August 15, 1966, a Monday night affair between the first-place Orioles and ninth-place Red Sox.
Boog's first clout came with two outs and nobody on in the fourth inning, and it broke a scoreless tie between starters Jim Lonborg and Dave McNally. McNally continued blanking Boston until the sixth, when Tony Conigliaro's two-run homer put Boston ahead 2-1. Powell gave the Birds new life with another solo shot off Lonborg in the ninth, ultimately sending the game to extra innings. It stayed tied at two apiece until the eleventh frame. John Wyatt relieved Lonborg and walked Frank Robinson. Brooksie came up next and lined out to right, and then Boog capped his excellent night with a two-run homer, which provided the winning margin as Dick Hall wriggled out of a bases-loaded situation for the save. It was a 4-2 final, with all four Baltimore runs coming via Boog Powell homers. There's a statistic known as Win Probability Added, or WPA - it assigns values to each at-bat in a game. Boog's WPA for this game was 0.920, which essentially means that he was 92% responsible for the O's winning that game! I can certainly see why a feat like that would stick in Jim Palmer's memory.
