Kremer is a sell — the expected ERA sits above league with no luck to blame.

His expected ERA is 4.47, a third of a run above the league average of 4.10, and he has faced enough batters for that number to be reliable. Nothing in the profile is inflated or suppressed by luck. He limits hard contact at a 35.8% clip, better than the 40% league mark, but everything else points the wrong way: a .324 expected wOBA allowed against a .315 league average, and a barrel rate of 9.6% above the 8% league mark. The trajectory says this is not a cold stretch — his xERA has been stepping up across the sample. He strikes out 24% of batters and walks 8.5%, both modestly better than league, but not enough to offset the contact quality. The line is what it is. Sell. 0 K and a 4.34 ERA make him streaming-only; a drop-tier arm no contender should hold.
