Okotoks Deb Guelly hits the infield Tuesday at the Calgary Stampede in ladies barrel racing as the second group of competitors take their shot at making it to the weekend.

Guelly, a five time Canadian Champion and a Stampede winner will be in tough though.

Over the first four days, 67 year old Mary Burger from Pauls Valley, Oklahoma has become the "Sweetheart of the Rodeo" as she won all four go-rounds she was in, collecting $22,000 along the way.

She's locked up her spot in the semi-final Saturday, while Guelly is hoping to do the same over the next four days.
