Despite having to play the entire second-half a man down following Roman Piotrowski's red card, London Scottish beat Richmond in their first derby for two years on Saturday.

Piotrowski, National Three (South)'s top tryscorer,was sent off for stamping, but Scottish still had too much power and pace for their co-tenants at Richmond Athletic Ground.

Only James Brown's penalty for Scottish separated the sides when the Scots were reduced to 14 men, but it seemed to galvanise them more than Richmond.

Soon after,Gareth Swales, who earlier had a try disallowed due to Rory Greenslade-Jones' forward pass, touched down after running 40m unopposed from a ruck.

And Greenslade-Jones atoned for his earlier error on the stroke of half-time by holding off challenges from David West and Matt Hart to score.

Scottish continued where they left off after the break with two more Brown penalty,sandwiching Richmond's opening try.

Ed Rosa darted over after after a beautiful dummy pass from Kris Greene,before Hart added the two points.

Tim Cook ran 70 yards to add a second Richmond try in injury time,but it was too late to prevent a defeat, Scottish winning 21-12.
