Monday Motorsports: At IndyCar Opener, Castroneves Rediscovers His Line of Attack With his 2007 victory on "Dancing With the Stars" looking increasingly like a career highlight, Helio Castroneves was overdue for some on-track success. The Team Penske driver picked an auspicious occasion to record his first IndyCar win since 2010, beating a competitive field in St. Petersburg in the first race of the open-wheel series's 2012 season. It was Castroneves's third victory on the street course. It was also the first race since the death of two-time Indianapolis 500 winner Dan Wheldon, and IndyCar was treated to a virtually incident-free return, with just two caution flags flown after Castroneves made contact with Ed Carpenter, and James Jakes drifted lightly into the tire barrier. Castroneves passed Scott Dixon with 27 laps remaining in the 100-lap contest and was not closely challenged for the remainder of the race. Will Power, the pole sitter entering Sunday, lost ground early when a pit stop caused him to drop back in the field. The 2011 runner-up struggled to make up ground, but fought through traffic to finish in seventh place. Dario Franchitti, the four-time IndyCar champion, ran out of fuel in the waning laps, as did Rubens Barrichello, the longtime Formula One driver who made his IndyCar debut at St. Petersburg. Joining Castroneves on the podium were Dixon, who finished second, and Ryan Hunter-Reay. The drivers reconvene on Sunday at Barber Motorsports Park in Alabama. Fernando Alonso surprised critics by putting Ferrari atop the podium on Sunday, winning a rain-plagued Malaysian Grand Prix ahead of the Sauber driver Sergio Peres, who delivered the best-ever race result for the team as a nonmanufacturer entry in Formula One. Lewis Hamilton, the race's pole sitter, rounded out the top three for McLaren. It was Alonso's first victory since the British Grand Prix at Silverstone last July, and a surprising result, given Alonso's public skepticism about the engineering of the team's 2012 racecars. Tony Stewart, the 2011 Nascar Sprint Cup champion, won a rain-shortened race at Auto Club Speedway in Fontana, Calif., his second victory in the first five races of the 2012 season. Stewart passed Kyle Busch with 44 laps remaining before the race was called for heavy rain. Ultimately, he was pronounced the winner of the race, which was abbreviated by 71 laps. Dating back to last year's postseason chase, Stewart has won seven of the last 15 Sprint Cup races. The Williams Formula One team announced Monday that its director, Adam Parr, would resign from the program, effective Friday. Mr. Parr joined Williams in 2006 and was appointed its chairman by Frank Williams, the team's founder, in 2010. His replacement, Nick Rose, is a former executive for Diageo, the wine and spirits conglomerate.
