September 25, 1987 was not a great day for the Orioles. Playing out the string on their worst season since 1955 (at least until the following year!), they were pummeled at home by the Yankees, 8-4. It was the 90th loss of the year for the O's, with a young Jose Mesa getting throttled for six runs on three hits and five walks in less than two innings. Don Mattingly's grand slam was the catalyst, and rookie lefty Al Leiter earned the win with ten strikeouts in six and two-thirds innings (along with four runs on eight hits and five walks of his own).
