The DBS Singapore Slammers went down 21-29 to the Manila Mavericks on Tuesday night, the opening day of the local leg of the Coca-Cola International Premier Tennis League (IPTL).

Despite a line-up that included former men's world No. 1 Andre Agassi and world No. 1 women's player Serena Williams, the home team was able to post just one win out of five matches.

Williams beat Belgium's Kirsten Flipkens 6-5 after a hard-fought match, but the Slammers were unable to outplay their opponents in the other matches, despite their opponents fielding a side that was missing star players Andy Murray and Maria Sharapova.

In the men's legends singles, Agassi was beaten 6-3 by Australia's Mark Philippoussis, while Tomas Berdych and Lleyton Hewitt were defeated 6-4 by Treat Huey and Jo-Wilfried Tsonga in the men's doubles.

Berdych was also beaten 6-5 in the men's singles by Tsonga. Williams, teaming up with Australian Nick Kyrgios in the mixed doubles, was also unable to get past Flipkens and Daniel Nestor. They were defeated 6-3.

This means the Slammers are still winless after four ties so far in the IPTL, and lie bottom of the four-team standings with six points. They play top-ranked Micromax Indian Aces on Wednesday.
