Higdon has scored 24 goals this season and the Motherwell striker was nominated for the PFA Scotland player of the year along with Niall McGinn of Aberdeen, Hibernian's Leigh Griffiths and Andrew Shinnie from Inverness Caley.
It took a few months for some Motherwell fans to appreciate Higdon's attributes after he arrived from St Mirren in the summer of 2011 but he is now the holder of the club post-war record for league goals.
Hammell said: "I'm delighted for big Higgy. I think he deserves it. The goals he has scored have been excellent.
"We have players who can create chances but he tucks them away and makes it look easy. He has been scoring all kinds of goals - the two he scored up at Tannadice last week were excellent.
"He has shown great character. It was only a small minority of fans but you could hear them at games and you could see it was getting to him.
"But he slowly turned it around and he has been scoring goals for fun this season. He has come back from being someone who gets a little bit of stick to someone who is one of the fans' favourites, so fair play to him."
