Monday Motorsports: McLaren's Button and Hamilton Put Red Bull on Notice With the opening race of the 2012 Formula One season, the McLaren Mercedes MP4-27 proved it wasn't just a pretty face. The step-nosed competition hunted for a route around Jenson Button, racing in the lithe, sensuous McLaren car, but even the Red Bull driver Sebastian Vettel, the 2010 and 2011 Formula One champion, could not find a clear line of attack. Button beat his teammate Lewis Hamilton, the pole sitter for Sunday's Australian Grand Prix, off the start, and never relinquished his lead over the 58-lap contest. Though Hamilton held second position for much of the race ahead of Vettel, he fell back after a restart precipitated by Vitaly Petrov, the Caterham driver, whose car stopped in the middle of the track, drawing a caution and bringing out the safety car. On the restart, Vettel stayed on the track while Hamilton pitted, giving the Red Bull driver second position behind Button. Button, the 2009 champion, withstood Vettel's attack, ultimately crossing the finish line 2.1 seconds ahead of the 24-year-old German. Hamilton finished third, giving McLaren two podium finishes. Mark Webber, the Red Bull No. 2, finished in fourth ahead of Fernando Alonso of Ferrari. Kimi Raikkonen, returning to the series after competing in the World Rally Championship and dabbling in the Nascar Camping World Truck Series, finished seventh behind Kamui Kobayashi. The Malaysian Grand Prix is scheduled for Sunday. Here are other motorsports results from the weekend: At the 12 Hours of Sebring, the season opener for the American Le Mans Series, there were few surprises, with the Audi R18s claiming the top two finishes in the LMP1 class, followed by a Honda Performance Development prototype. The winning Audi team consisted of Allan McNish, Dindo Capello and Tom Kristensen; it was Kristensen's sixth victory at Sebring. Brad Keselowski dominated the Sprint Cup field Sunday at Bristol Motor Speedway in Bristol, Tenn. A late restart after the 2011 Sprint Cup champion Tony Stewart made contact with the outer wall threatened to erase Keselowski's lead, but he managed to beat Matt Kenseth around the first corner and maintained his advantage for the win. Keselowski races for Penske, which recently announced it would switch from Dodge to Ford in 2013. Held during Daytona Bike Week, the Daytona 200 A.M.A. Pro Sportbike race was won on Saturday by Joey Pascarella, 19, of Vacaville, Calif. The finish was one of the tightest on record, with the subsequent three riders finishing within 0.112 second of Pascarella. According to CycleNews.com, Pascarella was the youngest winner of the Daytona 200 since the race switched from the original beach course to the speedway.
