British raider Justin Rose remains in contention at the Chrysler Championship after a second-round level-par 71 in Florida.
Rose failed to repeat the heroics of his opening-day 65 but is still just four shots adrift of joint-leaders Jonathan Byrd and Jeff Sluman.
Byrd carded a five-under-par 66 to move up to 10 under alongside Sluman, who followed up his course record 62 on day one with a 70.
After firing a bogey-free round with nine birdies on Thursday, Sluman found the going much tougher in the second round, sinking two birdies and a bogey.
“I guess what I said yesterday kind of came true today about some days it’s easy and some days it’s a little more difficult,” Sluman said.
“I had numerous opportunities to make at least half-a-dozen birdies and I just didn’t make them.”
Byrd finally got going after an even-par front nine, the 26-year-old – a two-time winner on the Tour – climbed the leaderboard with five birdies on the back side.
“I obviously played the back nine really well, shooting 31 yesterday and 30 today, so I played some outstanding golf the last two days,” said Byrd, who won the BC Open earlier this year.
Byrd and Sluman have a two-shot lead over world number one Vijay Singh, Tommy Armour III and Rod Pampling.
Armour put together the best round of the day with a bogey-free 64 including seven birdies.
Pampling carded a 65 and Singh, who will become the first player to top the $10m (€7.8m) mark in a season with a solo sixth-place finish or better, followed up an opening-round 65 with a 69.
“I’m in good position and looking forward to playing well in the weekend if I can,” Singh said. “But it’s going to be tough.
“The golf course is not getting any easier and the rough is growing as well, so you’ve got to keep your head and hit it straight.”
The top 125 players on the money list maintain fully exempt status on Tour for the following season.
And, as the season winds down, the players ranked 121-126 were all entered in the field this week.
But it appears the pressure got to some as Billy Andrade (121), Paul Azinger (123), Olin Browne (125) and Craig Barlow (126) all failed to make the cut which was at level-par.
Kent Jones, who entered the tournament in 124th place on the money list, shot second-round 71 to end the day tied for sixth at seven-under.
Aaron Baddeley (122) is on two-under and tied for 35th place.
