The 46-year-old carded a one-under final round of 71 to finish level par for the tournament, placing her 29th overall.
South Korea’s Inbee Park, pictured, claimed the gold with a closing 66 at Reserva de Marapendi to finish 16-under, five shots clear of world No.1 Lydia Ko, who birdied the last to claim silver ahead of China’s Shanshan Feng.
For Matthew, a triple bogey at the 12th hole in her third round on Friday put an end to her medal charge – she had been tied for 13th at the halfway stage.
Yesterday’s final round was a chance for the 2009 Women’s British Open champion to test out a few things to help improve her game, putting being the major focus. And after walking off the 18th green with a smile on her face, Matthew admitted she is optimistic something may click before the end of the season.
“I played pretty well, I hit 16 greens and holed the odd putt, I probably should have holed a few more but it was a decent round to finish,” she said.
Park took a two-shot lead into the final round and was six clear after a hat-trick of birdies from the third and another on the eighth, before Feng closed the gap with a birdie on the 10th.
And when Park bogeyed the 10th after pulling her tee shot into the water as Feng birdied the 11th in the group ahead, the gap was down to just three shots heading into the toughest part of the course.
However, Park quickly regained her composure and birdies on the 13th, 15th and 17th sealed victory.
