Fitzpatrick had chances to get into a playoff but missed both an eagle putt on the 17th hole that lipped around the cup and a birdie effort on No. 18. It was Wiesberger's third win of the season after Denmark in May and the Scottish Open — which is also in the Rolex Series — in July. The 34-year-old Austrian also finished in a tie for second in the Irish Open.
"I've played really well in the right events," said Wiesberger, who finished 16 under overall. "Just really excited what's ahead of us in the last few events." Wiesberger has 4,198 points in the Race to Dubai, ahead of Jon Ram (3,898), British Open champion Shane Lowry (3,535) and Fitzpatrick (2,865).
He joins Rahm, Alex Noren, Justin Rose and Danny Willett as multiple winners in the Rolex Series. It was the seventh career win on the European Tour for Wiesberger, who missed the last seven months of last year with a wrist injury.
"I've been really good putting myself in positions and staying there," Wiesberger said after earning a winner's check of $1.1 million. "I just really enjoy my time and being back out there, because I know how tough it was when I had to withdraw from these events last year. It's just really full enjoyment out there when I'm in position."
Wiesberger also moved to a career-high 22nd in the world golf rankings, boosting his chances of making a Ryder Cup debut next year. American Kurt Kitayama finished third, four shots behind Wiesberger and one stroke ahead of Andrew Johnston, Robert MacIntyre and Matthias Schwab.
Francesco Laporta was the top Italian in a tie for seventh while Andrea Pavan tied for 10th on his home course. With a $7 million purse, the Italian Open returned to Rome after 17 years as the local federation attempts to boost interest ahead of the 2022 Ryder Cup at the nearby Marco Simone club .
Total attendance for the four days was 29,000. "This week couldn't have been better in terms of re-embracing Rome and preparing for 2022," said Italian golf federation president Franco Chimenti. "We had four days of perfect sunshine — which is something we're used to in Rome."
Chimenti announced that next year's tournament will also be played at Olgiata, before the tournament moves to Marco Simone in 2021.
