Defending champion Daniil Medvedev stormed into the final of the season-ending ATP Finals tournament in Turin on Saturday after crushing Norway's Casper Ruud 6-4, 6-2.
Russian Medvedev will face either Novak Djokovic or Germany's Alexander Zverev in Sunday's final.
Medvedev started strongly against Ruud, breaking early to take a 2-1 lead in the first set and dictating play from the back of the court as Ruud struggled to contend with his opponent's deep groundstrokes.
The Russian won 85% of his first-serve points as he wrapped up the opener in 42 minutes.
The second set followed a similar pattern to the first, with Medvedev racing into a 4-2 lead before closing out the match in 80 minutes, sending down 17 winners and making just 14 unforced errors in the one-sided victory.
The match marked world number two Medvedev's ninth win in a row at the ATP Finals and he improved his head-to-head record over Ruud to 3-0.
