He returned to Johnson City for 1988. He hit .230 that year over 64 games. In 1989, at single-A Savannah, he hit just .199 in 91 games. He accumulated seven home runs each season.
In 1990, Belbru played mostly at Hamilton, getting another four games at high-A St. Petersburg. He went 3 for 5, with two runs scored and an RBI in an August game for Hamilton. Overall, he hit .262, with 10 total home runs, ending his career.
