Twenty-one Americans in Action Monday on Wimbledon's Opening Day; How Do Former Wimbledon Junior Champions Fare in the Pros? ITF Junior, Pro Circuit Update

The top half of the men's draw and the bottom half of the women's draw kick off this year's Wimbledon Monday, with 21 Americans in action.

I mentioned when the draws came out Friday how lopsided the women's distribution was for Americans, with 16 of the 21 US women in the bottom half, so it will be much busier Monday than on Tuesday, when the other seven American men and five American women will place their first round matches (Tommy Paul withdrew Saturday).

Monday's first round matches featuring Americans:

Sloane Stephens v Petra Kvitova[10](CZE)
Venus Williams[WC] v Mihaela Buzarnescu(ROU)
Madison Keys[23] v Katie Swan[Q]
Sofia Kenin[4] v Xinyu Wang[Q](CHN)
Kristie Ahn[LL] v Heather Watson
Jessica Pegula[22] v Caroline Garcia(FRA)
Lauren Davis v Jodie Burrage[WC](GBR)
Danielle Collins v Polona Hercog(SLO)
Ann Li v Nadia Podoroska(ARG)
Katie Volynets[Q] v Irina-Camelia Begu(ROU)
Alison Riske[28] v Tereza Martincova(CZE)
Claire Liu[Q] v Misaki Doi(JPN)
Shelby Rogers v Samantha Stosur(AUS)
Madison Brengle v Christina McHale
Danielle Lao[Q] v Katie Boulter[WC](GBR)

Frances Tiafoe v Stefanos Tsitsipas[3](GRE)
Mackenzie McDonald[Q] v Karen Khachanov[25](RUS)
