Graeme McDowell and Luke Donald both have a chance to win golf's richest event this weekend after solid second-round efforts at the Players Championship at Sawgrass.
The Ryder Cup team-mates are both on eight under par and joint third, just two behind American David Toms at the halfway point in the £5.8million tournament.
Donald needs to win to overtake both Lee Westwood and Martin Kaymer and become world number one but the World Match Play champion has yet to drop a stroke and, after birdies at the 16th and 17th, parred the last for a superb 67. McDowell signed for a 69.
Donald said: "It's very satisfying not have any bogeys so far. I played better today, the 14th was the only hole I struggled on.
"There was a lot of grind yesterday and today was more a cruise-control day.
"Hopefully I'm stepping up and getting better. I obviously gained a lot of confidence from my win and I feel good about my game.
"My short game's been good for a couple of years, but now I'm starting to hit more fairways, more greens and give myself more opportunities."
Former US PGA champion Toms became the man to catch when he followed up his first-day 66 with a 68 to stand 10 under.
He was one in front of first day pacesetter Nick Watney, who added a 71, and two ahead of not only McDowell and Donald, but also Steve Stricker and last week's winner Lucas Glover.
Londoner Brian Davis would have been on the same mark had he not double-bogeyed the fourth - he hit his approach into the water on what was his 13th hole - but he came back with two birdies for another 69.
