Fifth seed Madison Brengle had another day to forget when she was beaten by Jana Cepelova in the first round of the Japan Open
Fifth seed Madison Brengle had another day to forget when she was beaten by Jana Cepelova in the first round of the Japan Open on Monday.
Brengle retired from her opening match at the US Open on home soil due to an arm injury caused by a reaction to a drug test taken before the tournament, a problem she has struggled with on previous occasions.
The world number 50 was unable to put that setback behind her as she went down 6-1 6-4 to unseeded Slovakian Cepelova on day one of the WTA International tournament in Osaka.
Brengle lost over half of the points in her service games and was broken five times to make another early exit.
Eighth seed Kateryna Bondarenko was also ousted at the Utsubo Tennis Center, going down 6-4 7-5 to Louisa Chirico.
Zhang Shuai, seeded six, made it through to round two but was made to work for a 7-4 (7-4) 1-6 6-3 success against wildcard Eri Hozumi.
Christina McHale was the other seed to advance, while Alison Riske, Kurumi Nara and Varvara Lepchenko were also victorious.
