Martin fastest in Kobalt Tolls 500 Happy Hour

Mark Martin posted the single fastest lap in Happy Hour practice for the Kobalt Tools 500 with a speed of 185.524 mph.

Our View Races aren't won on a single lap, however, and his average speed of 178.074 during 45 laps was well down the chart. Moreover, last year Martin finished 31st in this race but was in top form during the fall with a fifth.

This weekend could go either way for the veteran.
