“I don't think it's hit me yet,” she said. “I was almost planning where I was going to go for dinner, whether we could get an early flight home, all that kind of stuff.
“But then I got to 10, 11, 12, and I said to myself, ‘you know what, if she's going to win this match, she's going to have to win this match. Let's dig deep. You've come from behind before; you can do anything you set your mind to’.
“I'm really ecstatic with that win because I think I just proved to myself that I can do anything.
“I honestly think I felt less pressure being four-down with five to play than I did being three-down after the first three holes. I was standing on the 4th tee box and I'm like, ‘I don't know what to do, I don't know what just happened’.
“Paula is a great player so it (the final) is going to be a long day but I’m there for it. As long as I keep playing Farah golf, then anything can happen.”
In the other semi-final, Martin Sampedro, who beat her compatriot Paula Francisco in the morning’s quarter-finals and employed her friend as her caddie in the afternoon, enjoyed a 3&2 win over Italy’s Caterina Don.
With a composed, clinical display, the Spaniard’s bunker play, in particular, was exceptional. Two-up early on, a crucial up-and-down from the sand at the 9th preserved that lead while another neatly executed bunker escape on the 10th helped extend it to three. When Martin Sampedro holed an 18-footer for a birdie on the 14th, her fist pump underlined the significance of the moment.
Don, making just a second appearance in a major amateur event this year, showed admirable resistance to battle back and birdied the 15th to keep her gallant bid alive but Martin Sampedro closed out the match on the next hole.
