The US Open: It’s a Hard Court Life
Throughout the history of the US Open tennis championships, the tournament was traditionally conducted on grass courts. That all changed in 1975 when the court surface was switched over to clay. Three years later, the event changed once again to a hard court surface. The original transition from grass to clay was prompted by player complaints about uneven and soft grass courts previously used for the tournament. The subsequent change to hard court was most likely driven by economics.
