After some highs and lows in the 2010 World Superbike season so far, the Ducati Xerox squad had something of a difficult weekend in England, despite Michel Fabrizio riding hard and well to take fourth in race one.Fabrizio slipped from eighth to ninth overall after Silverstone, Round 10 of the 2010 World SBK Championship, but is still very much in the contest for a top five finish, as he is only 28 points behind new fifth place man, Cal Crutchlow.Fabrizio was resigned to the fact that home advantage played its part in Sunday’s results, and was satisfied that fourth was the best he could do on his Ducati 1098 in race one.Michel Fabrizio says: “Well as we expected, the British riders really had the bit between their teeth today and it was all I could so to stick with them.”“I didn’t expect Haslam to get past when he did but once he did, there wasn’t much I could do about it, but nevertheless I’m pretty satisfied with fourth to tell the truth. In race two my rear tire was moving around a lot and having lost a lot of ground I came in to try to change it but once I went back on track I realized that nothing had changed and, out of the points zone, I retired from the race.”FIM World Superbike Championship Standings (after 10 rounds of 13): 1.
