3/6 - correct river fold?

[giant sand]

I've had a -60BB downswing in last week, and although that's not the end of the world, I would appreciate comments on whether this hand was played correctly.

Crypto site $3-6 6-handed. No reads. Hero is SB with A[img]/images/graemlins/diamond.gif[/img] 10[img]/images/graemlins/heart.gif[/img]

MP1 folds, 3 calls, I call, BB checks.
