Lexi Thompson has experienced more than her share of heartaches in major championships through the years. She has only win in the LPGA Tour’s Big Five among her 11 career victories, while there are 10 top-four finishes—some of them with the 30-year-old coming excruciatingly close before making crucial mistakes down the stretch on Sunday.

Thompson shot a 2-under 70 Friday to put herself in contention for her first major title in more than a decade.
