( CNN ) -- Ferrari driver Fernando Alonso set the pace during practice for Sunday 's Belgian Grand Prix . The Spaniard was quickest in both the morning and afternoon sessions as his rivals for the drivers ' championship lagged behind . Alonso posted a lap of two minutes , 0.797 seconds in a rain-hit morning session but improved to record a second lap of one minute , 49.032 seconds in the more favorable afternoon conditions . Force India 's Adrian Sutil was 0.125 seconds behind Alonso , while McLaren 's Lewis Hamilton came third . Drivers ' championship leader Mark Webber was left trailing by a full 2.6 seconds . Webber told Formula One 's official website : `` Today was a bit of a messy day with the changing conditions , but it was actually pretty good for us . We got some good information to go through and I 'm looking forward to tomorrow . `` There are a few quick guys out there , but we 're not slow either . It 's hard to get a feel for what everyone 's doing with the changing weather . It 's a beautiful track here , it 's special - today we got to sample it in all conditions . '' After the morning session was dominated by rain , the afternoon stint was delayed by a red flag , then concerns for the crowd after spectators appeared to climb onto fences for a better view of the track . It led to a chaotic end to the final session , but Alonso managed to complete his quickest lap of the day shortly before time ran out . Alonso told the Formula One website : `` The impression one gets on Friday does not always get confirmed on Saturday and Sunday , therefore we have to evaluate today 's results with a lot of care . `` Having said that , it has definitely been a positive day , because the car seems to respond well in all track conditions that we encountered today . '' Renault 's Robert Kubica came fourth , Alonso 's teammate Felipe Massa was fifth , Sebastian Vettel came sixth in the Red Bull , while Jenson Button was seventh overall -- four places behind McLaren teammate Hamilton . `` The weather made it a bit of an up-and-down day , '' Hamilton said . `` It started off very wet , so we did n't do too much running in the morning . But we got a few more laps this afternoon on the intermediates and then the option tire . `` Because the rules do n't allow us to use too many wet-weather tires - we only have three extremes and four intermediates - we really need to look after them , so we were very cautious , just in case we need to use them later on in the weekend . `` We 're definitely making small steps forward . This track does seem to suit our car better [ than in Hungary ] , but let 's not get ahead of ourselves . `` If it rains , then we seem to be competitive , but we have realistic expectations for this weekend - I did n't score in the last race , so it 's important that we get more points on the board on Sunday .
