Not sure what happened to my first attempt at reply.
Arlington, yes, a leading district driver takes over. I'm unfamiliar with the usual driving tactics used on the 3-wide (Allebasi?) horse but wouldn't the driver on the fav. been better off to allow the 3-wider to take the death seat and then if another 3-wider came later to pull out?
I have just got back into wagering on the standardbreds after a 35 year'ish abstinence (have kept to the thoroughbreds and rugby only) after having been disillusioned with the bad-old-days. I maintain that the harness races are by far the best spectacle and remember 40 years ago at Harold Park on a Friday night (with all the smells) fondly.
