IZOD IndyCar Series championship leader Will Power topped yet another session as he led the way in opening practice in Long Beach this morning.

The Australian has a fine record at the track, having won the Champ Car finale there in 2008 and started from pole last year. As the session settled following some frenetic late place-swapping that saw a Ganassi 1-2 swiftly become a Penske 1-2-3, Power emerged on top by 0.1005sec over his Penske teammate Helio Castroneves, another former Long Beach winner.

Target Chip Ganassi Racing's Scott Dixon denied Penske a top-three sweep by pushing Ryan Briscoe back to fourth late on, with Dario Franchitti fifth in the second Ganassi car. Tony Kanaan was Andretti Autosport's top runner in sixth, as his team-mate Ryan Hunter-Reay fell to eighth in the end after a long spell in second. They were split by FAZZT's Alex Tagliani.

Justin Wilson (Dreyer & Reinbold) and EJ Viso (KV) completed the top 10.
