I had to look up the game where Gwynn struck out three times against Welch. It happened on Monday, April 14, 1986. Welch struck out 12 in 9 2/3 innings, but didn't get the decision. The game was tied, 2-2, after nine. Mariano Duncan homered in the top of the 10th to put the Dodgers ahead. Gwynn led off the bottom of the 10th by reaching second on an error by Ken Landreaux, who had just entered the game. Welch retired the next two batters without Gwynn advancing before pinch hitter, John Kruk, singled to tie the game.

In the 11th Bruce Bochy won the game with a pinch hit homer to lead off the inning.

Not only was it the lone game, in which Gwynn struck out three times, but it was the only game in Padre history where they had a pinch hit rbi to tie the game in extra innings and a pinch hit rbi to win it in the following inning.
