Fourteen of 16 Quarterfinalists at ITF J300 Coffee Bowl from US; Vandromme and Bernet Claim Traralgon J300 Titles, Americans Win Doubles; Australian Open Second Round Singles Concludes with 14 Americans in Action Thursday

Although there are two night matches Wednesday at the Coffee Bowl, the ITF J300 in Costa Rica, the number of all-US quarterfinals Thursday is six, with just two non-Americans advancing in today's second round action.

Tonight's two night matches, which are played outdoors in contrast to the day matches held indoors this year, feature Jack Satterfield[8] and qualifier Gray Kelley and No. 2 seed Jack Secord and wild card Keaton Hance. Hance and Secord were members of November's USA Junior Davis Cup team that won the title; both played No. 2, behind Jack Kennedy, with Hance at that spot throughout the knockout round. 

Ryan Cozad defeated top seed Dante Pagani of Argentina 7-5, 6-4 last night and took out Andrew Johnson 6-4, 6-1 today. Cozad won the J100 in Costa Rica last week.

The boys quarterfinals:

Ryan Cozad v Calvin Baierl[5]

Michael Antonius[Q] v Yannik Alvarez[7](PUR)

Lachlan Gaskell[6] v Yubel Ubri

Satterfield/Kelley v Hance/Secord

The girls quarterfinals:

Katie Rolls[1] v Ligaya Murray

Lucy Oyebog Atang[Q] v Ava Rodriguez

Julieta Pareja[5] v Mariella Thamm[4](GER)

Carrie-Anne Hoo v Capucine Jauffret[2]

The ITF J300 in Traralgon Australia finished Wednesday, with top seed Jeline Vandromme of Belgium and No. 8 seed Henry Bernet of Switzerland taking the singles titles. Vandromme defeated unseeded Ksenia Efremova of France 6-3, 6-1 in the final, while Bernet defeated unseeded Egor Pleshivtsev of Russia 6-2, 6-3.

Kristina and Annika Penickova won their eighth ITF Junior Circuit doubles title, with the No. 3 seeds beating Teodora Kostovic of Serbia and Anamaria Federica Oana of Romania 6-3, 6-2 in the final. 

Top seeds Jagger Leach and Great Britain's Oliver Bonding won the boys doubles title, beating No. 2 seeds Max Exsted and the Czech Republic's Jan Kumstat 6-3, 5-7, 10-4 in the final.

Jacob Lee, the only American in the Australian Open Junior Championships qualifying, won his first round match Wednesday, beating No. 13 seed Kohshi Ishibashi of Japan 7-6(5), 6-3. He will face No. 4 seed Tom Sickenberger of Germany for a place in the main draw Thursday (tonight in the US).  

Again, much respect for Tennis Australia electing to play a full third set in these qualifying matches, which Roland Garros also does. Sadly, that is not the case at Wimbledon or the US Open, where a match tiebreaker often decides who qualifies for the main draw.

Three of the five Americans in Australian Open second round action Wednesday advanced in men's and women's singles, but No. 22 seed Sebastian Korda lost to former University of Illinois All-American Aleks Vukic of Australia. Korda is the first seeded American to lose in the Australian Open this year. Fourteen Americans are on Thursday's schedule:
