'It's a dream come true. It's amazing,' said Matthew, who collected the first-place check for $112,500. 'I think it hasn't sunk in yet. Ever since I've been out here, I'm trying to win every week. It feels great at last to manage to do it.'
Nancy Scranton, who was tied for the lead with Matthew early on the back nine, was within a stroke with two holes to play but double- bogeyed the 17th hole to fall out of contention. She went on to bogey the last for a two-over 74 and a share of third place at minus-two.
Sorenstam, who also was the runner-up at last week's Takefuji Classic, closed with a two-under 70 to finish alone in second at three-under 213. The 23-time winner pulled to within two strokes of the lead on the front nine Saturday but was never a real threat to Matthew.
'I think I played some good golf,' said Sorenstam, who along with the rest of the field had to contend with howling winds at Kapolei Golf Course, where just eight players broke par for the week. 'It was tough with the wind. Today wasn't as windy, but on some holes it was just tough to tell.'
Matthew had a three-shot lead at seven-under early on Saturday with a birdie at the fourth hole. However, bogeys for Matthew at the sixth and eighth holes together with Scranton's birdie at the seventh saw the pair make the turn tied at five-under par.
Although Matthew missed the fairway with her drive at the par- four 11th, she hit a seven-iron out of the rough from 142 yards out and her ball found the bottom of the cup for an eagle and a lead she wouldn't surrender.
'It's obviously a boost when something like that happens,' Matthew said. 'You start to wonder if it's your week.'
Matthew was tested down the stretch. She hit her tee shot into a bunker at 13 and wound up rolling in a 10-footer to save par. She then posted a bogey at 15 to drop back to six-under when she failed to get up and down after missing the green.
Scranton, only one shot back with two holes remaining, landed in a fairway bunker at the par-five 17th. She played her second shot out to about 100 yards short of the green but flew her approach into the back bunker. From there she blasted out over the green and into a trap on the opposite side. Scranton finally found the putting surface with her fifth shot and two-putted for a double-bogey seven.
Scranton landed her approach pin high at the 18th, but her ball rolled off the back of the green. She chipped and two-putted to close with a bogey.
Danielle Ammaccapane (69) and Wendy Ward (73) finished tied with Scranton at two-under 214.
Michelle McGann (70), Leslie Spalding (70) and Michele Redman (71) were together in sixth place at one-under par. Karrie Webb rounded out the top-10 with five others at even-par 216.
Defending champion Betsy King posted rounds of 75-74-81 to tie for the last spot at 76th.
