Why was Seabiscuit called a stalker?

Answer 1

Every horse has his own style. Some like to race on turf, some take the lead early in the race, ect. Seabiscuit liked to hang back, just keeping pace with the horses in front of him, 'stalking' them. In the last few lengths before the finish line he would literally explode with speed. While the other jockeys urged their tired mounts toward the finish line, the Biscuit needed very little urging. According to his long-time jockey Red Pollard, the horse actually thrived on humiliating the other horses in the race. He would pull even, look them in the eye, then kick dirt in their faces as he took over the lead.

At his home in California, there was always a problem of finding horses that would work out with Seabiscuit. Some would get depressed being beaten time and again by the cocky little bay. He had a rather rocky begining, it must have been sweet revenge when other horses were made to eat his dust.
