Lorenzo Zanetti continued his recent good form in the fifth round World Supersport race at Donington Park in the UK, following up his podium at Monza two weeks ago with a spirited ride to fourth place.While Zanetti continues to impress in his debut World Supersport season, todays race was won by series leader and local rider, Sam Lowes, who extended his lead at the top of the championship table. Zanetti moved up to fourth, leapfrogging his Pata Honda team-mate Michael van der Mark, who endured a difficult Donington weekend.After breaking his foot at Monza, van der Mark has been rehabilitating with Superbike colleague Leon Haslam but a technical problem in qualifying restricted the 20-year-old Dutch rider to 20th place on the grid.Van der Mark got a good start and had climbed seven places before crashing unhurt at Doningtons Melbourne Hairpin, remounting to claim 20th place after 22 hard laps of the 4.023km circuit.Lorenzo Zanetti4thFourth position was not so bad today and it was good to continue the recent improvement and the points were good for the championship. I spent more than half the race in third position so I thought the podium was possible but Rolfo arrived with an incredible rhythm. I tried to fight him but I lost the rear a few times and lost a lot of time. On the first two or three laps I lost some time trying to pass Marino and when I passed him, Kenan [Sofuoglu] had two or three seconds on me. We have continued to make progress here and it is important to continue this in Portimao.Michael van der Mark20thIt was a little bit frustrating today because I made up seven positions and got up to 13th place and I was trying to catch the group in front because it was quite a big group. I closed the gap a little bit but braked a little bit too hard and lost the front at the hairpin. Its a shame because we had some problems all weekend and we wanted to get some points. I hope in Portimao we can have a better weekend than this.Pieter Breddelstechnical co-ordinatorUnfortunately, Michael had to come from a long way back but made up some places at the start. In trying to close the gap more to the front he had a little front-end crash. He wasnt able to get into the points, which is a shame, so we hope for better luck at the next race. Lorenzo did exactly what we had hoped for which was running for the podium. It wasnt quite possible but fourth place took him past Michael in the championship, so well done to him. He has definitely made a breakthrough with the bike and were looking forward to Portimao with both of the guys.2013 World Supersport championship, round fiveDonington Park, UK4.023kmkm, 22 lapsRace result:1 Sam Lowes (GBR) Yamaha 2 Kenan Sofuoglu (TUR) Kawasaki 3 Roberto Rolfo (ITA) MV Agusta 4 Lorenzo Zanetti (ITA) Pata Honda 5 Luca Scassa (ITA) Kawasaki 6 Jack Kennedy (IRL) Honda 20 Michael van der Mark (NED) Pata HondaChampionship points after five of 14 rounds: 1 Lowes 95, 2 Sofuoglu 65, 3 Foret 61, 4 Zanetti 53, 5 van der Mark 49, 6 Scassa 45.Next round: Autodromo Internacional do Algarve, Portugal7-9 June
