Hornstein, a student from Christchurch, went through the interclub season without dropping a set. Most of his wins were by clear margins, and he had the ability to extract the maximum number of errors from his opponents through constant pressure, while making few errors of his own.
He had the chance to go to the United States on a scholarship some years ago, but chose to stay in New Zealand and came to Otago to study. Tennis had taken a background role until this season, when several student friends enticed him to join Cosy Dell club, and he led it to the local championship.
Scott was seen little in Dunedin as she played her interclub tennis in Auckland and then in Christchurch.
But it was her tournament successes in the South which helped her retain the award.
She won the Wanaka Open, the North Otago Open and the Otago Open and dropped very few games in doing so.
She reached the final of the Queenstown Open, and was to play former professional Dianne Hollands, but rain intervened and the title was shared.
Scott's future is in a scholarship in the United States as she follows in the footsteps of Hollands, and Dunedin is unlikely to see much more of her.
Ou racked up 57 matches in a busy season and rose more than 400 ranking points in the national system. He began to beat some more experienced senior players while still only 14.
He lost only one game in four matches in the southern junior team event and made the last eight at the nationals. He was an important part of the McGlashan team that went to the national schools final.
Stevenson also had a busy season and rose 600 points. She also started to overcome experienced senior players.
She won several open junior titles in the region and won several rubbers in easy fashion for St Hilda's in school competitions.
Both Ou and Stevenson will represent Southern at the national junior team event.
