Berrettini, who reached a career-high ranking of 37 after winning the Hungarian Open last month, can win a third career ATP title in Munich.

The 23-year-old Italian will face fellow surprise package Cristian Garin in the final on Sunday afternoon (1330 GMT), playing back-to-back matches after his semi-final was postponed due to rain.

Chilean Garin upset world number three Alexander Zverev and third seed Marco Cecchinato on his way to the final.
