On August 10, 1915 — In Washington, Detroit 3B Ossie Vitt is hit by a Walter Johnson fastball and, after being knocked out for five minutes, leaves the game with a concussion. A rattled Johnson then allows four runs in the 1st inning, two runs on a 2-run homer by George Burns, and another four through the 6th inning to lose (he will be 17-2 at home this year). Ty Cobb, observing Johnson’s fear of hitting a batter, will begin to crowd the plate on the Washington ace from here on. Cobb will average .435 for the rest of his career against Walter, after topping .222 only once in the previous eight years.
