Jeev defeated Francesco Molinari in a dramatic play-off to claim his fourth European Tour title at the Aberdeen Asset Management Scottish Open.
Jeev, who finished 17 under for the tournament following a sublime final day five under 67, won with a 15-foot birdie putt at the first play-off hole, played at the 18th.
It is his first victory on the European Tour since he triumphed at the Austria Golf Open in June 2008 and replaces the Nordea Masters, where he was seventh, as his best result of the season. He also took the last qualifying place for the Open at Royal Lytham and St Annes next week.
The win marked a fine return to the winner’s circle for the Indian, who has battled injuries in recent times.
Jeev remained calm at the prospect of a play-off, despite having to wait for more than an hour in the players’ lounge following his round.
"I was just enjoying a cup of tea and some chocolate cake and watching it on television, and suddenly got excited," he said.
"I think God has been kind, and I think the field came back and I put myself in a to go in for a play-off - I'm very fortunate.
"I would like to thank a lot of people who have been by my side the last three, four years that have been a struggle for me with the injuries: my family, my friend who coaches me, Janet, who was on my bag, my sponsors who stood by me like Callaway, UPS, Societe Generale, golf in DUBAi.
"All of these guys have been great and supported me through a tough time and I want to thank them all for this.
"It has been really tough - frustrating more than anything else. You feel like your game is coming back and another injury creeps up, but I just stuck myself in there and said that you need to work on the physical side, and I worked hard on that.
"Everything has paid off, and I just want to think about the good things and not what's past and I want to look towards the future now."
