Roger Penske has apparently found his new team leader. With the future of longtime Team Penske star Helio Castroneves in doubt as he stands trial on federal tax evasion charges, and replacement Will Power new to the team, Penske has placed some added responsibility on the slim shoulders of 27-year-old Ryan Briscoe. Briscoe, starting his second year with Penske, responded Sunday with a victory in the season-opening Honda Grand Prix, outdueling Ryan Hunter-Reay and Justin Wilson for his third career IndyCar Series victory.
