further places to Rosberg and Kovalainen as a result of the incident. Räikkönen would latterly be investigated after the race for both of his first lap incidents. At the end of the first lap, Sutil came into the pits from 19th place with water pressure problems. The problem was terminal and he became the first retirement of the afternoon. Alonso started to pull away from the field, setting his fastest lap of the race (1:23.529) on lap four. Positions remained static until the start of lap five. Hamilton pressured Webber in turn one, and with the aid of the KERS button, overtook the Australian before turn two. Once clear of Webber, Hamilton started to cut into the gap that Alonso had built up at the front. Alonso's Renault was suffering from graining on its rear tyres (when the tyres shed little bits of rubber before sticking to the tread of the tyre, effectively separating the tyre from the track surface very slightly), and also a fuel pump problem, which forced him to change to a different fuel setting on the car. Alonso pitted on lap twelve, and was stationary for 6.4 seconds. However, he was released with his front right wheel incorrectly attached, causing the wheel-mounted brake duct or "spinner" to rotate while the wheel was turning. The duct then fell off and disintegrated at turn four, as Alonso continued to go round the circuit. The wheel then parted from the car at turn nine, and Alonso drove the car back to the pits on three wheels. The missing wheel was replaced, enabling him to continue in the race, but he returned to the pits on the following lap, as the earlier fuel pump problem proved terminal. With Hamilton extending his lead to almost six seconds—including his fastest lap of 1:22.479 on lap sixteen—Räikkönen and Webber both pitted on lap nineteen. Räikkönen was at a standstill for 8.3 seconds, while a slight problem with the fuel rig cost Webber valuable seconds. He was eventually released just as the Ferrari was trundling down the pit lane. The two cars just avoided a collision, which almost caused the Red Bull to career into a number of the Williams mechanics, who were standing in the pit lane at the time. Hamilton pitted the following lap, but was slightly delayed by Rosberg's Williams, which had entered the pit lane as Hamilton was about to
