It's likely that this photo was taken on the same pitch as the base release. The photo was taken at Candlestick and judging by the blurs in the crowd, it was taken at the same game as the Rick Reuschel card that appeared just two cards before Aguilera in the base release.
Aguilera made only two starts against the Giants in 1987, and only once he went up against Reuschel.
On August 30, 1987, Aguilera carried a 5-1 lead through eight innings. The bottom of the ninth started with a strikeout of Joel Youngblood, then Matt Williams and Bob Brenly both homered making the score 5-3. Jose Uribe then flew out to center, after which Eddie Milner walked. Thus ending Aguilera's night. Roger McDowell came in and induced a ground ball from Chris Speier to end the game.
Reuschel didn't fare nearly as well, lasting only a third of an inning, giving up all five Mets runs. It was his shortest outing of the season and only his second start after being traded to the Giants from the Pirates.
Aguilera will be remembered by history as a very good closer. As of the end of the 2008 season, his 318 saves are good for 15th all time. But before becoming a closer, Aguilera was a good starter, going 31-17 in his first three seasons.
He was used as a starter again in 1996 during his second stint with the Twins, going 8-6.
In 1991, Rick saved 42 games and pitched very well against the Braves in the World Series. In four appearances he went 1-1 with a 1.80 ERA and two saves.
