The Griffith talent took a thrilling win in the all-Riverina semi-final at Jim Elphick Tennis Centre on Sunday.

He will take on number three seed Jamie Murrie in the final on Monday after a 6-3 7-5 win over Wagga teenager Leon Hemmings.

The top half of the draw really opened up with top seed Aidan Vaughan was beaten 6-0 6-3 by Douglas Skipper in the third round on Saturday.

However Skipper withdrew with a back injury, giving Lachlan Rowing passage through to the semi-finals, where he was beaten 6-3 3-6 10-7 by the number three seed.

Tournament director Tom Denahy said Skipper was in doubt for the entire tournament with the problem and couldn't continue.

"He beat the top seed but it was just too painful for him to continue," Denahy said.

"Unfortunately he had to pull out with a severe back injury. He was going to withdraw from the tournament a week ago but did end up playing."

In the women's draw the top four seeds are through to the semi-finals.

Canberra trio Sarina Kang, Ashleigh Simes and Alyssa Simoncini all secured their places for the tournament's conclusion.

Simes and Simoncini will play off for one spot in the final while top seed Kang faces Grace Bruce.

Denahy was pleased to see the quality rise to the top.
