Roddick through after early scare

Andy Roddick recovered from an epic first set tie-break setback to overcome spirited Jo-Wilfried Tsonga to book his place in the second round of the Australian Open.

The sixth seed lost a record equalling tie-break 20-18 and looked to be heading for defeat in the second as Tsonga served for a 2-0 advantage at 5-2 but the American recovered to level the tie.
