Launceston junior Oliver Carswell's fourth main-draw appearance at a national event resulted in defeat, with the 12-year-old going down 6-1 6-1 to Elijah Dikkenberg.
The New South Wales player, who is the seventh seed at the Australian 12-and-under claycourt championships in Canberra, proved too much of a challenge for Launceston Church Grammar School's Carswell despite a strong effort.
Carswell earned a break point as his opponent was serving for the match to take it to at least an extra game but was unable to convert.
