LAKE ZURICH, Ill. (WLS) -- Sam Holtz, a Lake Zurich sixth grader, knows how to pick 'em. His NCAA basketball bracket is nearly perfect.
"Just rushed right through it. I think it was all skill, some people say it was luck, but I think I studied enough," Holtz said.
Holtz accurately predicted all four teams in the Final Four. He did such a good job, that with Duke winning, he is tied for first place in ESPN's bracket challenge.
About 11.5 million people filled out brackets this year. There will be a tie-breaking draw for the prizes, which include a $20,000 gift card to Best Buy.
