"I'm happy but we got more work to do" - Frances Tiafoe reacts to reaching new career-high ranking

American tennis star Frances Tiafoe is having a breakthrough year on the tour. The US Open semifinalist achieved a new career-high ATP Ranking of No.17 after beating Serbia's Miomir Kecmanovic in straight sets in the quarterfinals of the 2022 Rakuten Japan Open on Friday.

In a post-match interview, Tiafoe said that winning was becoming a habit for him. He, however, stressed the need not to be complacent before adding that there was "more work to do."

"Beating the guys you are supposed to beat. That's always been my Achilles heel," revealed Tiafoe. "Winning is more of a habit now - I want more and more. I don't get complacent after winning a couple of matches. I wanna really go deep and play on a lot of Sundays. I'm happy but we got more work to do."

The American added that while he was happy to have attained a new career-high ranking, his main aim was to win the "biggest titles."

"It's cool. My ranking's going in the right direction... The work's finally paying off," he continued. "To be brutally honest, my ranking is cool and everything, but I just want to win the biggest titles in the world. Wherever my ranking sits is great, but I know what I'm capable of."

Tiafoe will square off against Kwon Soon-woo for a place in Sunday's final.
