Ober is a sell — his xERA is a run above league with no luck to blame.

His expected ERA is 4.50, which is .40 above the league average of 4.10, and his sample of 535 batters faced is well past the point where that number becomes reliable. He is not giving runs back through bad luck either. His xwOBA allowed is .325 against a league average of .315, which is worse than average but not the kind of gap that screams bad bounces. The real problem is that he strikes out only 17% of batters and his walk rate is 6.7%, so he has neither a strikeout carry nor a walk-suppression edge to lean on. His fastball averages 88 mph, six miles below league, and the xERA has been stepping up across the season. This is not a pitcher being let down by his defense. Sell. 0 K and a 4.36 ERA ROS: a drop, not a hold — fade the name.
