Unlike the 450 class, which is all but wrapped up with Cooper Webb’s massive lead, the Supercross 250s have much tighter battles on the line and both championships will be decided this week in Las Vegas during the second East/West Showdown of the year.
In the West, Adam Cianciarulo holds an eight-point advantage over Dylan Ferrandis.
In the East, Chase Sexton has an advantage of nine points over Justin Cooper.
In both, it’s a two man battle, but since this is an East/West Showdown with both divisions on track at the same time, there will be four riders to watch Saturday night.
Cianciarulo’s magic number is fifth. If he finishes there or better, it’s Cianciarulo’s title no matter what Ferrandis does. In the last East/West Showdown at Atlanta, Cianciarulo and Ferrandis finished first and second.
Cianciarulo got where he is by winning five races and sweeping the top five. Ferrandis has two wins and five runner-up finishes, but he lost significant ground in Glendale during Round 2 and in the mud at San Diego three weeks later when he finished outside the top five.
Sexton’s safety valve is sixth or better. Even if Cooper wins and ties Sexton with one win apiece, Sexton has three second-place finishes to Cooper’s one and so he holds the tiebreaker.
With the dominance of Austin Forkner, Sexton has been the forgotten man. He finished fourth in the last Showdown at Atlanta, but that was one of only two times that he failed to stand on the podium. A sixth-place finish is not a foregone conclusion, but one would be hard-pressed to bet against Sexton.
Like Sexton, Cooper has a perfect record of top-fives but his average finish lags behind Sexton has an average of 2.75; Cooper’s is 3.25.
With two division on track, finishing among the top six is not a foregone conclusion. Eat coast rider Mitchell Oldenburg has three top-fives in his last four starts including a second last week in New Jersey. Colt Nichols has third-place finishes in his last two attempts and he won the season opener in Anaheim.
