MELBOURNE, Australia — U.S. tennis star Bob Bryan was facing a race against time Saturday to return to Miami for the impending birth of his first child.

But he will be traveling back home from the Australian Open without a record 12th men's doubles title.

He and his twin brother, Mike Bryan, fell in straight sets to Leander Paes and Radek Stepanek in the final Saturday, the same day that the father to be's wife originally was expected to deliver a baby girl.

But Bob Bryan confirmed postmatch that the due date was likely to be pushed back a little.

"She's probably going to deliver Sunday, so thanks baby, thanks for holding it in for me," he said.

The status of his wife's labor became an international talking point after it emerged that she was forced to switch off the TV coverage of her husband's gripping semifinal because of contractions felt amid the excitement.

She missed the two brothers deliver a stunning win after a final-set tie-break decider, but the pair fell short on the brink of history in Saturday's final.

A win would have seen the Bryans surpass Australian greats Todd Woodbridge and Mark Woodforde in the men's double grand slam listings, whose partnership also generated 11 titles.

But the Indian-Czech pairing of Paes and Stepanek came out 7-6 (7/1) 6-2 victors to deny the Americans at Melbourne Park.
