“I felt great on the court today, I’m really happy with how it went,” said the South Tyrolean after beating Medvedev 6-1, 6-2 in 69 minutes of play.
“He made a lot of mistakes and I took advantage of them,” he added.
“I expected a very tough match and had he broken me early on it would have been different.
“We’ll see how it goes on Sunday,” continued Sinner of the final against Bulgaria’s Grigor Dimitrov.
Last year, Sinner lost to Medvedev in the Miami final 7-5 6-3.
However, on the eve of his second final in the Florida city the Italian said he now feels “a very different player and a very different person”.
“The night before [the final], I couldn’t sleep,” he revealed.
“Now, I handle these situations better and I hope to play well.
“If I win, great. If not, I will have other opportunities.”
