Sixth seeds are aiming to win fourth title of the season this week
The sixth seeds recovered from a second-set dip to move past Italians Simone Bolelli 6-1, 3-6, 10-5 in 76 minutes. Koolhof and Skupski have now won five of the six Match Tie-breaks that they have contested in 2022, demonstrating their fighting qualities.
The Dutch-British pair has tasted great success since they teamed for the first time at the beginning of the year, winning tour-level titles together in Melbourne, Adelaide and Doha.
In a tight clash against Bolelli and Fognini, Koolhof and Skupski hit three aces and won 89 per cent (25/28) of their first-serve points, according to Infosys ATP Stats.
They have dropped just one set this week in Miami and will next face Australian Open champions Thanasi Kokkinakis and Nick Kyrgios or Hubert Hurkacz and John Isner in the final on Sunday.
