Kyle Larson still feels NASCAR championship pressure despite comfortable lead for Homestead finale

A lap down and mired in heavy traffic outside the top 20 during Sunday’s NASCAR race at Martinsville Speedway, Kyle Larson glanced at a large infield video monitor.A graphic on the screen indicated his comfortable Chase points lead was in danger of being chopped in half.That sobering image lingered in Larson’s mind even after rallying for a ninth place that put him on a glide path entering the season finale at Homestead-Miami Speedway, where he could become the first back-to-back Cup Series champion since Jimmie Johnson (who won five consecutive titles from 2006-10).“It’s not locked up, so there’s still definitely pressure,” Larson said. “I don’t know if I should feel pressure, but I’m going to throughout the week. These races can get crazy. Something can happen that you don’t get to score the points you need.”With a 67-point lead on Christopher Bell, Larson won’t need to do much at Homestead, and he has excelled at the 1.5-mile oval in South Florida with two victories in the past four
