Berrettini, Ruud seeking first ATP Masters 1000 final After earning his first victory on clay against Rafael Nadal in straight sets on Friday, Alexander Zverev will face another member of the ATP Tour’s clay-court elite in the Mutua Madrid Open semi-finals: Dominic Thiem. The World No. 6 owns a 2-8 ATP Head2Head record against the Austrian and has lost the pair’s four most recent encounters, including a heart-breaking fifth-set tie-break defeat in last year’s US Open final. Thiem also holds a 4-1 advantage on clay, but that lone defeat is key. Three years ago, Zverev completed a dominant week in Madrid with a 6-4, 6-4 final victory against Thiem to win his third ATP Masters 1000 title. Memories of that victory, and the pair’s instant classic in the 2020 US Open final, mean Zverev will walk onto Manolo Santana Stadium on Saturday with all the belief and motivation he will need to reach a second Madrid final.
