The very first MotoGP of 2015, at the Losail International Circuit of Qatar, started in a manner nobody had anticipated - with Ducati rider Andrea Dovizioso on pole position. Among the usual pole position suspects, Honda riders Dani Pedrosa and Marc Marquez were right up there on the first row, alongside Dovizioso, Yamaha man Jorge Lorenzo started from the 2nd row, while Valentino Rossi was down in the third row of the grid.Given Marc Marquez's dominating performance in 2014 fans expected to see the 22-year-old Spaniard win again at the 2015 season-opener in Qatar. However, someone forgot to tell the Italian from Tavullia, who had different plans. After 20 years in top-level Grand Prix racing, 109 race wins (including yesterday's race at Qatar) and nine World Championships, when most other GP riders would be ready to either retire or move to the relatively softer, gentler world of World Superbikes, Valentino Rossi is still hungry, still has the bulldog-like spirit to fight, which is keeping him at the front of the current MotoGP bunch alongside his much younger rivals.There was some drama on the opening lap of the Qatar GP, as reigning World Champ Marc Marquez ran off the track in the first corner and was only able to re-join the race in last place. Of course, the Spanish rider did fight back and worked his way through the field over the course of the 22-lap race. Ultimately, however, he could not get past the leading quartet of Rossi, Dovizioso, Andrea Iannone and Jorge Lorenzo and finished the race in 5th place.At the front, Rossi, Dovizioso, Iannone and Lorenzo were more or less evenly matched, even though Dovizioso's and Iannone's Ducati GP15 racebikes did seem to have a slight power and top speed advantage over Rossi's and Lorenzo's Yamaha YZR-M1 machines. Dani Pedrosa, also a top contender in the last few seasons, wasn't really in the fray for a podium position at Qatar. Still, despite the problems Pedrosa had with his arm (for which he is now seeking medical care) he put in a brave performance and finished in sixth place.There was a spectacular dog fight between Rossi and Dovizioso in the last few laps of the race, which saw The Doctor using his canny racecraft, and his two decades of experience with close racing, to come out on top. The last three laps of the race saw the Rossi of old, now back in top form, showing Dovizioso a thing or two about how it's done. Rossi, who started the race from 8th position on the grid, ultimately prevailed and came out on top. 'In the last three seasons, I always rode solid races and arrived on the podium, but to come back with a victory is another thing. It was definitely one of the best races of my career,' said Rossi.Dovizioso, who took second place, just 0.174 seconds behind Rossi, made it clear that we can expect more such performances from him and the Ducati team this year. 'After everything we have been through in the last few years, it rewards the work that we have done together to arrive at this point. I never expected to be so competitive in the first race, and it really is an extraordinary result. Iannone and I managed to get two podiums for Ducati and I believe this is only a starting point for the future,' said Dovi. Indeed, this could be Ducati's best year after the 2007 MotoGP season, when the now-retired Australian rider Casey Stoner won the World Championship aboard his 800cc Ducati Desmosedici GP7, with 10 race wins during the year.If the first race of the season is any indication of the 2015 MotoGP season is going to play out, it seems we're in for one hell of a ride. There a young bunch of hungry, aggressive riders at Honda, Yamaha and Ducati, who're not going to back off one inch. And there is, in Rossi, the old guard who's not ready to fade away without putting up a fight. And to make things even more interesting, there are two new manufacturers who've entered the fray with high hopes. There's Suzuki, who had left MotoGP at end of the 2011 season, and there's Aprilia, who last raced in MotoGP back in 2004. With these two manufacturers joining Honda, Yamaha and Ducati, the MotoGP season this year should be more interesting than ever before.
