FORMER Woodhouse Grove pupil Naomi Broady is through to the quarter-finals of a WTA Tour event in New Zealand after winning a controversial clash against Jelena Ostapenko.

The 25-year-old British No 3 not only saved two match points in reeling off six straight games to defeat the Latvian 4-6 7-6 (7/4) 7-5 in the ASB Classic in Auckland but also called for the world No 84 to be disqualified by referee Blaze Trifunovski after Ostapenko threw her racquet in the second set tie-break and it appeared to hit a ball boy.

World No 122 Broady, who notched her first-ever win over a top-20 player in the first round when she beat former world No 1 Ana Ivanovic, looked an unlikely winner when she was broken three times in the opening set and faced her first match point when she trailed 5-2 in the second set.

But saving that inspired an outstanding revival as she claimed four of the next five games to force a tie-break, which she won 7/4 to set up a decider.

The Latvian thought she had the game wrapped up after an impressive start to the third set, but wasted another match point at 5-3, Broady rallying from 5-1 behind to win the next six games for victory.
