American Sebastian Korda, who hit the headlines by reaching the fourth round of Roland Garros in October, has booked a spot in his first ATP Tour final after beating Britain's Cameron Norrie in the Delray Beach Open semi-finals.
Korda, the son of former world No.2 and 1998 Australian Open champion Petr, made his Grand Slam debut at the US Open as a wildcard last year.
"For me the biggest thing was kind of getting my consistency up," said Korda, whose sisters Nelly and Jessica play on the LPGA Tour, the elite women's golf circuit.

"Before I'd kind of missed the balls that I don't miss now. So it's super big for me to be playing these matches and kind of just getting a feel for my body, growing into my body and kind of building myself out both tennis wise and physically."

His run in Paris was ended by his idol Rafa Nadal and despite losing 6-1 6-1 6-2 to the Spaniard Korda says it was a "big step in the right direction" for his career.
Korda ended the 2020 season with his first ATP Challenger Tour title and spent two weeks in training in Las Vegas under former world number one Andre Agassi.
He said he was having "a lot of fun" with his family at the tournament.
"If someone told me that I'd be in the finals of my first ATP event here at the start of the week, I'd be thrilled," he added. "I don't see why not to have a good smile on my face."
