Stephen Gallacher is hoping to conjure up a text book performance in the Turkish Airlines Open after leafing through the pages of one of golf’s great instruction manuals.

The Bathgate man is one of five Scots competing at the Regnum Carya resort in Antalya in the first event of the European Tour’s three-stop Final Series which is worth a whopping $22.5 million.

Gallacher is in the midst of changing his swing which was enforced due to a hand injury but with the tweaks and tune-ups, the former Ryder Cup player has struggled to find the consistency required to compete the top level.

But a read of Practical Golf, the bible of hints and tips from the celebrated doctor of golf, John Jacobs, has given Gallacher a bit more understanding of what he is trying to do.

He said: “My uncle Bernard sent up John Jacobs' book. The tough thing in this process has been the need to change my grip. I've got to weaken it.

"It feels horrendous but the shots are better and that's what matters. I read the book and I then spoke to my coach about it. He said it was the answer. It comes from me. I've not been as consistent as I want to be and I’ve been missing it left a lot.

"It's not enjoyable when you have a week playing well then a week playing bad. It just wasn't gelling together swing-wise. I was becoming kind of one-dimensional and I can't see the game that way. I need to see it in shapes and weakening my grip is allowing me to do that.”

Gallacher, who is 78th on the Tour’s rankings, is not yet guaranteed a place in next week’s Nedbank Challenge in Sun City and needs to be in the top-60 of the money list to earn a place in the season-ending Tour Championship in Dubai.

With huge amounts of money up for grabs this week, the three-time Euro Tour champ knows one big result can provide a huge spring board.

He added: "It's a case of trying to do as well as I can here to get into Sun City and then try to get into Dubai. It's three massive events that can be game-changing for your goals if you win one of them.

"It's important to be playing in these ones if you want to give the Ryder Cup a try and what a great opportunity to get yourself back into the top 100 or even the top 50 of the world again."
