Sproat is a sell — the skill is below league and nothing is masking it.

His expected ERA is 4.91, .81 above the league average of 4.1, and his sample of 414 batters faced is well past the point where that number becomes trustworthy. That xERA has been stepping up across the season, not settling down. The contact he allows backs it: a .339 expected wOBA allowed against a .315 league average, a 43.1% hard-hit rate against 40.0%, and an 8.6% barrel rate against 8.0%. He does miss bats — 24.2% strikeouts, 11.5% swinging strikes, 96.7 mph fastball — but he walks 11.6% of batters, well above the 8.0% league average, and that erases the strikeout edge. There is no suppressed BABIP-against flattering the line and no bad-luck story hiding a better pitcher underneath. This is what he is right now. Sell. 12 K and a 4.63 ERA ROS make him a drop, not a stash — deep-league streaming-only until the skills catch up.
