Dominguez is a hold — league average and stable across the board.

His expected ERA is 4.26, essentially league average, and he has faced enough batters for that number to be reliable. His xwOBA allowed is .318, a hair above the league average of .315, so the contact he gives up is right at the level you'd expect. His barrel rate allowed is 8.1%, dead-on league, and his strikeout rate of 25.2% is a touch above average. The one number pulling the wrong way is his walk rate: 13.3% against a league average of 8.0%, and that has had enough batters to trust. That is the flaw in an otherwise neutral profile. There is no luck stat inflating or deflating his ERA, nothing unstable to correct. If you own him, keep him. Hold.
