A poor back nine saw Bubba Watson caught by Graham DeLaet and Charley Hoffman as the pair entered the final day of the Travelers Championship in a three-way tie for the lead in Connecticut.

Watson had been three shots clear at the top of the leaderboard at the TPC River Highlands but a round of 70, allied with a 65 by DeLaet and Hoffman's 66, saw him reeled in.

The 34-year-old, who claimed his first tour win at this event in 2010 before being runner-up last year, had started the day in the lead after yesterday's 67.

He returned today and made a fine start, firing birdies on the second, third and sixth holes.

However, the American endured a poor back nine with bogeys on the 13th, 15th and 17th to finish with an even-par 70.

DeLaet, who had dropped off the pace following his 70 yesterday, rediscovered his first-day form to birdie the second and then fire four back-to-back birdies on the back nine, with a 16th hole bogey cancelled out when he picked up a stroke on the 18th.

Ireland's Padraig Harrington lost ground on the leaders after a disappointing round of 72 that involved five bogeys. Harrington is still only four shots behind the leaders but has is it all to do on Sunday.

Hoffman went round in 66 today, with one bogey on the 12th the only blot on his card, as he produced a four-under-par round.

One shot back were Chris Stroud and Nick O'Hern, the former hitting five birdies and just one bogey for a 66 while the Australian continued his consistent tournament with a 68 including three birdies and one bogey.

Ken Duke moved up to sixth with a flawless round of 65 which included five birdies while Justin Rose, who won his first major at the US Open last weekend, was in a seven-way tie for seventh after a 68.
