Centerfielder David DeJesus face-planted on the Wrigley warning track in a vain chase for a fly ball against the Diamondbacks last Saturday.

In 1990, eight months after Secretariat died, longtime SI writer William Nack wrote a moving tribute to the greatest horse he ever saw, excerpted here.

The Derby and Preakness had wound him as tight as a watch, and he seemed about to burst out of his coat. I had no idea what to expect that day in the Belmont, with him going a mile and a half, but I sensed we would see more of him than we had ever seen before. Secretariat ran flat into legend, started running right out of the gate and never stopped.... He dashed to the three-quarter pole in 1:094/5, the fastest six-furlong clocking in Belmont history. I dropped my head and cursed Turcotte: What is he thinking about? Has he lost his mind? ... Halfway around the turn, he was 14 [lengths] in front ... 15 ... 16 ... 17. Belmont Park began to shake. The whole place was on its feet.... He opened his lead to 25 ... 26 ... 27 ... 28. As rhythmic as a rocking horse, he never missed a beat. I remember seeing Turcotte look over to the timer, and I looked over too. It was blinking 2:19, 2:20. The record was 2:263/5. Turcotte scrubbed on the colt, opening 30 lengths, finally 31. The clock flashed crazily: 2:22 ... 2:23. The place was one long, deafening roar. The colt seemed to dive for the finish, snipping it clean at 2:24. I bolted up the press box stairs with exultant shouts and there yielded a part of myself to that horse forever.
