A broken heart probably led to the pastern injury....let's face it...Bluegarss Cat was a game horse thought fought to the wire like all of the good Storm Cats do and he was probably over-extending himself when Bernardini broke his heart at the top of the stretch when he tried him with everything he had twice and couldn't get Bernardini to break a sweat...BGC was all racehorse and you gotta love his competitiveness....thats what makes the good Storm Cats so damn good...they are all fighters
