SATURDAY, JUNE 30
Don't Miss: BMX Vert (ESPN3, 8:30 p.m. ET). Vert legend Jamie Bestwick is on arguably the most dominant run in X Games history, winning the past five gold medals, including his most recent at age 40. But to complete just the second six-peat in any XG discipline, the affable Briton will have to hold off 2011 silver medalist Steve McCann of Australia, who has rapidly closed the gap in the past year. Bestwick still holds a sizable advantage in the height he reaches out of the pipe, but McCann's triple tailwhip and no-handed 900 last year showed he's technically on par with Bestwick, if not superior, as some insiders believe. Will Bestwick unveil his most technical tricks to confirm his untouchable reputation, or will McCann break one of the great streaks in BMX history? Their showdown -- which could also feature Vince Byron and Chad Kagy -- promises to be one of the highlights on a whirlwind day in L.A.Also: Rallycross racer Tanner Foust and Hollywood stunt driver Greg Tracy will be turning X Games upside down in the Hot Wheels Double Loop Dare (ABC, 1 p.m. ET), the follow-up to Foust's world-record setting Hot Wheels for Real jump last year at the Indianapolis 500. ...

Vicki Golden defends her Women's Moto X Racing gold against the likes of Tarah Gieger and Meghan Ruttledge (ESPN3 8 p.m.; ESPN 9 p.m. ET). ... With Shaun White officially out of the picture, Pierre Luc-Gagnon shifts his focus to rising Skate Vert challengers, including Alex Perelson and Mitchie Brusco (ESPN 9 p.m. ET). And Nate Adams is the man to beat in Moto X Speed & Style, an event combining racing chops with freestyle flair.
