The 22-year-old right-hander was called up from Triple-A Worcester to make his major-league debut Tuesday. He got off to a rough start by allowing a solo homer to Dominic Canzone in the first inning before allowing five runs in the second frame, three of which came on a Randy Arozarena home run. Paez went on to allow a run in each of the next two frames before being pulled in the fourth after tossing 87 pitches (55 strikes) and generating eight whiffs. It's not the way the right-hander was hoping his major-league debut would go, and he'll likely head back to the minors if the Red Sox revert to a five-man rotation.

A Rule 5 Draft pick by the White Sox over the winter, Paez was returned to the Red Sox in early April after making three appearances for Chicago. The right-hander spent most of the campaign at Double-A Portland, where he posted a 4.41 ERA, 1.02 WHIP and 56:5 K:BB across 49 innings. He made his last three appearances for Worcester and was dominant while scattering seven hits and posting an 18:2 K:BB across 12.1 frames. Paez will likely be in store for just one start while the Red Sox build in extra rest for Sonny Gray ahead of his next turn through the rotation.
