Queenslander, Louis Dobbelaar, has been knocked out in the Round of 64 at the US Amateur, losing his opening round encounter against American Ross Steelman 2 down after being 2 down through 14 when their match was brought to a halt by darkness on Wednesday.

Returning to the Oakmont Country Club on Thursday morning to complete the match, Dobbelaar drew within one hole of Steelman when he birdied the 17th but he would bogey the 18th to lose 2 down.

Steelman would go on to win his afternoon, Round of 32 match, 2&1 and gave an indication of his ability earlier in the week when recording a nine of 30 during a round of 66 in his qualifying rounds.

Dobbelaar was the only one of three Australians in the 300 plus field to advance into the leading 64 who advanced to the match-play phase.
