Castroneves has won four pole positions for the Indy 500, including back-to-back poles in 2009 and 2010, the first driver to do so since Scott Brayton in 1996. He is also one of only five drivers – along with Wilbur Shaw, Mauri Rose, Bill Vukovich, and Al Unser being the other four – and the only active driver to win the Indy 500 in back-to-back races.
