Fourth seeds Heidi Boyle and Mark Cordeiro pulled off the first major upset of the Coral Beach Club Invitational tennis tournament yesterday when they ousted the favourite duo of Laverne Stowe and Sam Maybury in straight sets, 6-4, 6-4.

Catching Stowe on an off-day, both Boyle and Cordeiro wouldn?t allow her to hide or Maybury to take the pressure off as they relentlessly kept Stowe in the play.

The match opened with Boyle and Cordeiro breaking Stowe and though she and Maybury roared back to break Boyle in the eighth game to level the match at 4-4, the eventual winners again broke Stowe for the second time, leaving Cordeiro to serve out the first set.

Though the second set started with Maybury holding serve to take a 1-0 lead, they again broke Stowe in the third game for a 2-1 lead.

That was the only break they needed to move through to the final where they will now face the third seeded pair of Gill Butterfield and Mike Curry.

Butterfield and Curry advanced to the final with another upset, this time ousting the second seeded pair of Kelly Holland and David Jenkins 6-2, 7-5.

After dropping the first set, Holland and Jenkins appeared headed for a third set when they broke Butterfield at 15 for a 5-3 lead, but then before a hushed gallery proceeded to lose four straight games, the set and match.

But in the day?s longest contest, Jo Tucker took nearly three hours to defeat veteran doubles player, Barbara Lambert, in the Ladies Singles 40 semi-finals 6-7 (4-7), 7-6 (7-3), 6-2.

Tucker will now face the favoured Laverne Stowe in the final.

Meanwhile, for the first time in several years, every match scheduled for play today will have an air of excitement and suspense, with none considered one-sided, starting with the Men?s 45 singles between Maybury and Earl Leader at 9.00 this morning.
