Andrea Dovizioso was thrilled to make up for a missed opportunity earlier in the season by ending a seven-year wait for glory at the Malaysian MotoGP.
The Ducati rider became the ninth different race winner of the 2016 campaign on Sunday, capitalising on an error from Valentino Rossi to triumph at a sodden Sepang International Circuit.
After recording his first win since the 2009 British GP, Dovizioso revealed he had been motivated by a desire to improve on his runner-up finish behind team-mate Andrea Iannone in Austria earlier this year.
"This victory was important for me," said the Italian. "In Austria, I felt that victory was mine, but I made the wrong decision. So to get this result now - this year - is very important.
"A lot of people work hard at home and to win with Ducati is something different."
Dovizioso added: "At the start of the race there was a lot of water and the pace was very fast, but I didn't make a mistake and I'm very happy about that because it allowed me to fight for the win later on.
"When the conditions are like this anything can happen, but I've done a lot of races in these conditions - I didn't think much about the weather because we can't control it."
The final race of the season in Valencia next month will see Jorge Lorenzo bring an end to his lengthy association with Yamaha, which has featured three premier-class world title wins.
Lorenzo, who finished third on Sunday and will join Ducati ahead of the 2017 campaign, said: "Valencia will be an emotional moment because nine years with one team who gave me so much is emotional.
"I'll train and give my best and finish in the best way possible."
