Andy Murray and Maria Sharapova suffered another day of defeats in the second round of International Premier Tennis League ties in the Philippines.

The pair had lost as a mixed doubles team on day one, and went down again as Manila Mavericks lost to Indian Aces.

Murray and Sharapova were beaten 6-1 by doubles specialists Rohan Bopanna and Sania Mirza, after Murray had earlier lost 6-4 to Gael Monfils in singles.

Ana Ivanovic then beat Sharapova 6-3 as Indian Aces prevailed 24-15 overall.

IPTL teams
Indian Aces (Delhi): Federer, Sampras, Monfils, Ivanovic, Mirza, Bopanna, Santoro
Manila Mavericks: Murray, Tsonga, Flipkens, Nestor, Moya, Sharapova, Huey
Singapore Slammers: Serena Williams, Agassi, Berdych, Hewitt, Kyrgios, Hantuchova, Soares, Rafter
UAE Royals (Dubai): Djokovic, Wozniacki, Cilic, Mladenovic, Ivanisevic, Zimonjic, Jaziri

The four-team event began in Manila on Friday and will move on to Singapore, Delhi and Dubai, with the final on 13 December.

Murray is only scheduled to play over the three days of the Manila leg before the Briton heads to the United States for his annual off-season training block.

Sharapova, the reigning French Open champion, only committed to play the first two days of the inaugural exhibition event.

"This is the first year. Everything is a learning process," said the Russian.

"I felt such a great amount of energy walking out to the court. I really felt the warmth here. I'm very blessed to have good fans who are committed and have followed me through so many years."

Sharapova admitted the 20-second shot clock - one of a number of innovations being used in the team format - was something she had struggled to get used to.

IPTL innovations
Each match consists of five sets: men's singles, women's singles, mixed doubles, men's doubles, legends' singles
The team that wins the most games, accumulated from all five sets, wins the match
Each set is played first to six games with a five-minute shoot-out at 5-5
Players have a 20-second shot clock between points
Team coaches can call a 60-second time-out once during each set
The receiving player can call a Power Point once every set, indicating that the next point counts double

"I feel like pressing 'snooze' all the time," she said of the loud beeping that warns players if they are getting close to the time limit.

Murray will complete his IPTL stint on Sunday when Manila take on Singapore Slammers, with Tomas Berdych due to face the Scot in singles.
