The start of all three races today have been full of drama. This time into turn 8a on the second lap three bikes just went straight on through the grass. Danny Eslick was involved as was Ben Bostrom and they allowed Josh Hayes on his Monster Energy Graves Yamaha R-1 to walk away from very early on.

Josh Hayes confirmed he will be on the pole position for the Great Clips West Coast Moto Jam pair of SuperBike Races in Sonoma California, with a 1:35.872. AllAboutBikes predicted in yesterday's practice sessions that the top SuperBike racers would see themselves finishing in the 1.35 zone, and that is exactly what Hayes did to clinch the pole position.

With over 800th of a second between them at 1:36.775 Roger Hayden on his National Guard Jordan Suzuki was the closest to the pole sitter.

Jason DiSalvo made the pole again this year at Infineon, on a totally different machine to last year. He swapped his Ducati 848 Team Latus Racing for a Triumph 675R Team Latus Racing machine.

And when asked about the differences between the two machines at this track his response was " The Triumph is so nimble down this back twisty section through 7, 8 and 9 all the way to the chicane. Also it is really balanced, this is probably one of the most creative I have been here at Infineon raceway, with corner entries, backing the thing in, sliding it, I feel like I am riding a dirt bike in my back yard. I feel like I can do anything on this bike."

DiSalvo's pole time was 1:38.159.

James Rispoli is sitting on pole for the AMA Pro Motorcycle Superstore Supersport race at Infineon Raceway CA.

Rispoli made the front row on his Suzuki GSX-R600 Celtic Racing. Oriental Express. Army National Guard motorcycle. James made the pole with a lap time of 1: 41.238 He mentioned in the press conference that he was a "little nervous coming into the session this morning. This is the first time on a real race bike Rispoli said, last year I was riding a stock GSX-R600 with Ant Racing, so the bike change this year really tightens the track."

Josh Hayes stays on the top of practice at Infineon AMA Pro National Guard Superbike.

The wind picked up towards the latter part of the second session of practice 1 of the AMA Pro National Guard Superbike practice.
