Muguruza: Becoming world No. 1 'a dream come true'

When the next batch of WTA rankings are rolled out on Monday, Garbine Muguruza will become the 24th woman to hold the mantle of world No. 1 since the advent of the computerized rankings in 1975.

Despite losing to Petra Kvitova in the fourth round of the US Open, the 23-year-old Spaniard will take over the top spot from Karolina Pliskova, who failed to defend her finalist points from last year when she lost to CoCo Vandeweghe in the quarterfinals on Wednesday.

"I'm very excited to share with all of you my dream of becoming the next world No. 1 on Monday," Muguruza told the world in a Twitter video following Pliskova's loss. "I would never be in this position without the help of my family, my team, and my fans. Like I said before, it's like a dream come true, so hopefully I can keep this up as long as possible."

Muguruza started her climb this summer at Wimbledon, which she entered as the 15th-ranked player in the world.

After winning the title at the All England Club, she made hay on the summer hard courts, making the semifinals in Stanford and the quarters in Toronto, winning Cincinnati, and making the second week in New York for the first time to complete her ascent to the top of the ladder.

She'll be just the second Spanish woman to hold the No. 1 ranking, and the first since Arantxa Sanchez Vicario in June of 1995.
