Sasha Fisher continued her stampede through the Ladies? A singles event at the Argus Open Tennis Tournament on Monday.

The 18-year-old Blair Academy student demolished her younger rival, 14-year-old Saddlebrook Academy attendee Caitlin Gordon, 6-1, 6-0.

Fisher served with power and precision, continually attacking Gordon?s serve to dominate the match.

Men?s B singles top seed Frank Tersigni continued his winning ways, showing fitness and agility in a 6-1, 6-0 win over Dion Burgess.

In the Men?s A singles John Johnston gave David Jenkins a scare in the second set when he took it 6-3 to square the match after losing the first 6-3.

Jenkins clearly needed to move forward and finish the points at the net but Johnston managed to keep him on the back line.

But in the final set Jenkins worked the kinks out in his game to emerge a 6-3, 3-6, 6-2 winner.

Number six seed Ben Lau pulled off an upset over fourth seed Paul Mosquera in the Men?s B singles quarter-finals in an incredible three-hour, three-set thriller on court three.

Lau hit seemingly effortless deep and flat shots while Mosquera tried to respond with heavy spin.

Mosquera, often on the ground after points, was noticeably getting frustrated with Lau?s persistence and superb returns. Lau chased down at least a dozen overheads, sprinted for drop shots and eventually won the match 5-7,6-2, 6-4.
