On June 4, 1984, Bergman came to bat in the bottom of the 10th inning with two men on base and two outs in a game against the second-place Toronto Blue Jays, who at that time trailed the Tigers by five games. Bergman fouled off seven pitches, and on a full count hit the 13th pitch of the at bat into the upper deck at Tiger Stadium for a walk-off, three-run home run. In his season-long diary that became the book "Bless You Boys", Detroit manager, Sparky Anderson, wrote, "Tonight I saw the greatest at bat in my life...Bergie fouled off seven pitches and then picked one practically off the ground and drilled it into the upper deck in right. What a battle! Bergie was up there a full seven minutes."
