'I was really focused, so sometimes I have these kind of moments where I don't even know what the score is.

'I was in a good mood today and good zone,' she said after defeating Gauff. Here, she conceded three games to Brengle and four to Gauff to extend her winning streak to 14. Her last meetings with Madison Brengle and Coco Gauff were tight two-setters. This week, Swiatek dropped just two games to the Swiss player. Last month, she went three sets against Viktorija Golubic in Doha. Instead, she's simply been even more dominant. But Swiatek has squashed any idea that she might be rattled by it. Rising to World No.1 thanks to the sudden retirement of Ashleigh Barty, and the Australian's consequent removal from the rankings, is an unusual way of taking the top spot. The previous occasions were in 2003 (Clijsters and Jennifer Capriati), 2005 (Clijsters and Maria Sharapova), 2008 (Svetlana Kuznetsova and Jelena Jankovic) and 2015 (Serena Williams and Simona Halep). If both Swiatek and Badosa win Wednesday, it will mark the fifth time since 2001 that two Indian Wells semifinalists have gone on to reach the Miami semifinals as well. Between 1996 (when Indian Wells was upgraded to Tier I status) and 2017, at least one player reached the semifinals of both tournaments every year except 1997, 2004, 20.

Though only three players - Stefanie Graf, Kim Clijsters and Victoria Azarenka - have ever won Indian Wells and Miami back-to-back, consecutive deep runs at the two events aren't that unusual. The Spaniard, who will make her Top 3 debut next week, has also reached the last eight in Miami without dropping a set. Indian Wells semifinalist Paula Badosa has also backed up her deep Californian run in style. The Indian Wells champion has dropped just nine games en route to the Miami quarterfinals - an authoritative way to underline her ascension to World No.1 next week. Pulling off the Sunshine Double may be one of the rarest feats in tennis, but Iga Swiatek has made her mission to complete it look easy so far.
