PACIFIC PALISADES, Calif. – Denise Starr forged her way closer to main draw singles with two wins in qualifying singles on Tuesday at the Riviera/ITA Women's All-American Championships. The California junior needs two more victories to join teammates Maegan Manasse and Klara Fabikova in main draw singles, which begin on Thursday at the Riviera Tennis Club.

The 33rd-ranked Starr – who is seeded ninth-16th in qualifying singles – opened the tournament with a 6-2, 6-2 triumph over USC's 61st-ranked Meredith Xepoleas in the round of 128. She followed that with a win over Mississippi's  57th-ranked Arianne Hartono, 7-6(5), 6-1, in the round of 64. Starr takes on Vanderbilt's 49th-ranked Frances Altick at 11:45 a.m. PT in Wednesday's round of 32.

Along with Manasse, Starr has already claimed a spot in main draw doubles, which also begins on Thursday.

Cal sophomore Karla Popovic also began Tuesday in qualifying singles. But the 64th-ranked Bear fell to Boston College's 90th-ranked Lexi Borr in three sets, 7-5, 4-6, 6-4. Moving to the back draw's round of 32, Popovic defeated New Mexico's Emily Olivier in another three-set match, 6-2, 4-6, 7-5. In the round of 16, Popovic plays Arkansas' 96th-ranked Shannon Hudson at 4 p.m. PT on Wednesday.

Competing in qualifying doubles, Fabikova and Popovic – seeded third and ranked 24th – lost in an upset to Oklahoma State's 36th-ranked Viktoriya Luskova and Carla Tur Mari, 8-1, in the opening round of 32. The Bears next play on Wednesday at 12:30 p.m. PT in the back draw round of 16 against Mississippi's 41st-ranked duo of Natalie Suk and Mai El Kamash.
