World number one Rory McIlroy fired his second consecutive four-under 67 on Monday to capture the PGA Tour\'s Deutsche Bank Championship by one shot over South Africa\'s Louis Oosthuizen. McIlroy, of Northern Ireland, finished at 20-under-par 264 for his third victory of the season. He now has five career PGA Tour wins. Oosthuizen closed with an even-par 71 on the TPC Boston to finish solo in second at 19-under. The 2010 British Open champion lost earlier this year to Bubba Watson in a playoff at the Masters. Tiger Woods parred eight consecutive holes beginning at the 10th and then made birdie on 18 for a fourth round five-under 66. Woods finished third at 18-under-par 266. Woods also surpassed the $100 million mark in PGA Tour earnings with his third-place finish. Dustin Johnson (70) and Phil Mickelson (66) tied for fourth at minus-14. It marked Mickelson\'s best finish since the Masters, where he finished in a tie for third. McIlroy, who won the PGA Championship last month, vaults into the top spot in the FedEx Cup standings.
