Dan Evans crashed out in the Australian Open's first qualifying round as the British No6 was beaten in three sets by Japan's James Trotter in Melbourne.
Having had his serve broken in the opening game of the match en route to losing the first set, the same happened to Evans at the beginning of the second.
The 34-year-old hit back by taking the next four games as he claimed set two to bring things level, but Trotter then prevailed again, breaking Evans to go 4-2 up in the third before closing out a 6-4 3-6 6-3 victory.
In the women's qualifiers, Harriet Dart made it safely through to the second round by defeating Lizette Cabrera.
The British No4 triumphed 6-2 7-6 (5) and will now face Cabrera's fellow Australian Taylah Preston in the next round on Tuesday.
British No6 Heather Watson also advanced as she overcame Serbia's Lola Radivojevic in three sets, triumphing 7-5 6-7 (14) 6-2 to set up a clash with American Varvara Lepchenko.
Elsewhere on Monday, Jacob Fearnley's exceptional form has earned him a maiden call-up to Great Britain's Davis Cup squad for their upcoming tie with Japan.
Fearnley was outside the top 500 before he won his first ATP Challenger event in Nottingham in June and followed it up with a string of other titles in 2024 alongside an impressive display against Novak Djokovic in a second-round exit at Wimbledon.
Edinburgh-born Fearnley has risen to 86 in the world as a result of a fine six months and Great Britain Davis Cup captain Leon Smith has selected him in a four-man squad for a first round qualifier with Japan later this month.
British No2 Cameron Norrie, world No126 Billy Harris and doubles Grand Slam champion Neal Skupski complete the line-up for this tie, which will be played at Bourbon Beans Dome in Miki across the weekend of January 31-February 1.
Jack Draper had already confirmed last month he would not feature in this tie after discussions with Smith following a recent hip issue and Fearnley has profited ahead of being involved in next week's Australian Open for the first time.
The call-up of Fearnley could also signal the end of Evans' Davis Cup career after the 34-year-old acknowledged following Great Britain's defeat to Canada in September that it could be time for him to leave the party.
Evans has represented Great Britain in 28 Davis Cup ties but dropped to 160 in the world amid poor form.
