appearances in Dubai.

In the top half, No. 1 seed Kei Nishikori will be aiming to extend his winning streak against Benoit Paire to four matches. The Dubai debutant owns a 5-2 FedEx ATP Head2Head record against Paire and will be hoping to continue his strong start to the season. Nishikori has reached the quarter-finals or better in each of his three tournament outings this year, which includes his title run at the Brisbane International (d. Medvedev) last month. Nishikori is joined in the top quarter of the draw by Australian Open semi-finalist Tsitsipas, who is aiming to lift his second ATP Tour title this week in Marseille.

Two-time Dubai quarter-finalist Marin Cilic will return to the event for the first time since 2010. The third seed faces a tough opener against recently-crowned Rotterdam champion Gael Monfils. The in-form Frenchman is unbeaten in three FedEx ATP Head2Head encounters against Cilic.

Eighth seed Daniil Medvedev could meet the winner of that match in the quarter-finals. The 23-year-old Russian opens against a qualifier, with a potential second-round clash against Sofia semi-finalist Matteo Berrettini or Denis Kudla.

Although Juan Martin del Potro wasn’t pleased with his quarter-final loss on Friday against Mackenzie McDonald at the Delray Beach Open by VITACOST.com, the Argentine is taking the positives from the week.

Del Potro returned to action after sitting out four months with a right knee injury. He visibly struggled with the knee against McDonald, but showed plenty of heart in extending the match to a third-set tie-break. The Argentine has always been methodical in his comeback attempts, returning only when he’s ready instead of rushing back too soon, but admitted the desire for matches is as strong as ever.

“The doctors say I need time if I want to be 100 per cent, but I don’t want to be home watching the tournaments on TV. I’ve done that before and it was really bad for me,” he said. “I wanted to do a big effort tonight. I fought until the last ball and had many opportunities, but it’s hard to win matches when you can’t move at 100 per cent.”

The good news for del Potro is that while his lateral movement understandably let him down against McDonald, his tennis did not. He held in 15 of 16 service games and racked up 16 aces. When he was in position to strike his forehand, he produced plenty of vintage winners.

Having secured two straight-sets wins this week, including a second-round victory over New York Open champion Reilly Opelka, the Argentine has plenty to build on.

“I played three matches after four months away and that’s the best thing for me,” he said. “I know how good I can be when I’m ready, but I’m not in the physical condition to play at this level yet.”

One thing that never wavered is the support for the always-popular Argentine. Even against an American opponent, the Delray Beach crowd urged the top seed on against McDonald by chanting “Delpo” between points and on changeovers.

Del Potro has always fed off the energy of a packed stadium, but it could be even more crucial for him as he continues his efforts to return to full strength.

“I have a lot of respect for my fans who paid for a ticket and came to watch me play. I know they understand if I can’t play, but I wanted to try and think I did a good effort,” he said. “I wanted to play because this is the reason I came to Delray Beach. The final score doesn’t matter to me.”
