Elaine Genovese and Kim Cassar made sure of winning a medal yesterday after a straight sets victory over Cypriot duo Marilena Papadopoulo and Ionna Nena-Savva to reach the women's doubles semi-final.
But the men's pair of Matthew Asciak and Daniel Ceross bowed out in the quarter-finals after a controversial 6-4 6-4 defeat to Iceland's Arnar Sigurdsson and Birkir Gunnarson.
Genovese and Cassar dominated their Cypriot opponents to ease to a comfortable 6-1 6-2 win that guarantees them at least a bronze medal as the play-off for third place has been ditched from the programme.
Their opponents today will be Liechtenstein's Marina Novac and Kathinka von Deichmann who were awarded a bye to the semi-finals.
The men's quarter-final involving Asciak and Ceross was overshadowed by a series of disputable calls from the San Marino umpire.
With only one line judge present, some calls from the officials angered the Maltese players.
At one stage towards the end of the second set, MOC president Lino Farrugia Sacco asked the tournament referee to appoint a new umpire but play resumed despite more protests from the Maltese.
The Iceland duo went on to secure victory and set up a semi-final clash against Domenico Vinci and Stefano Galvani, of San Marino.
Earlier in the day, Cassar and Genovese were eliminated from the women's singles competition.
Cassar was no match for top seed Mandy Minella, of Luxembourg, as she slipped to a 6-0 6-2 defeat.
Genovese's run in the tournament was ended by Von Deichmann who beat her 6-2 6-4.
After a disappointing first set, Genovese hit back in the second and led 4-2, 40-0, but she failed to close the game. Von Deichmann seized her chance to win the next three games and the match.
Malta national coach Rob Tarpey was gripped by mixed emotions at the end of play yesterday.
"Kim and Elaine have reached the semi-finals in their first appearance together in GSSE doubles," Tarpey said.
"They know they have a medal now and this should help them to play with more confidence, without pressure."
"I'm disappointed with the way we lost our match in men's doubles," Tarpey added.
"I felt we should have done much better and a place in the semis was well within our reach."
