After another early morning frost delay, play got underway in the second round of the Northwestern Mutual World Challenge, where the tournament host very quickly asserted his presence. Here's how things look after 36 holes at Sherwood Country Club, where Tiger Woods now holds a two-shot lead:
What it means: After failing to capitalize on several opportunities in the opening round, Woods left few if any on the table Friday en route to a 10-under 62, which tied his own course record at Sherwood from 2007. A winner of this event five times over, the world No. 1 now appears poised to add a sixth trophy to his shelf - and win his sixth tournament of 2013.
Round of the day: Woods started with a tap-in birdie on the first hole and barely looked back. In total, he notched 10 birdies in his round - five on each side - and failed to drop a single shot. In the process, he not only surged to the top of the overall leaderboard, but he also bettered the next-best score on the day by five shots.
Best of the rest: Playing Friday alongside Woods, McDowell was unable to keep pace but still netted a 5-under 67 to remain somewhat in contention. Like Woods, the Ulsterman made it around Sherwood without dropping a shot, adding back-to-back birdies at both Nos. 5-6 and Nos. 10-11. He'll begin the third round alone in fourth place among the 18-man field, though that still puts him six shots off the pace set by Woods.
Biggest disappointment: With a world-class field teeing it up Friday, Hunter Mahan was the only player unable to break 80 in the second round. Mahan got off to a solid start Thursday with an opening 69 but ballooned to an 8-over 80 in the second round, failing to record a single birdie while dropping into a tie for 16th place. Mahan's round was derailed early with a bogey/double-bogey start, then the former WGC champion struggled through a five-hole stretch that included four bogeys from Nos. 6-10.
Main storyline heading into Saturday: All eyes will be on Woods, who now appears in position to turn Sunday's final round into more of a coronation. Johnson remains within striking distance though, just three shots back, and the the two have somethingt of a history here, having dueled down the stretch in 2011. Still, after a record-tying performance in the second round that essentially lapped the field, this appears to be Woods' tournament to lose.
