This first at bat, though, came in the height of a pennant race, his Giants trying to maintain their lead over the division rival Braves. With one swing, Patterson helped them do that, taking a 2-2 ninth-inning tie and turning it into a 3-2 Giants win.
"It's a dream that anybody that plays baseball thinks about. Actually, in my dreams it was with the bases loaded," Patterson told The AP afterward. "But this was just as good."
For Patterson, it was also his first major league home run. In a career that spanned four big league seasons, he would get just four others.
Patterson's professional career began in 1988, taken by the Giants in the 23rd round, out of Grand Canyon University in Phoenix.
Patterson started at short-season Everett, hitting .250 in 58 games. After not being recorded as playing in 1989, Patterson returned to the field for 1990 at San Jose. He hit .302 that year in 131 games. He also knocked in 66 and stole 29.
For 1991, he moved to AA Shreveport, hitting .295 in 117 games, stealing 41. In 1992, Patterson made San Francisco right out of spring.
That spring, Patterson was called a "rookie sensation" by The AP, the switch-hitter Patterson manufacturing the winning run in a spring game.
"I'm just getting good pitches to hit and putting good wood on them," Patterson told The AP after that spring game.
With the Giants in the regular season that year, Patterson got into 32 games, but hit just .184. After his rotator-cuff surgery, Patterson returned for 16 September games. He hit that one home run, but still hit just .188.
Patterson's playing time increased over the next two seasons, to 85 games in 1994 and 95 games in 1995. But they were his final two seasons in the majors. He hit .238 in 1994, then just .205 in 1995.
In one July 1994 game, though, Patterson starred, right along side Giants stalwart Matt Williams. Williams picked up four hits, including a home run. Patterson also picked up four hits in the 14-7 Giants win, scoring three and knocking two doubles.
"It was a big night for Matt," Giants manager Dusty Baker told The AP afterward of Williams, "and an even bigger night for John Patterson."
Patterson is last recorded as playing in 1998, in the minors with Tampa Bay.
