Yes. The 1985-87 Cleveland Indians finished 60-102, 84-78, 61-101. They finished first in runs scored in '86, thanks to replacing George Vuckovich with Mel Hall, and major improvements from Pat Tabler, Brook Jacoby, and Julio Franco.
They collapsed the next year, as five regulars (Cory Snyder, Joe Carter, Mel Hall, Tony Bernazard, and Chris Bando) compiled OBPs below .310.
