Montgomery Reaches Quarterfinals at Las Vegas $25K; Seven US Men Advance to Indian Wells Challenger Quarterfinals; Seven Americans Make Semifinals ITF Grade 3 in Costa Rica

Robin Montgomery hasn't exhibited much rust after taking more than a month off after the Australian Open Junior Championships. The 15-year-old from Washington DC used a Junior Exempt entry for this week's $25,000 Oracle Pro Series tournament in Las Vegas and she has used it well, advancing to the quarterfinals. After beating No. 6 seed Gabriela Ce of Brazil 6-0, 6-2 in the first round Tuesday, Montgomery defeated fellow teen Alycia Parks 6-3, 6-0 today. Montgomery's quarterfinal opponent Emiliana Arango of Colombia, a qualifier, will undoubtedly be exhausted after she needed more than three hours to defeat Ellie Halbauer in a second round match.

ITF World Junior No. 1 Diane Parry of France has advanced to the quarterfinals, where she'll play qualifier Sophie Whittle(Gonzaga). Alexa Glatch is the third American to advance to the quarterfinals, after defeating qualifier Kayla Day 6-2, 6-3.

At the men's $25,000 tournament in Las Vegas, six Americans, all former collegians, have advanced to the quarterfinals. No. 4 seed Martin Redlicki(UCLA) will play No. 8 seed Alex Rybakov and No. 2 seed Alex Sarkissian(Pepperdine) will play No. 5 seed Nick Chappell(TCU). Justin Butsch(LSU), who beat No. 3 seed Jacob Grills of Australia 7-5, 7-5 today, will play wild card Alfredo Perez(Florida). The only two international players are in the top quarter, with Johannes Haerteis of Germany taking on 2018 NCAA champion at Wake Forest Petros Chrysochos of Cyprus, the No. 6 seed.

While six American quarterfinalists is good, seven is better, and that's what the ATP Challenger 125 in Indian Wells will feature Friday. Jack Sock plays Denis Kudla[11], Marcos Giron[14] faces Brandon Nakashima and Steve Johnson[5] meets Noah Rubin. Mitchell Krueger gets No. 9 seed Gregoire Barrere of France, who spoiled a fourth all-US quarterfinal when he defeated No. 8 seed Frances Tiafoe 4-6, 6-2, 7-6(4). With so many Americans left, the second BNP Paribas Open wild card is still up for grabs.

The tournament announced yesterday that Madison Brengle had secured one of the wild cards given out via the Road to Indian Wells competition, and today they announced that Usue Arconada had earned the second, based on her performance in the Oracle Challenger Series events. The only American advancing to the women's WTA 125 quarterfinals in Indian Wells is No. 9 seed Jessica Pegula, who is already in the main draw of the BNP Paribas Open. Pegula defeated Shelby Rogers 7-6(4), 6-2.

An American is assured of winning the boys singles title at the ITF Grade 3 in Costa Rica, with all four semifinalists from the United States. Top seed Max McKennon, who eliminated the only non-US player today, will face No. 5 seed Ozan Colak in the top half and in the bottom half, No. 3 seed Samir Banerjee will play 14-year-old Nishesh Basavareddy. Basvareddy, the 2019 Junior Orange Bowl champion, defeated No. 2 seed Victor Lilov 4-6, 6-2, 6-2 today.

No. 6 seed Nahia Berecoechea of France prevented an all-US girls pair of semifinals, taking out top seed Sofia Rojas 7-6(5), 6-1. Berecoechea will play unseeded Elise Wagle, who beat No. 3 seed Nevena Carton 4-6, 6-3, 6-2. In the bottom half, No. 5 seed Dakota Fordham takes on No. 2 seed Jenna DeFalco.
