SciAps sponsoring Ryan Sieg for full 2025 Xfinity season

SciAps will return to sponsor Ryan Sieg for the duration of the 2025 Xfinity Series season, he announced on Tuesday.

Sieg is coming off a 2024 season in which he narrowly missed the Playoffs, while tallying four top-five finishes, the same amount he had over the previous three seasons combined. He was in position to win intermediate races at Texas Motor Speedway and Las Vegas Motor Speedway, but finished runner-up each time.

Matt Noyce will return as crew chief of the No. 39 car for a second straight season. The team will continue to have an alliance with Haas Factory Team.
