What won the race: Denying Dave Mass his first series victory, fourth-starting Shane Sabraski of Rice, Minn., blew past Mass on the backstretch on the 31st lap and led the rest of Friday's 40-lap Structural Buildings WISSOTA Challenge Series feature at Fiesta City Speedway. Mass built a two-second lead by halfway after overtaking Jeff Provinzino on the fourth lap, but he couldn't repel Sabraski's second-half charge in the low groove that paid $3,000.

Quotable: "I just kept working the bottom there coming off of turn two, and I knew there was good traction down there, but it didn't seem like I was gaining anything on them for a while and then all of a sudden I seemed like I was, so it must have been cleaning up," Sabraski said. "I know I got to him a couple of times and I honestly just wanted to wait until I could make the pass clean before he seen me, so it was awesome."

Key notes: After the race, eighth-place finisher Cole Searing headed for a local hospital and was diagnosed with appendicitis and had a ruptured appendex removed Saturday morning; WCS series regulars voted unanimously to grant Searing hardship points for the weekend's remaining series events at Madison (Minn.) Speedway and Casino Speedway in Watertown, S.D. ... At Fiesta City, Sabraski, a second-year Late Model driver with more than 950 victories in WISSOTA-sanctioned divisions, scored his first WCS victory of the season and fifth of his career. ... He lapped all but eight competitors. ... Sabraski's victory lifts him to reclaim the early season points lead. ... Dave Mass posted his second straight series runner-up finish. ... Jeff Provinzino led the first three laps and was running second when he broke a driveshaft on the seventh lap and required a push to the pits (fifth-running Joel Bennett pitted during the caution period and never returned). ... Besides the yellow flag for Provinzino, two other cautions slowed the 40-lapper, including on the lap-seven restart when Jon Tollakson, John Kaanta and Morgan Ward Grosz got tangled up. ... Gunner Frank drew a lap-eight caution. ... Kyle Jensen scratched from the feature. ... During pace laps, the track ran in missing man formation in honor of a track worker Dave Feldhake, who died in September from thyroid cancer. He handled track surface prep. ...
