American Stewart Cink held on to his lead at the Travelers Championship at the TPC River Highlands in Cromwell, Connecticut, after a third-round 65 put him two clear of compatriot Heath Slocum.

Cink extended his advantage by one in moving to 15 under with a day to go, although Vijay Singh is just three behind after a six-under-par 64.

Kevin Streelman, DJ Trahan and Chad Campbell all had best-of-the-day rounds of 62 to remain in touch but England's two representatives are well off the pace.

Justin Rose bounced back from Friday's two-over 72 to shoot 66 and move up to seven under while Londoner Brian Davis could manage only a 69 to join his fellow countryman in a share of 31st.
