Grant said: "I can't hide it, I'm very grateful to receive this award. I'm thankful to the boys for taking the time to vote for me and for all their hard work and endeavour.
"It shows that I'm doing something right. To win last year was unbelievable and to do it again is just unthinkable.
"Consistency has been the buzz word for me this season. I was a little apprehensive about going into this season - more than any other really about being able to keep things going - so to pick this award up is amazing."
