when Sébastien Buemi crashed. He was on course to finish fifth with Button behind, which would have been enough for Brawn GP to clinch the Constructors' Championship, but a safety car period in the closing stages of the race for Jaime Alguersuari's crash meant that Nico Rosberg and Heidfeld were able to stay out ahead and save fuel, dropping Barrichello to seventh. With Button finishing eighth, Barrichello closed the points deficit to fourteen and putting Brawn almost out of reach for the Constructors' title. In Brazil, Barrichello claimed pole in a rain-soaked, qualifying session with title rivals Button and Vettel down the order in 14th and 16th, respectively. A puncture cost Barrichello a chance of taking the title to the final race, as he failed to secure enough of an advantage over Button to do so. Button finished fifth to become champion. In Abu Dhabi he qualified and finished 4th. With Vettel winning the race, he secured second in the standings, with Barrichello finishing third in the championship with 77 points. Williams (2010–2011) In 2010, Barrichello was offered a contract by McLaren. He did not accept because he had already signed a contract with Williams, and did not want to renege on his pledge to that team. The McLaren seat was ultimately filled by Barrichello's 2009 teammate Jenson Button. On 2 November 2009, Williams confirmed Barrichello and Nico Hülkenberg as their official race drivers for the season. This meant that Barrichello would be in Formula One for at least another season, and would go on to become the first driver in Formula One history to compete in over 300 Grands Prix. In pre-season testing, Barrichello finished at the top of the timesheets once, because of rain. In some sessions, he was outpaced by his rookie teammate Hülkenberg. Williams was the second team in terms of kilometres covered and showed some reliability, but were off pace from front-runners Red Bull, Ferrari, and McLaren. At the first race of the season in Bahrain, Barrichello qualified eleventh on the grid, and finished tenth in the race. In Australia, he went on to finish eighth, moving him to within two points of Senna's mark. He stalled on the grid in Malaysia due to an overheating clutch, but recovered to twelfth place at the finish. In China, he finished twelfth again. In Spain he benefited from Lewis Hamilton's late crash to score two points, finishing
