Jeev, who had last won a title in 2008, also qualified for the British Open next week at the Royal Lytham and St. Annes.
"He is happy with his win. I had a chat with him and he said he was feeling great as the victory has come after a long gap," Jeev's 82-year-old father Milkha Singh said here today.
The 'Flying Sikh' said he had virtually no hope initially that Jeev would win the Scottish Open.
"I was closely following his game. It was a tense play-off for us and we did not miss a moment. He played well and the win has come at the right time for him as he had been struggling with injury. He made a remarkable comeback," he said.
"Throughout night we did not sleep as we kept getting congratulatory telephone calls from friends and well-wishers in India and abroad," said Milkha.
The legendary athlete said Jeev would be arriving in Delhi next week, where he would be honoured by Delhi Golf Association.
