TOLEDO, Ohio (Ticker) -- Laura Diaz, seeking her third win of the year, carded a 7-under 64 on Friday to open a two-stroke lead midway through the $1 million Jamie Farr Kroger Classic.

The two-time LPGA champion, who started the day tied for 14th after shooting a first-round 70, completed 36 holes at 8-under 134.

Tour veteran Kris Tschetter is in a three-way tie for second with rookies Beth Bauer and Jeane-Marie Busuttil at 6-under 136.

Australian Karie Webb and Kelli Kuehne are tied for fifth at 137, one stroke ahead of Vicki Goetze-Ackerman and Donna Andrews. Korean Se Ri Pak, a three-time winner here, is among seven players tied for ninth at 139.

First-round leader Rachel Teske struggled to a 2-over 73 and dropped to a tie for 16th at 140.

Fourth on the money list, Diaz is one of only four multiple winners on tour this year, joining Sweden's Annika Sorenstam, Pak and Juli Inkster. She won the Welch's/Circle K Championship in March and the LPGA Corning Classic in late May.

Sorenstam and Inkster, who captured last week's U.S Women's Open, are skipping this event.

Nancy Lopez, who is retiring at the end of the year, gave the crowd a thrill by recording a hole-in-one on the 134-yard sixth hole. Despite the ace, Lopez is 10 shots behind Diaz after posting a 1-under 70.
