Bello will start Saturday's game against the Rays, Ryan Bass of Rays.tv reports.
Bello will draw another start after tossing five shutout innings against the Angels on Sept. 7 in what had been his first MLB start in three months. The 27-year-old threw 19 pitches in 1.2 innings out of the bullpen during his most recent outing Tuesday, but he should still be stretched out enough to pitch fairly deep into Saturday's contest.
