Rory McIlroy’s road to the Masters hit a speed bump Friday at the Honda Classic. McIlroy made only one birdie in the rain at PGA National at Palm Beach Gardens, Fla., and three bogeys on his last four holes led to a 4-over-par 74. The Honda Classic is considered the start of the buildup to the Masters, and McIlroy is getting more attention than anyone over the last two decades except for Tiger Woods. He already has won this year. [...] a green jacket is all that’s missing for him to become the sixth player with the career Grand Slam. Wallie Coetsee holds a one-shot lead at the Joburg Open in Johannesburg after a 6-under 65 put him 12 under par and at the front of a group of South Africans.
