Rea is a sell — the contact he allows is below league and getting worse.

His expected ERA is 5.54, a run and a half above the league average of 4.10, and he has faced enough batters for that number to be reliable. The rest of the profile backs it up rather than excusing it. He allows a 42% hard-hit rate and a 10.5% barrel rate, both above league, on a sample of batted balls well past the point where contact quality settles. He strikes out only 17.3% of batters against a 22% league average, and his swinging-strike rate of 9.2% is below league too, so there is no hidden strikeout pitch coming to bail him out. His xERA has been stepping up across the sample. There is no luck story to fall back on; this is the level he is at. Sell. With 10 K, 5.04 ERA and 1.37 WHIP ROS, Rea is a drop — streaming-only fringe, not worth a bench hold.
