Lowes got a good start in the 10-lap Superpole sprint race but was forced to do it all again when the race was stopped on the second lap, following a crash at the Corkscrew for Yamaha wildcard rider JD Beach and Honda's Alessandro Delbianco.
Lowes ended he restarted eight-lap sprint race in sixth position, to secure a second row start for Race 2. Another good start in the feature race saw Lowes immediately embroiled in a battle with Tom Sykes and Leon Haslam for fourth place.
The battle continued until just past half race distance when the Pata Yamaha rider made his move to pass Sykes and then pull away from his two pursuers to finish fourth. With 28 points from the three races this weekend, Lowes moved up the championship standings to third place, where he now has a five-point advantage over teammate van der Mark in fourth.
After a crash in qualifying left him 15th on the grid, van der Mark went into the Superpole race determined to finish inside the top nine and secure a starting position on the front three rows of the grid for Race 2. Unfortunately, the Pata Yamaha rider missed out by just one place, finishing the shortened race in tenth position.
A lightning start from the fifth row of the grid saw van der Mark cross the line at the end of the opening lap in tenth place and targeting the group ahead of him battling for fifth. The Pata Yamaha rider's challenge came to a premature end, however, when a technical problem forced his retirement from the race on lap four.
Loris Baz enjoyed a solid weekend in America, with seventh place in today's 25-lap feature race making it three top-ten finishes at Laguna Seca for the Ten Kate Yamaha Supported WorldSBK rider. The Frenchman moves up to 13th place in the championship standings with 76 points, despite having only contested three of the nine rounds this season.
It proved a more difficult weekend for the GRT Yamaha Supported WorldSBK riders, Sandro Cortese and Marco Melandri, but for different reasons. Cortese, making his debut at Laguna Seca this weekend, struggled with the effects of a shoulder injury sustained in his Donington Superpole crash and had to ride through the pain to pick up 2 points in 14th place today.
Melandri fared better, securing his second top ten finish of the weekend in ninth, despite struggling to make up for a starting position on the sixth row of the grid in the early stages of the race. At the halfway point the Italian was matching the lap times of the leading riders, but by that time the gap to the group ahead of him had stretched too far for him to regain contact and he was forced to settle for ninth place at the line.
