Cal Crutchlow's hopes of winning his first World Superbike race at Monza were spoiled by kicked up stones that left a hole in his Yamaha's oil cooler.

Crutchlow was destined for the best WSBK weekend of his career as he ran close behind eventual winner Biaggi during the second race, the Briton eager to go better than his fine third place finish in the opening encounter.

However, Crutchlow's weekend would end in the gravel trap on lap 13 when he spun on his own oil, which had begun leaking from a hole caused by stones being kicked up the Aprilia ahead.

A disappointing conclusion to what had been a positive weekend from Crutchlow, the reigning World Supersport Champion was frustrated with his lack of luck, but happy to be back on the podium.

"I felt like I put together a really solid first race, we didn't get the best of starts but made up for it and got stuck in," he said. "All credit to Yamaha, they've done a good job to give James and I a competitive package so it was great for us both to deliver them the podiums here for their home round. It was a strong result and we rode well so I was looking forward to the second race.

"I started really well and didn't take long to get tucked in behind Max, I knew exactly what I was doing and had my strategy sorted to pass him on the last lap. Incredibly some stones flew up off his back wheel, I was so close behind I felt some hit my helmet and unfortunately a big one made a hole in my oil cooler.

"I made it through another lap, but coming into the first chicane it must have reached my back tyre and I went straight down."

Cruelly, despite this being arguably Crutchlow's best race weekend this season, he has actually slipped a position to 11th in the overall standings.
