Singapore: American legend Andre Agassi said he was embarrassed at his International Premier Tennis League cameo on Thursday after he was left out of the final night of action in Singapore.

The eight-time Grand Slam champion was reduced to watching from the sidelines as his Singapore Slammers team-mates, including Serena Williams and Tomas Berdych, beat the UAE Royals 27-25. Agassi lost 6-3 to Mark Philippoussis on Tuesday and 6-2 to Fabrice Santoro on Wednesday, and was replaced by Pat Rafter for Thursday's legends match against Goran Ivanisevic.
