Red Sox interim manager Chad Tracy said that Bello will be deployed as the bulk reliever behind opening pitcher Jovani Moran in Tuesday's game against Detroit, Mac Cerullo of the Boston Herald reports.
Bello has struggled to work deep into outings in the early going of the 2026 campaign, so the Red Sox are electing to use him out of the bullpen for just the fourth time in his five-year big-league career. Moran is likely to cover just an inning or two before giving way to Bello, who owns a 9.17 ERA and 2.15 WHIP over 17.2 innings across his last four appearances.
