Jessica Pegula says that she could not have imagined being so comfortable in big Grand Slam matches after sweeping Barbora Krejcikova aside to reach the US Open semi-finals.
The American fourth seed beat former world number two Krejcikova 6-3 6-3 to advance to the last four, where she will face either defending champion Aryna Sabalenka or Marketa Vondrousova.
Czech Krejcikova, a two-time Grand Slam singles champion, represented a dangerous opponent after recovering from a set down and saving eight match points against Taylor Townsend in the previous round.
But an impressive Pegula made serene progress to reach the semi-finals in New York for a second year in a row.
"I feel really comfortable. Its crazy to feel this comfortable on the biggest court in the world with the craziest crowd and the best players.
"Its something that 10 years ago I never thought Id be good at this, but I guess I am."
