Only a stunning last-day collapse can keep Michelle Wie from claiming a spot on the 2009 LPGA Tour after she fired a four-under par 68 in Saturday's fourth round of a qualifying event.

The 19-year-old Korean-American, who must finish in the top 20 to grab a coveted berth on the elite women's golf series, was second on 14-under par 274 after 72 holes in the five-day, 90-hole showdown being played on two courses.

American Stacy Lewis fired a 66 to grab the lead on 16-under 272 followed by Wie and a trio on 275 that included American Mollie Fankhouser, South Korean Amy Yang and Japan's Shiho Oyama.

All of the leaders played the Champions course rather than the harder Legends layout.

The field was trimmed to 70 for Sunday's final round, where 20 spots on next year's tour will be decided.

After four rounds, the top-20 cutoff was at five-under par.

Wie has failed to match her considerable promise since becoming the youngest player to make a cut in an LPGA event, a feat she accomplished at age 13 in the 2003 Nabisco Championship.

Battling a wrist injury, she has endured a disappointing 2008 campaign, missing three cuts and being disqualified from another event in nine LPGA events.
