Indian golfer Anirban Lahiri carded a third straight 70 in a roller-coaster performance to lie tied-38th at the Puerto Rico Open here.
Playing once again in windy conditions, Lahiri shot seven birdies, six pars and five bogeys and he is now six-under 210.
Compatriot Arjun Atwal (72) was tied-54 and Daniel Chopra (73) was T-64.
PGA TOUR rookie Viktor Hovland shot 8-under 64 to take a one-stroke lead into the final round. Hovland is looking for his maiden win on the PGA Tour.
Lahiri, starting the day at four-under, opened with a bogey but got back the shot on second. A birdie on fifth was followed by back-to-back bogeys on sixth and seventh and birdies on eighth and ninth. That meant only two pars on the front nine.
On the back nine, he birdied 10th and 12th to get to three-under, only to give away a shot on 13th. He made up with a birdie on 14th and then had three more pars -- the longest stretch of pars for him during the day -- but bogeyed the 18th, where he had a long birdie on first day.
