Ritchie is a sell — his skill is below league with no luck excuse.

His expected ERA sits at 4.80, a full 0.70 above the league average of 4.10, and he has faced 236 batters — enough for that number to be reliable. There is no bad-luck story protecting him: his expected ERA has been stepping up all season, and his BABIP-against is not unusually low, so the scoreboard is not lying. The xwOBA he allows is .336, .021 above league, also stable. He does not get swings and misses (9.8% swinging-strike rate, below league) and he walks 14% of batters — a walk rate that is 6 points above league and also stable. The fastball velocity is average, so there is no stuff story to hang a comeback on. This is the level he is at right now, and the numbers say it will not improve on its own. Sell. 30 K and a 4.55 ERA won't turn around; streaming-only in deep formats, otherwise a roster drop.
