A-League competition leaders Central Coast will extend their unbeaten streak to 15 matches and Sydney FC are tipped to finally snap their winless skid with online bookmaker sportsbet.com.au installing the Mariners as $1.73 favourites against Adelaide United ($4.30) and the Sky Blues at $1.92 to beat the last placed Gold Coast ($3.60).

“Adelaide will provide stiff competition for the Mariners but they’ve shown they have the players and game plan to go all the way,” sportsbet.com.au’s Ben Hawes said. “And the scary thing for Adelaide is the Mariners are yet to lose at Bluetongue Stadium this season.”

In the remaining Round 16 fixtures, the Brisbane Roar are $2.03 favourites playing away to the Melbourne Heart ($3.20) while little is separating Perth and the Victory ahead of their clash at nib Stadium with the Glory at $2.33 and Jim Magilton’s side a $2.76 chance.

The 2011/12 A-League title looks to be a two-horse race with the Roar and Mariners joint favourites to win the Grand Final at $2.87 while every other team is at $10 or higher.

“It looks like the title race is already down to two but if you think someone else could spring a surprise there is plenty of value to be had,” said Hawes.
