Red Bull's Mark Webber made the most of the conditions to post the fastest time before heavy rain returned to mar the second practice for the Belgian Grand Prix on Friday. The Australian clocked 1 minute, 50.321 seconds, with Ferrari's Fernando Alonso second-quickest in 1:50.461, and McLaren's Jenson Button third in 1:50.770. Heavy rain affected the first practice, and another big downpour arrived nearly one hour into the second session. "We got some dry running in, but only around four laps, two laps on the soft tire and two on the medium," Webber said. "We need to get out there and get the mileage in, but on the other side of the coin we need to save tires for Saturday and Sunday. The curbs are the hardest thing here when it's wet, it makes the white lines like ice." Defending F1 champion Sebastian Vettel was only 10th-fastest, but took no risks in the treacherous conditions.
