Harrington and Clarke make up the numbers at Innisbrook

Australia's John Senden, 42, ended a seven-year PGA Tour drought in the Valspar Championship. 

Pádraig Harrington will have been encouraged to see John Senden end a seven-year PGA Tour drought in the Valspar Championship at Innisbrook.

The 42-year old Australian made two huge birdies in the Snake Pit on a windy final day, carding a one under 70 on the treacherous Copperhead Course to win by a stroke from Kevin Ka on seven under par.

Just four months older than Harrington, Senden earned a spot in the Masters field next month and while the Dubliner has also endured a long drougt in the US — his last win came in the 2008 US PGA Championship at Oakland Hill nearly six years ago — he still has three more chances to win and avoid missing the trip to Augusta National for the first time since his debut in 2000.

If Harrington is to win at Bay Hill, San Antonio or Houston over the next three weeks, he's going to have to improve on his performance in Tampa, where he had three birdies, four bogeys and a double bogey six in a closing 74 that left him tied for 65th on seven over par.

As Darren Clarke fashioned a final round 72 to take 58th spot on six over, Harrington started and finished his day with birdies but finished 70th for putting and struggled off the tee for much of the week.

As for Senden, he was tied for the lead when he chipped in from 70 feet on the 16th and then birdied the 17th from 20 feet before ably two-putting the 18th from 40 feet for what turned out to be a winning par four.
