LAS VEGAS (AP) — Kyle Busch is in a terrible slump and winless this Cup season.
His 15-year streak of at least one victory a year in danger.
The reigning Cup champion struggled to contain his frustration after finishing second last week at Bristol to title favorite Kevin Harvick and his losing streak was extended to 29 races.
Busch predicted his bid to win back-to-back titles will soon be over.
The second round of the playoffs begins Sunday at Las Vegas Motor Speedway in the city where Busch grew up.
