The pilot in the tailwheel-equipped airplane reported that during the landing roll, the airplane veered to the right. The pilot attempted to correct the right veer with left rudder pedal but, "My foot slipped as I attempted to correct." The airplane remained on the runway and ground-looped to the right. The left main landing gear collapsed, and the left wing struck the ground.
The airplane sustained substantial damage to the left wing.
The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
