Rodriguez ended on a total of 5,488 after 24 games in total, scoring 1,368 in the singles, 1,377 in the doubles and 1,389 in the trios.

She ended with 1,354 in today's team qualification which was topped by hosts United States at the South Point Bowling Plaza.

"I don't know what to say," said Rodriguez, who has semi-finals to look forward to in both the doubles and trios competitions.

"It is just surreal, it feels great. 

"It has been a long week."

Joline Persson Planefors of Sweden won the silver medal with 5,425 points as American Shannon O'Keefe took bronze on 5,422.

O'Keefe was a member of the American team which won today's team qualification round.

She was joined by Stefanie Johnson, Jordan Richard, Liz Kuhlkin, Danielle McEwan and Missy Parkin as the hosts scored 6,750.

This matched the World Bowling Women's Championship all-time six game record. 

"We played great today and stayed in the moment," said O'Keefe. 

"I don't think anyone ever looked at the scores, we just stayed focused on us. 

"We had no idea about the record, that's pretty awesome."

Mexico, Sweden and Colombia completed the top four with scores of 6,371, 6,353 and 6,341 respectively.
