Cariappa, mystery spinner he likes to call himself, was confident of being picked at the auction but not for the astronomical amount he eventually attracted from Kolkata Knight Riders.
While the players were being traded at a plush hotel in Bangalore, local boy Cariappa and his family were glued to the television in their small rented accommodation in Bagalugunte.
Come to think of it, such is the world of IPL that Cariappa fetched a bigger price than the likes of Kevin Pietersen (Rs 2 crore), Michael Hussey (Rs 1.5 crore) and current England captain Eoin Morgan (Rs 1.5 crore).
"It is unreal to be honest," said Cariappa, who will rub shoulders with Gautam Gambhir, Morne Morkel and his inspiration Sunil Narine.

"KKR video analyst Srikanth took me to the camp and I was suddenly bowling in the nets to someone like a Gambhir. Wasim Akram (KKR bowling consultant) was there and it was just overwhelming. He (Akram) told me that I was bowling well and I needed to work on my fitness."
Though Cariappa has player under-19 cricket for Karnataka, he only got attention when he took 11 wickets, including Manish Pandey's, in the Karnataka Premier T20 League (KPL).
Cariappa calls the leg-spin his stock ball and likes to mix it up with an odd off-spinner and the straighter one.
Talking more about his background, Cariappa says he started playing with the leather ball at 17 and was an fast-bowling all-rounder before taking up spin.
How do his future plans change post the auction?
"I don't care about the money for now. I hope I get to play for Karnataka soon. My parents have sacrificed a lot for me. With the money I get, I want to buy a house for them," he said before rushing to meet the expected visitors at his humble house.
