Suzann Pettersen is coming off a win in Canada with new coach Butch Harmon and looking for her third major title at the KPMG Women's PGA Championship.

She'll be paired with two-time defending champion Inbee Park and Lexi Thompson on Thursday at the Westchester Country Club. The tournament, run by the PGA of America for the first time, is the second of the LPGA Tour's five major championships.

Top-ranked teenager Lydia Ko joins the field that includes 23 major champions.

Park has had a strong start this season and can return to No. 1 in the world if she wins this week. The South Korean is second on the tour in putting and leads in most rounds under par and top 10 finishes.

The Westchester Country Club was the longtime home of the PGA Tour event now called The Barclays.
