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 appearance Tuesday, but he should still be stretched out enough to pitch fairly deep into Saturday's contest.

Bello returned to the rotation for his first start since June 4 and delivered five shutout frames. His biggest test came in the third when Los Angeles loaded the bases with two outs, but Bello retired Moises Ballesteros to escape without damage. The right-hander recorded his seventh career scoreless start, but it remains to be seen whether he'll stay in the rotation since he'd been thriving out of the bullpen as well. Bello owns a 2.03 ERA and 1.03 WHIP over 62 innings as a reliever, yet he's stretched out enough to mix between both roles down the stretch if the Red Sox need him to do so.
