Emma Raducanu has been managing an ongoing back issue in recent months

Emma Raducanu succumbed to defeat by teenager Maya Joint in an edgy second-round match at Eastbourne.

The 22-year-old lost 4-6 6-1 7-6 (7-4) to the Australian 19-year-old, who secured just the second grass-court win of her career.

Former US Open champion Raducanu rallied from 5-2 down in the deciding set to force a tie-break.

But the out-of-sorts Briton could not make it two comeback victories in as many days, having fought back from a set down in an emotional first-round win on the south coast.
