Defending champion Fredrik Jacobson of Sweden maintained his one-stroke lead after Saturday’s completion of the storm-halted second round of the US PGA Travelers Championship.

Jacobson finished with a four-under-par 66 in the second round on Friday at the $US6 million event to be top of the leaderboard on nine-under 131 after 36 holes before storms halted play with 77 golfers on the course at TPC River Highlands.

Play ended just after noon (local time) with Colombia’s Camilo Villegas and Americans JB Holmes and Will Claxton sharing second on 132 with Australian Stuart Appleby and Americans Blake Adams and Roland Thatcher another stroke adrift.

Each man in the trio on 132 was forced to finish on Saturday while the group on 133 all made it into the clubhouse on Friday before play was stopped.

Holmes completed an eight-under 62 on Saturday. He fired five birdies on the front nine and answered his lone bogey, at the par-three 11th, with back-to-back birdies on the next two holes and two more at the 15th and 17th.

Villegas completed a bogey-free 64 that included a run of three birdies in a row starting at the par-five 13th.

Claxton fired a 67 that included an eagle at the par-four 15th.

Jacobson could match Phil Mickelson from 2001 and 2002 as the only players to defend a title in the event’s 60-year history.
