When dark clouds ominously obscured majestic Mount Baldy north of Auto Club Speedway early in Sunday's race, NASCAR's drivers all realized they were probably in for a short day on a long track.

Nobody did a better job racing until the raindrops fell than Tony Stewart.

Stewart got his second NASCAR victory of the season when rain shortened the race at Auto Club Speedway by 71 laps, extending the defending Sprint Cup champion's unusually strong start.
