A native of Lubbock, Texas, Moore is most remembered for the home run he gave up as an Angel to Dave Henderson in Game 5 of the 1986 American League Championship Series with only one more strike needed to clinch the team's first-ever pennant, allowing the Boston Red Sox to come back and win.
Moore was battling injury at the time of that game, and was never able to remain injury-free following it. After saving only 9 more games in 41 appearances over the next two seasons, Moore was released by the Angels. He signed with the Kansas City Royals for the 1989 season, but played only in the minor leagues before being released in June of that year, ending his 14-year career in baseball.
When Moore came in to shut down the rally, there were two outs and a runner on first base (Rich Gedman, who had been hit by a pitch). The Angels were one strike away from advancing to the World Series. Dave Henderson hit a 2-2 pitch off Moore for a home run, giving the Red Sox a 6-5 lead. The Angels were able to score a run in the bottom of the ninth, pushing the game into extra innings.
The pitch . . . Deep to left and Downing goes back. And it's gone! Unbelievable! You're looking at one for the ages here. Astonishing! Anaheim Stadium was one strike away from turning into Fantasyland! And now the Red Sox lead 6-5! The Red Sox get four runs in the ninth on a pair of two-run homers by Don Baylor and Dave Henderson. -- Al Michaels, ABC-TV.
Moore remained in the game for the Angels; he was able to stifle a 10th inning Red Sox rally by getting Jim Rice to ground into a double play. Nevertheless, the Red Sox were able to score off Moore in the 11th inning via a sacrifice fly by Henderson. The Angels could not score in the bottom of the 11th, and lost the game 7-6.
The defeat still left the Angels with a 3-2 advantage, with two more games to play at Fenway Park. However, the Angels were not able to close it out, losing both games by wide margins, 10-4 and 8-1.
In the public perception, Moore became indelibly associated with the Angels' loss of the pennant, in much the same manner that Bill Buckner became associated with the Red Sox' subsequent loss of the World Series later that year.
Back inside the house, still in the presence of one of his sons, Moore then fatally shot himself.
When he was cut by Kansas City, he'd really been depressed about that. I mean, here he is, the high-life career . . . then all of a sudden, it's gone. He comes back home . . . and the marriage, the family, is all destroyed. I mean, what else does he have left?
