|Career highlights and awards|
Drafted by the Cincinnati Reds in the 9th round of the 1974 MLB amateur draft, Oester made his debut with the Reds on September 10, 1978, and appeared in his final game on October 3, 1990. He finished fourth in the Rookie of the Year voting in 1980. 
Oester was one of the few major leaguers who did not wear batting gloves. He perpetually developed blisters on his hands, and according to teammates, they would develop into deep wounds on his palms.
On July 5, 1987, during a Mets-Reds game at Riverfront Stadium, the New York Mets' Mookie Wilson slid hard into second base during a double-play attempt. During the slide, Oester, who was playing second, collided with Wilson. His cleats got caught in the turf, and he tore his left ACL. Oester did not return to action until July 16, 1988. For his comeback from this injury, Oester earned the Hutch Award.
Oester was a member of the Cincinnati Reds team that defeated the Oakland Athletics in the 1990 World Series. Although he lost the starting second baseman job to Mariano Duncan that season, Oester was one of the team's top pinch hitters, hitting .299 that season and going 2-for-4 (.500) in the postseason. His final major league plate appearance was a hit that drove in Joe Oliver in Game 2 of the 1990 World Series, keeping the Reds in the game, a game they would go on to win in 10 innings.
In 2001, while serving as the Reds third base coach, Oester was offered the job of manager of the club. As the offer was below the market average, Oester turned it down. 
Withrow High School, which Oester attended, renovated and renamed its field in honor of him. 
Oester was inducted into the Cincinnati Reds Hall of Fame in 2014
