'Thorpedo' as his fans call him, had to settle for silver in the 100m backstroke as teammate Matt Welsh set a Games record of 54.72secs.
Backstroke isn't Thorpe's strong point but it's Welsh's speciality.
The 19-year-old insisted he wasn't disappointed with silver.
"That's my best time," said Thorpe. "That's a good result for me. I'm more than happy to come second."
Meanwhile, James Gibson and Sarah Price both got golds for England.
1-2-3 for England
Price broke a Games record in the women's 200m backstroke.
And it was all three medals for England in the 50m breaststroke for Adam Whitehead, James Gibson and Darren Mew.
But there was controversy in the women's hockey: India were awarded the gold medal over England after officials ruled a disputed golden goal stood in the final.
