Eight-time Olympic gold medalist Usain Bolt made his first start for the A-League Central Coast Mariners last night in a preseason friendly and left his mark by scoring his first career goal. In fact, the world's fastest man found the back of the net twice.

The Central Coast Mariners, a team in Australia’s top soccer division, defeated Macarthur South West by the final of 4-0. Bolt, playing in a central striking role, scored his first goal in the 55th minute to put Central Coast 3-0 up with a left-footed strike. His second goal came in the 68th minute when he took advantage of a defensive blunder and tapped in an empty-netter.

"Scoring a goal in your first proper match, the first start and scoring two goals, it was a good feeling," Bolt told Fox Sports. "Because this is what I've worked for. I've tried to prove myself -- I've tried to get better. I think I've improved in every area.

"I think my touch is that little bit better. My vision needs to improve a little bit more. I think my running off the ball is where I've improved most."

The A-League season begins next weekend, as Central Coast goes up against Brisbane Roar on Sunday, October 19. Bolt, who started training with the club in mid-August, doesn’t yet have a contract.
