There are many times in harness racing that the front runner gets passed in the stretch and the driver gives up and ends up blowing 2nd or 3rd. You rarely see a driver called in for that. I've seen the top drivers do it all the time including John Campbell, but nothing is ever said. It also happens when the horse sitting in the pocket comes out in the stretch to go after the front runner but after it's pretty obvious, he's not going to catch him, the driver gives up with 20 or 30 yards to go and ends up getting beat for 2nd. In some people's minds both examples could be considered race fixing, but you rarely see a driver get days for lack of effort.
