In 1989, the 1989 Detroit Tigers season collapsed to a 59–103 record, worst in the majors. The franchise then attempted to rebuild using a power-hitting approach, with sluggers Cecil Fielder, Rob Deer and Mickey Tettleton joining Trammell and Whitaker in the lineup (fitting for the team with the most 200+ home run seasons in baseball history). In 1990, Fielder led the American League with 51 home runs (becoming the first player to hit 50 since George Foster (baseball) in 1977, and the first AL player since Roger Maris and Mickey Mantle in 1961), and finished second in the voting for AL MVP. He hit 44 home runs and collected 132 RBI in 1991, again finishing second in the AL MVP balloting. Behind the hitting of Fielder and others, the Tigers improved by 20 wins in 1990 (79-83), and posted a winning record in 1991 (84–78). However, the team lacked quality pitching, despite Bill Gullicksons 20 wins in 1991, and its core of key players began to age, setting the franchise up for decline. Their minor league system was largely barren of talent as well, producing only a few everyday players during the 1990s. Adding insult to injury, the Tigers and radio station WJR announced in December 1990, that they were not renewing the contract of long-time Hall of Fame play-by play announcer Ernie Harwell, and that the 1991 season would be Harwells last with the team. The announcement was met with resounding protests from fans, both in Michigan and around the baseball world.
