PGA Tour – The Honda Classic

The 43-year-old Irishman beat American rookie Daniel Berger, 21, in a play-off to win the rain-delayed Honda Classic.

Harrington sealed victory on the second extra hole and qualifies for the Masters after missing out in 2014.

"Hopefully this isn't an isolated win," said the Dubliner.

"I really do believe in myself. I think I've found that mental edge that I've been lacking the last number of years."

Berger posted a six-under 64 to tie with Harrington, who won the US PGA in 2008 and the Open in 2007 and 2008, on six under after a major thunderstorm on Saturday pushed the finish back to Monday morning.

Overnight leaders Ian Poulter and Paul Casey finished joint third on five under, alongside Scotsman Russell Knox. Poulter found the water five times as he shot a four-over 74.

The win lifts Harrington back up to 82nd in the world rankings after beginning the tournament 297th.

The former world number two trailed by four shots going into Monday but surged into contention with four consecutive birdies at 11, 12, 13 and 14.

He double bogeyed the 17th but sank a 15-foot birdie putt on 18 for a 70.

Sunshine / European Tour – Joburg Open

Andy Sullivan produced a brilliant closing 66 to win the Joburg Open and claim a second European Tour title on South African soil in as many months.

Sullivan claimed his maiden title at the South African Open Championship at Glendower in January, just a few miles down the road from Royal Johannesburg & Kensington Golf Club where a 17 under par total saw Sullivan finish two shots clear of compatriots David Howell and Anthony Wall, Ireland’s Kevin Phelan and South Africans Wallie Coetsee and Jaco Van Zyl.

There were also three places in the field at St Andrews available via The Open Qualifying Series, and it was a clean sweep of English players who took them with Sullivan joined by Howell and Wall in the year’s third Major by virtue of their higher position in the Official World Golf Ranking.

The 28 year old Sullivan, the highest ranked player in the field this week, began the final round three shots behind overnight leader Coetsee, but moved to the top of a crowded leaderboard with five birdies in a flawless front nine of 32.

A bogey on the 11th dropped the former Walker Cup player a shot behind Howell, who had gone to the turn in 33, only for Howell to hook his tee shot into the water on the 14th.

Wall's challenge also faltered when he found water on the 15th and it was Sullivan who held his nerve down the closing stretch with birdies on the 15th and 18th to seal victory.

"It's unbelievable," Sullivan said at the presentation ceremony. "I never imagined it would happen again so quickly. Coming down the stretch me and my caddie were loving life again and enjoying it. It seems to be a theme, enjoying my golf and getting the right results at the moment."

Sullivan won a trip into space for a hole-in-one during last year's KLM Open and added: "I think I am already there to be honest with you. I am on the crest of a wave at the moment and I don't want it to end. I just want it to keep going.
