At this moment you're the only one to be put on notice. Dalbec has been up (5th most rbi's on the team) and down (usually), but he is not why the Sox are losing today--Pivetta and the rest of the lineup are.
For big chunks of the season, the Sox have had no good leadoff hitter, but still won games. Richards and a couple others got hit hard by the Commish's dictum about doctoring up the ball, but the rotation overall has been decent if not great.
Fielding has been erratic, but sometimes it's been pretty decent. The outfield leads MLB in outfield assists. Devers has gotten pretty reliable at 3b. Vazquez and Wong are both good defensive catchers.
