Will Power shook off a six-month layoff by pacing the opening practice of the IndyCar season.

The defending series champion wasted no time shooting to the top of the leaderboard as he weaved through the streets of St. Petersburg, site of Sunday's season-opening race.

Power's title run began on this 1.8-mile, 14-turn temporary street circuit with a win in last year's opener.

It was the first of three wins for the Australian, who finally broke through with his first series championship after losing three consecutive titles from 2010 through 2012.

Now that he has his crown, Power is determined not to let up one bit.
