After six days of sunny snowboarding, the Sprint U.S. Snowboarding Grand Prix closed up shop at Mammoth Mountain on Sunday with Jamie Anderson (South Lake Tahoe, CA) winning the Paul Mitchell Progression Session.

Under bluebird skies and balmy temperatures, Anderson led the women followed by Isabelle Lalive (Breckenridge, CO) in second and Molly Wilson (Basalt, CO) third.

Anderson threw out a frontside 3, back 180, tailpress to a 270 out of the box, ollie onto the down rail, indie over the step down, frontside 7 off the last kicker.

For Anderson, being able to throw a 7 was a huge step forward in her progression.

"I'm so happy. I don't usually do 7s. I've been working on them, but they're not one of my consistent tricks. So I was proud of myself to actually step it up and try because it wasn't a guarantee that I was going to land," Anderson said. "I was risking it. The first one I kind of fell on, but the second one I stomped, so I'm pumped."

After landing her second set solidly, Anderson is ready to take on the rest of the season with a new level of confidence.

"I definitely want to step up my game and do bigger tricks at all the events this winter with X Games and the Dew Tours," Anderson said. "Knowing that I have this trick dialed is a really good feeling.

"

Anderson now plans to fine tune her slope skills at the Winter Dew Tour, which will be held Jan. 14-17 at Snowbasin resort in Utah.

As for the Grand Prix, it takes a little break prior to the two event finale at Park City Mountain Resort Jan. 22-23.
