MARCOS Ambrose scored his second NASCAR Sprint Cup victory yesterday in front of his family as the Watkins Glen race ended in chaos with oil on the track.
The Launceston-born driver was defending his 2011 Watkins Glen title.
Yesterday, Ambrose grabbed victory in his number 9 Stanley Ford on the last corner of the last lap as oil on the track saw the lead cars slipping and sliding across the track.
Ambrose said it was great to have his family at the track to see the win.
``That's why I've got them up here because they haven't ever shared this.
``My kids haven't shared this in America and its a special thing to win a NASCAR race, especially a Sprint Cup race, so its fantastic.''
Ambrose told the post-race media conference that the race was ``absolutely chaos at the end'' with the three lead cars very evenly matched.
``It was great racing with Kyle (Busch) and Brad (Keselowski), and that's the way racing should be,'' Ambrose said.
``I couldn't figure out where it (the oil) was coming from. It was just absolutely crazy at the end.''
Ambrose said he thought he was going to finish in second place after Busch went spinning off the track but he managed to pass Keselowski on the last corner and power to the chequered flag.
Both cars ran on to the grass verges of the track as they fought for the lead.
``It's just a real thrill to be back in Victory Lane. We earned it. We were up there with the big boys and led a lot of laps today and we had to pass a lot of cars to get the win and we did it,'' Ambrose said.
The win lifted the lead Richard Petty Motorsports driver to 17th in the NASCAR standings and put him in contention for a wildcard entry into the championship-ending Chase for the Sprint Cup.
It also guarantees him a start in the 2013 Sprint All-Star race.
Ambrose, the 2003-2004 Australian V8 Supercar champion, is only the fourth non- American driver to win a Sprint Cup race.
His second Watkins Glen win will boost his reputation as one of the best road course drivers in the premier US motor sport competition, which is run mainly on oval tracks.
Ambrose now has two wins and four top-three finishes at the New York state track since starting his NASCAR career in 2006.
