Blue Square have odds on Clijsters that are shorter than those of Serena Williams.

Kim Clijsters is now the favorite with Blue Square to win the Australian Open as her odds to win that title for the quickly approaching Grand Slam are now shorter than the odds of defending champion Serena Williams.

Williams' price is +300 (3/1) while Clijsters, who defeated Williams at the US Open, is at +275 (11/4).

The shortening of Clijsters' price comes on the heels of her title in Brisbane where she defeated Justine Henin is a closely contested final.

Clijsters is also a fan favorite with the Australian public as she gained popularity down under despite not being an Aussie, partly due to her relationship in the past with Australian Lleyton Hewitt.

You can still get a valuable price on Clijsters with Players Only, a site that typically specializes in North American sports betting lines as opposed to tennis.

They have Clijsters priced at +400 (4/1) still, a line that has to be considered a steal at this point.
