As so often happens in tennis, it wasn't Sunday's winners who made the biggest charges in the ATP rankings, but the men who almost got it done.

Open 13 runner-up Marin Cilic improved seven spots to No. 21, and Memphis finalist Milos Raonic leapt 22 places to No. 37 in the rankings released Monday morning.

Raonic has now climbed 116 spots since the start of 2011.

The top 15 places were unchanged, with Mardy Fish and Jo-Wilfried Tsonga changing places at 16 and 17.

Two Americans took steep dives.

Sam Querrey and John Isner fell out of the Top 20. Querrey fell four spots to 22nd, while Isner tumbled eight spots to 32nd, courtesy of his first-round loss to Juan Martin Del Potro in the first round at Memphis after losing in the final to Querrey a year ago.
It's Isner's lowest ranking since he was 33rd on Jan. 11, 2010.

The other big mover in the Top 100 was American Robert Kendrick, who jumped 27 spots from 110th to 83rd. The 31-year-old native of Fresno, California, Kendrick made the quarterfinals at Memphis before losing to Raonic, and improved to 4-3 overall.

Caroline Wozniacki took over No. 1 as expected, but there more changes in the Top 10 this week thanks to strong play from Jelena Jankovic and Samantha Stosur.

Stosur rose to No. 4 in the world, passing Francesca Schiavone by 35 points (5,086-5,051) after reaching the Dubai quarterfinals. She was defeated there by Jankovic, who had her best finish in six months, and was rewarded accordingly, jumping two spots to No. 6, jumping the upset Na Li and the idle Venus Williams.

Wozniacki now has a 595-point lead on Clijsters for the No. 1 spot.  Wozniacki will have the chance to pad her lead this week as she takes part in the WTA Qatar Ladies Open in Doha, a 470-point payout.

Neither will play again until Indian Wells in the second week of March. Wozniacki will have to defend her 700 points from reaching last year's final, while Clijsters has just 80 to protect after being upset in the third round there a year ago.  

The biggest jump in the Top 20 came from Wozniacki's Dubai final opponent, Svetlana Kuznetsova, who jumped 10 spots from 23rd to 13th. It's her highest ranking since early in the 2010 season.

Sliding the other way were Maria Sharapova (13th to 17th), Anastasia Pavlyuchenkova (15th to 19th), Nadai Petrova (20th to 22nd) and Arvane Rezai (23rd to 21st).

Three players jumped at least 20 spots apiece in the Top 100, led by Slovakia's Magdalena Rybarikova, who surged up 38 places from 105th to 67th.  The 22-year-old came out of nowhere to win Memphis, upsetting eighth-seeded Vania King in the first round and carrying it through to the final, where she led 6-2 when sixth-seeded opponent Rebecca Marino retired due to injury.

Spain's Lourdes Dominguez Lino surged 26 spots from 77th to 51st. The 29-year-old Spaniard won at Bogota to gain 280 points as the seventh seed.

Also joining the Top 100 is Petra Martic, who moved up from 119th to 98th. Barely 20 years old, the Croatian native followed up her second-round appearance at the Australian Open with a semifinal performance at Bogota, losing to eventual champion Dominguez Lino after upsetting second-seeded Polona Hercog in the round of 16.
