Defending champions Indian Aces suffered their first loss in the second edition of the International Premier Tennis League (IPTL), going down 24-25 to Philippine Mavericks in a thrilling contest on Tuesday.
 In a contest that went down to the wire, the Mavericks showed better nerves at the crucial moments and ended on a high when Serbian Milos Raonic won the fifth set after a monumental fight with Spain's Rafeal Nadal.
The Indian Aces found the going tough initially with France's Fabrice Santoro failing to overcome Australian Mark Philippoussis, losing the 31-minute duel 6-4 in the men's legends singles.
In the men's doubles, Ivan Dodig and Nadal brought the Aces back into the contest with a 6-4 victory over the combination of Richard Gasquet and Edouard Roger-Vasselin.
Indian pair of Rohan Bopanna and Sania Mirza gave the Aces a 2-1 lead when they sent the Filipino-American duo of Treat Huey and Serena Williams packing with a 6-3 win in the mixed doubles competition, which lasted 22 minutes.
Trailing after three sets, the Mavericks then relied on multiple-time Grand Slam winner, Serena Williams to get them back into the contest.
Serena showed once again why she is the top women's singles player in the world as the American took 25 minutes to register a resounding 6-3 win over Australian Samantha Stosur.
With the scores levelled, Nadal took the court against Raonic but the nine-time French Open champion failed to get his side across the line.
After a 37-minute battle, Raonic edged out Nadal 6-5 (7-6) in the decider as the Aces ended the Manila leg on a disappointing note.
Earlier, the UAE Royals defeated Singapore Slammers 26-23 in the first encounter of the day.
