UNIVERSITY PLACE, Wash. (AP) — The waterfront golf course Chambers Bay, which hosted the 2015 U.S. Open to mixed reviews, returned to the USGA rotation this week hosting the Amateur Four-Ball championship. The golf course has undergone significant changes since Jordan Spieth won the title six year ago. The greens were entirely changed from fine fescue grass to the more common poa annua grass in 2018. Competitors at the Amateur Four-Ball raved about the conditions. The USGA is returning in 2022 with the Women’s Amateur, and there remain rumblings of the course being a target for a future Women’s Open. But it remains uncertain if the U.S. Open will ever return.
