US Open changing hard-court brand for 1st time since 1970s
美网42年来首度更换硬地材质
NEW YORK (AP) — The U.S. Open tennis tournament is changing the brand of its
court surfaces for the first time in more than 40 years.
The U.S. Tennis Association announced Monday it has a five-year agreement for
the Billie Jean King National Tennis Center to use Laykold hard courts made
by Advanced Polymer Technology.
美国网球协会周一(03/23)宣布签署５年合约，将 Billie Jean King 国家网球中心硬地
球场材质更换为 Laykold 。
They replace DecoTurf, the hard-court surface played on at the U.S. Open
since 1978.
此前美网使用的场地材质为 DecoTurf，自 1978 年启用。
Laykold courts have been used at the Miami Open and New York Open and for Fed
Cup matches in the United States.
Laykold 球场目前运用在迈阿密站、纽约站及美国联邦杯赛事中。
（Laykold 官网表示辛辛那堤站也预定自今年启用）
The tennis calendar has been in a near-constant state of flux because of the
coronavirus pandemic, but the U.S. Open is still scheduled to start main-draw
action at Flushing Meadows on Aug. 31.
目前美网仍排定自 08/31 起开打。
