The Giants forward has been having a superb season in the league and proved a huge asset to coach Jeff Jones’ side.
Jones said: “I’m delighted for Rob. It is a reflection of his ability and the hard work and effort he has brought to the team this year
“He has done a fantastic job and shopuld be proud of his work.”
The 25-year-old has been a huge hit ever since arriving from Leeds Carnegie last summer.
Marsden has played consistently well throughout the season, but has taken his game to another level during the last couple of months as a string of excellent results have pushed the Giants to the edge of the play-off picture.
He did the business for Manchester in a big way during March, with an absolutely superb field goal percentage of 62.7% during his six outings.
He bagged a hugely efficient 15.2 points per game, missed only one of the 15 free-throws he earned and also completed a classy double-double, by hauling down an average of 10 rebounds each time he took to the floor.
Showing his impressive skill-set, Marsden also dished up three assist per game as Giants won four times, only just being edged out by the high-flying Leicester Riders and Newcastle Eagles.
Marsden started March in good form by racking up 15 points and 15 rebounds in an emphatic win against Birmingham Knights. He also top scored in the narrow defeat at the defending champions, as well as firing 23 points in last weekend’s success at Surrey United.
