BOSTON — On a vastly improved pitching staff, Brayan Bello has been the lone Red Sox starter who isn’t pitching to his capability.
His 5.50 ERA is easily the highest in the rotation. His truncated start Tuesday, which lasted just 2.1 innings, the shortest outing by a non-opener this season for Boston. And over the last seven weeks, Bello’s ERA is a bloated 7.49.
