"I mean, we all played it differently and managed to find ourselves in the same position".
Grillo made back to back double bogeys at the 13th and 14th holes, both after finding the fairway from the tee, but his 6-over day still sees him just two shots off the pace and sharing fourth. "I played great", Wallace said. The man known by many as "Beef" finished his week with a flawless 66 that contained six birdies and no bogeys to get to the same score as Wallace.
Sharma who had started the day at the number one spot failed to take the advantage of his lead and faltered again in the final round as he repeated his final round slip up from the last week's Mexico World Golf Championship.
Johnston shot a final-round 66, Wallace a 68.
During the play-off, Wallace attacked the pin as his second shot sailed over the water hazard and landed on the greens.
Wallace, who won the Portugal Open previous year in only his fourth European Tour event, had built a two-shot advantage after collecting five birdies in his opening 10 holes, including a chip-in at the 10th.More news: President Trump to meet with aluminum, steel execs

It was a birdie after a chip in from the fringes at the last hole which earned him a place at the top after he held the lead briefly on his back nine as fortunes fluctuated too frequently on the third day.
Overnight leader Emiliano Grillo had started Saturday four shots ahead but he ended it two behind after carding 78 that was indicative of the scoring on a day when just nine players fired under par rounds.
He ended up with a bogey in the former before producing a fighting par in the latter.
He closed with a 62 last month to win the Malaysian Open, making him the only two-time victor on the European Tour this season.
"It was a disappointing day for me", he said later. I made a bad swing on the fifth hole, which put me out of contention. "Thereafter, it was all about trying to catch up with the lead". But these things happen. They finished with 11-under totals of 277.
Talking about his future tournaments, the Chandigarh golfer said: "I'm looking forward to a good week of rest next week at home in Panchkula". I'm excited about playing the match-play format after a long time at the WGC Match Play later this month. "I'll have to sit down with my coach Jesse Grewal and prepare my game-plan for the year's first Major which I have watched numerous times on television".
