American Roundup: Danielle Collins reaches Chicago's last eight 

Every week, American players from the ATP and WTA tours step up to the plate around the world. Here are the top American movers and shakers that shone brightest this week:

1. Danielle Collins

Quarterfinalist, Chicago Fall Tennis Classic WTA 500 (Chicago)

In the first edition of Chicago's WTA 500 event, Danielle Collins soared into the quarterfinals. Along the way, she took out No. 7 seed Elise Mertens in straight sets to even out the head-to-head record to 1-1.

It was a tough loss to Marketa Vondrousova who fought hard in the third set tiebreak, but the American has a lot to be proud of, reaching eight quarterfinals this season so far.

2. Marcos Giron

Semifinalist, Sofia Open ATP 250 (Sofia, Bulgaria)

Making his first appearance at the Sofia Open, Giron reached the semifinals, losing to the No. 2 seed Gael Monfils. While he couldn’t hold back the Frenchman, the American defeated two other seeded players along the way: Alex de Minaur and John Millman.

3. Coco Vandeweghe and Caroline Dolehide

Doubles Finalists, Chicago Fall Tennis Classic WTA 500 (Chicago)

The two Americans nearly took home the doubles title. Coco Vandeweghe and Caroline Dolehide teamed up and defeated three seeded teams throughout the week. Sadly, the pair could not defeat Andrea Petkovic and Kveta Peschke.

The final marked the first doubles final for Vandeweghe since the 2018 US Open.
