Ryan Moore leads the Travelers Championship by a single stroke from Australia's Aaron Baddeley heading into the final round.
American Moore carded a four-under round of 66 - which included an eagle on the par-five sixth hole - at TPC River Highlands to keep both Baddeley and Sergio Garcia at arm's length.
Baddeley mixed six birdies with a bogey to finish five under after the third round, a score Spaniard Garcia matched on Saturday, but he is a further stroke off the lead thanks to his second-round score of 69.
Tied for third place with Garcia are Americans Scott Langley and Michael Putnam, while their countrymen Kevin Streelman and Nick Watney impressed in Connecticut to climb the leaderboard.
Other than a bogey on the third hole, 35-year-old Streelman - with one PGA Tour title to his name - made no further mistakes as he claimed seven birdies for a 64 total leaving him nine under ahead of the final round.
Joining him four shots off the lead was Sacramento's Watney, who hit a flawless front nine in which he recorded three birdies but two bogeys among four further birdies on the back nine pegged him back to a third-round 65.
Sweden's Carl Pettersson improved his score by one shot for the second consecutive day as he posted a total of 66, impressing with three birdies over the last four holes to remain in contention alongside Streelman and Watney.
Winner of the 2009 Masters Angel Cabrera was two shots further back following his third round in which the Argentinian claimed a total of eight birdies, a bogey and a double bogey to card a 65.
Also on seven under were Australia's Marc Leishman, who scored an eagle on the 15th hole, and American pair Hudson Swafford and Tommy Gainey.
Overnight leader Langley suffered a poor start to his round with bogeys on the fourth and fifth before a birdie on the sixth brought him back to one over total of 36 on his front nine.
The Illinois golfer had crept to the top of the leaderboard on Friday to lead by one shot after posting 65.
