The first team squad took turns to test how hard they could strike a ball after training at Rockliffe Park, with young goalkeeper Connor Ripley topping he scores with an impressive 81mph shot and Argentinian star Emmanuel Ledesma not far behind on 79mph.
And in-form striker Curtis Main showed his potency with both feet, registering 74mph with both his left and his right.
The Boro players finished well ahead of Teesside University students who also tried out the Speed Cage recently when MFC Foundation staff and student volunteers held a fundraiser for the club's charity.
The highest score of the day came from students Andrew Milbourne, Jack Farrell and Craig Wilson, who each clocked an impressive 59mph - a long way behind our pros, who averaged 74mph!
The time and effort put in by the volunteers helped raise over £100 to help the Foundation continue making a real difference.
