After winning their first-round doubles 6-0, 6-0 Carlos Reid and Mitchell Sizemore upset third seeds Liam Cunliffe and Luke Taplin (North Harbour) 6-2, 6-0 on Wednesday evening.
However, in a heartbreaking quarterfinal, they went down 4-6, 6-4 10-6 to another seeded pair yesterday in Dylan Heap (Canterbury) and Liam Stoica (Auckland) after leading by a set and 4-2 and then by 5-1 in the match tiebreak.
"We just didn't play well enough when it mattered most,'' Reid said.
Sizemore had a big day after a rain delay and beat Charlie Tomlinson (Auckland) 2-6, 6-1, 10-8 to make the semifinal of the main draw consolation, but then lost to top seed Stoica 6-4, 0-6, 10-4. He won more games but again was unable to capitalise when it mattered.
Paddy Ou lost to fourth seed Chris Zhang (Auckland) 2-6, 6-1, 10-8 in yet another tiebreak in the same event.
In the girls' consolation, Rebecca Dellaway (North Otago) beat Amily Suga (North Harbour) 3-6, 6-2, 13-11 and then Amy Galloway (Central) 6-3, 6-4 to make today's final.
Emilia Price (Queenstown) won her consolation quarterfinal 6-4, 6-1 but lost to top seed Tamara Anderson (Central) 14-12 in the match tiebreak after having several chances. Price and her Auckland partner, Holly Stewart, now meet the doubles fourth seeds after a 6-1, 6-1 win.
Josh McDermott (Queenstown) has won four matches in the qualifying consolation to make the final today.
