Lauren Walsh fell four shots off the pace after a difficult third round at the Tenerife Women's Open.
The Kildare golfer held a two-stroke overnight lead after rounds of 67 and 68 over the opening two days in Spain, briefly holding a four shot advantage at one stage on Friday.
But Walsh endured a tough afternoon on Saturday, beginning with a dropped stroke on the first and then a sequence of bogeys around the turn at 8, 10 and 11.
A double-bogey on the 14th saw her fall to three-under and flirting with the 80 mark before she salvaged something with a birdie on the penultimate hole to clamber back into the top 10.
Walsh will enter the final round four strokes adrift on four-under, with Czech Republic's Sara Kouskova holding a one shot lead on eight-under after a fine round of 69.
She is one clear of a trio of golfers on seven-under, comprised of Spain's Ana Pelaez Trivino, Finland's Noora Komulainen and Singapore's Shannon Tan.
