Auto racing F1 star Fernando Alonso was able to set the fastest time of the day in practice for the season finale, Sunday's Grand Prix of Brazil, with the help of mother nature.

Rain started falling on the second practice session allowing Alonso's time of 1:12.296 to be the best of the day. Ferrari's Felipe Massa was fastest in the first session with a time of 1:12.305 and just slightly slower than Alonso in the afternoon.

In that first session, points F1 leader Lewis Hamilton was second fastest, but was only ninth fastest in the second session.

"Our car was blindingly quick this morning despite the cold weather, which made the track feel quite slippery. This afternoon we focused on our race pace - but we were interrupted by the threat of rain and the changeable wind direction," Hamilton said. "I flat-spotted my tires on a couple of runs, but I'm positive that the changes we've made will put us in a good position for tomorrow."

The drivers have one more practice session before qualifying Saturday. Practice starts at 9 a.m. (ET) with qualifying following at Noon.
