WATERLOO, Ontario – Sandra Changkija birdied six of her final eight holes for a career-best 8-under-par 63 and a three-stroke lead during the suspended first round of the inaugural Manulife Financial LPGA Classic.

Play was suspended at 4:20 p.m. because of the threat of lightning in the area, and called off for the rest of the day at 6:30 p.m. Seventy-two players were unable to finish the round.

Changkija, making her eighth start in her rookie season, parred her first six holes after beginning play on No. 10, then birdied Nos. 16 and 18. With the wind picking up on the Grey Silo course, she birdied No. 2 and Nos. 4-8 for a front-nine 30.
