ＬＡでゴルフコミュのトーナメント・ルール？

英語とゴルフのルールが解る方教えてください。

先週末宮里藍選手が今年５回目のＬＰＧＡ大会（Safeway Classic@Pumpkin Ridge, Oregon)優勝された試合での出来事。
ＬＰＧＡ試合途中、ベテラン・プロのインクスター選手が１０番ホールのティー場で待っている合間の３０分、重りがついた練習器具をアイアンにハメつけて使いスウィングし時間つぶし（本人の説明だと筋肉をほごしいた）その結果：１８番ホールを終了後トーナメント・オフィシャルから彼女にＤＱ（ルール違反）と通告された。彼女は最終日の出場もＮＧとなった。

トーナメント試合の時はそういった練習器具を使ってはならないみたいですね（どのな小さな物でも）？

Inkster disqualified due to use of training aid

Posted: August 21, 2010
NORTH PLAINS, Ore. – Juli Inkster was disqualified from the LPGA Safeway Classic for using a weighted training aid on her club while waiting on the No. 10 hole on the Ghost Creek Course.

After the 50-year-old Hall of Famer finished her round and was told of the disqualification, Inkster passed quickly by autograph seekers and reporters without comment. She quickly left in a course shuttle.

It was heartbreaking for Inkster, who shot a 67 and was 8 under after the first two rounds. She was in a group just three strokes behind leader Ai Miyazato.

Inkster, who had a 30 minute wait for the No. 10 hole, apparently used a “doughnut” weight on her 9-iron to stay loose.

LPGA Director of Tournament Competitions Sue Witters said a viewer noticed the device from the television broadcast of the event and contacted tournament officials.

Inkster was already on the 17th hole of the course at Pumpkin Ridge when officials determined she had indeed used the device. She was told when she came off the course after the final hole, Witters said.

Witters said Inkster was surprised and unaware she had broken the rule.

“The rules staff here made the decision on the rule and we took it one step further and called the USGA,” Witters said. “We would have loved to have some wiggle room on that. But it’s pretty cut and dried.

“Being the professional she is, there wasn’t much to say once the decision was read.”

Inkster issued a brief statement.

“I had a 30-minute wait and I needed to loosen up,” she said. “It had no effect on my game whatsoever, but it is what it is. I’m very disappointed.”
