The Scoop: 16 Boys Break 9 Minutes At Arcadia

Oak Ridge (CA) High's Maddy Denner was warming up for her mile effort on Saturday with a robust 3200m performance on Friday on Saturday. 

Making a move relatively early on the field, Denner took control and cruised to the finish in a US No. 8 effort of 10:28.32, just in front of her sister, Elena, who followed in 10:34.56. 

The effort was a primer of sorts for Saturday's invitational sections of the races, which expect to drop some superb times in the boys and girls fields. 

But Denner, naturally, made a good first impression.
