At the 1994 U.S. Women's Open at Indianwood Golf & Country Club, Michigan, Alfredsson shot an 8 under first round 63, a new tournament single round record. Her 36-hole total 132 also broke the tournament record. When she reached 13 under during the third round, it was at the time the lowest score to par ever reached in a U.S. Open, by men or women. After playing her last 29 holes in 14 over par, she fell to tied 9th, eight shots behind winner Patty Sheehan.
