Rory McIlroy targets top-four BMW Championship finish to maintain FedEx Cup hope

Former world number one Rory McIlroy needs a top-four finish in the BMW Championship to make certain of having a chance of retaining his FedEx Cup title.

McIlroy enters the penultimate play-off event at his lowest world ranking for more than three years, a missed cut in the Dell Technologies Championship seeing him slip from fourth to sixth in the standings behind US PGA champion Justin Thomas and Spain's Jon Rahm.
