Windemere, FL (SportsNetwork.com) - Playing in the final group Friday, Jordan Spieth leads by two shots and he faces a chip shot on the final hole as second-round play was suspended due to darkness at the Hero World Challenge.

Spieth, the first-round leader who was 5-under on the day, decided to finish up his round on Saturday with his ball just off the front of the green on No. 18. Spieth is currently at 11-under through 35 holes and he leads Henrik Stenson by two shots.

"I think if it were a normal event and we weren't the last group the horn would've been blown probably when we were on 16 green," said Spieth. "It got pretty dark. I don't know if the cameras did it justice. If I did it over again I may have stopped playing on 17 but I thought we may be able to get it in here."

Heavy rain delayed play for about an hour and a half, forcing most of the players in the final few pairings to finish up their second rounds in the dark at Isleworth Golf & Country Club.

Steve Stricker, playing in the penultimate group, was on the 18th green when he decided to call it quits for the day. Spieth and Stricker are the only ones who still need to finish their second rounds. Stricker was even par on the day and is tied for 12th at minus-5.

Stenson started off on fire and held the lead at one point, but he struggled after the weather delay. Stenson carded a 4-under 68 and he is in second place at 9-under 135.

Patrick Reed flirted with a 59 early on in his round, but he slowed down a bit coming down the stretch. Still, Reed followed up his 73 Thursday with a 9- under 63 Friday and he is tied for third with Justin Rose (64) at 8-under 136.

Tournament host Tiger Woods improved on his 77 in the first round with a 2- under 70 Friday, but a tough finish still has him in last place at 3-over 147.

Spieth was rather quiet on the front nine, which allowed Stenson to grab the lead at one point. Following a pair of pars on one and two, Spieth drained his first birdie on the par-5 third. Three holes later, the 21-year-old tripped to a double-bogey on No. 6, putting him at 1-over for the day.

Spieth got one of those shots back with his second gain on the par-5 seventh, getting him back to even par. After closing the front nine with two pars, Spieth caught fire on the back side, making five birdies in a seven-hole stretch from 10.

With the sun having already set, Spieth finished up No. 17 with a par and his second shot on the par-4 18th came up just short of the green. Instead of chipping in pure darkness, Spieth decided to finish up Saturday morning, while playing partner Zach Johnson finished up his round.

"With a tricky lie down there into the grain, it's just a good idea to hit that pitch tomorrow when I can't really even see the flag stick from about 30 feet away," Spieth said. "It's muddy after this rain and it's just a tricky lie. If I were on the green I probably would have putted it. I can probably see well enough to hit a good putt, but setting the wedge down would've been tricky there."

Stenson rode his hot start into the lead as he made four birdies on his first six holes on one, three, four and six. Following four straight pars from seven, Stenson continued to play well with gains on 11 and 13.

After the rain delay, Stenson struggled as he tripped to back-to-back bogeys on 15 and 16. He was able to finish up his round with a pair of pars to remain in second place and two shots back of Spieth at the end of the day.

Reed fired the lowest round of the day and was on fire from the start. The 24- year-old started off with three straight birdies from one and followed up with two pars on four and five. Reed was really on 59 watch after he rolled in a birdie on six, an eagle on the par-5 seventh and two more gains on nine and 10.

At 8-under through 10 and needing to play the final eight holes at minus-5 in order to shoot a 59, Reed slowed down a bit. He bogeyed his first and only hole on 12 when his second shot found the water, but Reed responded with another gain on 13. He finished up his round with four pars and a birdie on 16.

"After I birdied 10 I think it kind of got in my mind," said Reed about the possibility of shooting a 59. "I thought about it for about 11 and 12, and after that I was like you just need to get back and play golf. You need to do what you did on the front nine and that's focus on each shot and try to get the ball in the hole as fast as possible."

Rose also had an incredible day that started off up-and-down. Rose made birdies on one and three, but gave those shots back with a bogey on four and a double-bogey on five.

Then came a huge run for Rose as he finished up the front nine with four straight birdies from six. After a pair of pars, Rose continued his run as he drained five more birdies on the final six holes from 12, making it nine birdies on his final 13 holes following a par at the last.

Woods rebounded well after a rough first day, starting with a birdie at the first. He then coasted through the next six holes with six straight pars before dropping his first shot with a bogey on No. 8.

Making the turn at even par for the day, Woods made his first eagle of 2014 from about five feet on 13, which seemed to spark his game a bit. Woods went on to make birdie on two of the next three holes on 14 and 15, getting him to 1-over for the week.

On the 18th just after the delay, Woods pulled his second shot well left and proceeded to chunk his chip shot. He then chipped on and two-putted for double-bogey, giving a sour ending to Woods' otherwise successful day.

"To be honest with you it really wasn't a whole lot different," Woods said about his round on Friday compared to his first round. "I maybe have hit two less worse shots than I did yesterday, but it really wasn't that much different."
