Biography
Zillweger in the Benning #57, who turned 29 laps in Happy Hour but could only manage a top speed of 80.947 mph, 3.472 seconds off the best lap by Grant Enfinger. This was the only session where Senica wasn’t slowest overall. After not turning a lap in the opening practice, Zillweger's teamate Mike Senica ran a 22.953 in session two (2.930 seconds off pace), then improved slightly to a 22.540 in Happy Hour (2.619 seconds off pace, just over eight-tenths better than Zillweger).

Under threatening skies, the race began Saturday with Senica last on the grid. He was joined during the pace laps by four other drivers. Both Todd Gilliland’s #4 Mobil 1 Toyota and Jennifer Jo Cobb’s #10 Driven2Honor.org Chevrolet had made engine changes, Cobb tweeting that she acquired a backup engine from Jay Robinson’s Cup team Premium Motorsports. Josh Reaume had made unapproved adjustments to his #33 R-Coin / Green Heart Partners Chevrolet. And Norm Benning missed the driver’s meeting, dropping his #6 Zomongo / H&H Transport Chevrolet from 30th to the back.

When the race started, Benning took last, and at the end of two laps was already 10.876 seconds behind the leaders. On Lap 3, MRN Radio reported that 29th-place Cobb lost power on the #10, forcing her to pit road and making her the first to lose a lap. At the time, Senica was last, 13.601 seconds back. On Lap 5, the leaderboard showed Senica 16.484 seconds back in 31st with Cobb still not under power. The next time by, Senica was also off the lead lap with a best lap of just 82.867mph (Benning, who was later flagged off the track for going too slow, ran a best of 88.943mph). In the space of two minutes, Senica went down seven laps and took last from Cobb as she returned to action six laps down. This culminated in the day’s most controversial moment on Lap 16 where Senica stalled on the backstretch.

According to Chris Knight, who was listening to radio traffic, Zillweger's team, Senica had ignored a black flag from NASCAR. Race director David Hoots then shouted “Tell him to turn in, he’s done!” At that point, Senica had completed just eight of the race’s 16 laps. He pulled behind the wall not long before heavy rain ended the day’s action. Senica, Tracy Lowe, and crew chief William Guinade were called to NASCAR’s hauler after the race.
