Grigor Dimitrov continues to soar in 2017 having booked a quarter-final place at the ABN AMRO World Tennis Tournament with a 7-6(7), 6-1 win over Denis Istomin on Thursday.

Dimitrov, now holding a 16-1 match record this season, continued his impeccable recent form to instantly break the world No.76. However, Istomin duelled in a series of entertaining rallies to force a tie-break. The duo finished the set on 50 points apiece, but with 18 winners and 11/13 successful net points, the Bulgarian went ahead after Istomin’s only double fault.

A pair of forehand winners secured a 3-0 advantage for the 25 year old and some outstanding retrieval play built on that lead to secure his third straight victory over the Uzbekistani.

World No. 12 Dimitrov will face David Goffin, whom he defeated in the final of the Garanti Koza Sofia Open on home soil last week, for a first Rotterdam semi-final since 2013.

Kei Nishikori’s connection to Argentina goes way beyond his partnership with current coach Dante Bottini. More than a decade after winning the 2006 Roland Garros boys’ doubles title, Kei Nishikori and former Argentine player Emiliano Massa reunited at the Argentina Open in Buenos Aires.

After Nishikori defeated Diego Schwartzman in his opening match on Wednesday, he met up with Massa in the player’s lounge to relive those special memories. What they lacked in verbal communication during their junior playing days, they made up for with a natural partnership on court.

“We almost lost the first two matches. We barely spoke English at the time, so we talked very little to each other,” recalled Massa to the Argentina Open website. “What I remember most is his speed. Not only his movements, but also the acceleration.”

Their careers ultimately went in radically different directions. Massa was forced to retire from competitive tennis at age 23 due to injuries, while Nishikori went on to become a Top 10 fixture and global superstar. But the Argentine showed nothing but happiness for his former doubles partner and even took a picture with Nishikori to remember their reunion.

“I have the greatest memories with him from my junior years. It was the first time I won a Grand Slam and it was a very special moment for us,” said Nishikori. “Emiliano is an extremely nice guy. It’s been almost 10 years since we had seen each other and unfortunately he had so many injuries. [But] it’s been great to see him. All the memories came back.”
