Did i make a mistake by jamming?

So im playing MTT, 4 max, turbo, progressive KO, micro stakes.

15/30 blinds, 3k effective stacks, im on the BB with 10sJc .

2 limps, i raise 3bb. Pot is 240.
Flop is 9hQc2c
I check, first guy checks, button raises with 3bb. I call, the guy after me folds.
Turn comes up.
9hQc2cKd

I check, Villain puts another 3bbs. Pot is now 420
River comes
9hQc2cKd7s and i jam. He folds.
