Grigor Dimitrov has hailed the influence of Australian coach Roger Rasheed after lifting the Queen’s Club trophy to triumph on a third different surface this year.

Bulgarian fourth seed Dimitrov saved a match point before defeating Spanish left-hander Feliciano Lopez 6-7 (10-8) 7-6 (7-1) 7-6 (8-6) on Sunday to win grass court tournament and significantly boost his Wimbledon prospects.

In doing so he became the first player this season to win titles on three different surfaces after claiming victories in Acapulco on hard court and Bucharest on clay.

“It definitely shows that I’m capable of achieving even bigger things,” he said of the feat.

All those titles have come since Dimitrov teamed up with Rasheed in October and the 23-year-old believes the Australian’s tough coaching style and focus on fitness has resulted in him taking a more professional approach on all surfaces.

“Just everything happened pretty naturally with Roger,” Dimitrov said.

“I just really needed a strong person on and off the court for me.

“I’m more than happy that most of the times we’re on the same page when it comes to work and practice, so that’s a good sign.”

Dimitrov’s girlfriend, French Open champion Maria Sharapova, was among the spectators at Queen’s and he said she’d also been a positive influence on his career.

“A tremendous champion like her, there is a lot to learn,” Dimitrov said.

In a match that featured few rallies and even fewer break point opportunities, Dimitrov dropped only four points on serve in the first set.

Lopez went on to claim the tiebreaker on his fourth set point and games went comfortably with serve in the second set until the Spaniard held a match point on his opponent’s serve at 6-5.

Dimitrov survived that crisis and then swept the tiebreaker for the loss of just one point, but a forehand volley by Lopez gave the Spaniard a break in the opening game of the final set.

The Bulgarian got back on level terms at 4-4 when Lopez double-faulted, and claimed the tiebreaker on his second match point when Lopez netted a forehand.

Dimitrov said he would head to Wimbledon with “positive vibes” but was thrilled to win a tournament where he was given a wildcard as a raw 18-year-old.

After the win, Dimitrov handed a racquet to former tournament director Chris Kermode, who gave him his first start at Queen’s.

“To me always this tournament has been that tournament I always wanted to win,” he said.

“I remember playing as a teenager here and ever since I have dreamt about that moment.”

Lopez, 32, was attempting to become the oldest winner of the tournament since 33-year old Tony Roche defeated John McEnroe in the 1978 final, and to win his first title since Eastbourne one year ago.
