Irish duo Dan Martin and Nicolas Roche maintained their high overall placings on yesterday's 161km fourth stage of the Tour de Suisse to Buochs, with both riders finishing in the main bunch in a big sprint to the line.

Each were classified as finishing in the same time as stage winner Arnaud Demare (FDJ), who triumphed after a three-man break containing Jens Voigt (RadioShack Leopard), Olivier Kaisen (Lotto Belisol) and Robert Vrecer (Euskaltel-Euskadi) were reeled in.

Mathias Frank (BMC Racing Team) continues to lead the general classification, holding a 23-second advantage over Roche's Saxo Tinkoff team-mate Roman Kreuziger (Team Saxo-Tinkoff).

Martin is one minute 12 seconds back in seventh overall, while Roche is two minutes 44 seconds down in 20th. Both will hope to move up before the race ends on Sunday.

The WorldTour event is the duo’s final preparation event before the 2013 Tour de France. The race continues today with a lumpy 176.4km race from Buochs to Leuggern and is certain to be marked by more attacks.
