Serena Williams' bid to finally land a record-equalling 24th Grand Slam title may be boosted by the lack of fans at the US Open, says former world number three Pam Shriver.
Williams, 38, has lost her past four major finals when aiming to tie the record set by Margaret Court in 1973.
She lost the past two US Open finals to Naomi Osaka and Bianca Andreescu.
"Without the crowds there, I wouldn't be surprised if she actually feels a little less pressure," said Shriver.
Williams, ranked ninth in the world, will be among the favourites to win in New York when the first Grand Slam since the start of the coronavirus pandemic takes place from 31 August.
