Stefani still out in front
PGA Tour rookie Shawn Stefani maintained his place at the head of the leaderboard midway though the second day of the Tampa Bay Championship.
Stefani failed to scale the heights of his opening-round 65, settling for a more modest one-under 70 as he held on to the clubhouse lead at seven under.
The American led by one stroke from Australia's Adam Scott, who followed up an opening 70 with a much-improved 66.
Scott sat one stroke clear of a trio of Americans tied for third place in the clubhouse, Jason Dufner's 66 moving him into contention alongside Harris English (69) and Brian Harman (70).
Australia's Greg Chalmers was posing the biggest threat to those in the clubhouse, hitting five birdies through 11 holes as he moved on to five under overall after opening with a par 71 yesterday.
Tag Ridings and Peter Tomasulo were also on five under through 10 and three holes respectively.
England's Brian Davis was in a tie for 15th on two under after 10 holes of his second round, while compatriot Luke Donald's struggles continued as he hit two bogeys in his first seven holes today to drop to one over par for the tournament, just a stroke clear of the projected cut.
