It's been a fantastic year: Rohan Bopanna

London: Following their loss in the title round of the year-ending $7 million ATP World Tour Finals at The O2 Arena here, top Indian tennis player Rohan Bopanna has said 2015 has been a fantastic year for him and his men's doubles partner Florin Mergea of Romania.

Second seeds Horia Tecau and Jean-Julien Rojer defeated eighth seeds Bopanna and Mergea 6-4, 6-3 on Sunday evening for their 11th team title, and third of the year that includes their maiden Grand Slam at Wimbledon.

"It was just a tough day today. But it's been a great week, making it to the final, first-time outing for us as a team," said the 35-year-old Bopanna after the loss.

"And for the season, starting out in April, playing just about a handful of tournaments and to qualify here, I think it's been a fantastic year for us. We can take a lot of positives from this year, and we are looking forward to starting fresh in January."

Bopanna and Mergea first teamed up at Casablanca in April and end the year with a 31-16 record, including two titles from four finals.

Mergea added: "It's a pleasure to play in the World Tour Finals title match. Obviously, this has been the first time two Romanians (Tecau being the other) played the doubles final here. I think it's an historic day for us."

Bopanna ends the year as World No.9, having won four titles -- two with Mergea in Madrid and Stuttgart and two with Daniel Nestor in Dubai and Sydney, making 2015 the most successful season of his career.
