Shane Lowry recovered from a terrible start to his second round at the Honda Classic Open to remain in title contention.
The Open champion shot three bogeys in his first four holes on Friday to drop to three over par, but responded with successive birdies before chipping in from 20 feet for an eagle on his ninth hole.
Lowry hit two birdies and two bogeys on the back nine to card a one-under-par 69 for the second successive day.
England's Luke Donald was one of the big movers on Friday, his round of 66 moving him onto four under par, two shots clear of Lowry.
Leading the tournament at the halfway mark was Brendan Steele. The American followed up a 68 on Thursday with a 67 on day two to take a one-shot lead.
Padraig Harrington missed the cut after a second-round 74 saw him drop to six over par.
