On this date in history, for two consecutive years, two fan favorites made their major league debuts.
On September 2, 1980, Mookie Wilson made his debut for the Mets in a road game at Dodger Stadium. He started the game in centerfield and was the lead off hitter. Here's a summary of how he fared that day:
1st inning: Groundout to short
3rd inning: Groundout to short
5th inning: Strikeout (Dave Goltz pitching)
7th inning: Groundout to 2nd / RBI - Wally Backman scored from third
The Dodgers won the game 6 - 5.
On September 2, 1981, Ryne Sandberg made his major league debut for the Philadelphia Phillies. The game was held at Atlanta - Fulton County Stadium against the Braves. Ryne didn't start the game, but came in in the top of the ninth as a pinch runner for catcher Bob Boone. SS Larry Bowa came to bat following the substitution and singled, advancing Ryne to third. Next up was Pete Rose, who also singled and Sandberg scored his first of an eventual 1318 career runs. The Braves ended up winning the game, 3 - 2, in the bottom of the ninth.
So both guys contributed in their first game in the big leagues, one with an RBI and one with a run, just as they continued to do throughout their successful careers.
