Someone in your league is about to offer you Spencer Arrighetti in a trade. They are going to lead with the ERA. You are going to hear the words “historically good start.” Both of those things are technically true and neither of them is the complete picture. This column is the complete picture, and it applies to Arrighetti and five other starters sitting on your leaderboard with ERA figures that are doing the hard work of lying to your face every time you open your lineup.

More than two full months of 2026 data now expose six qualified starters whose surface ERAs are running well ahead of what the underlying numbers support. Strand rates are elevated league-wide. Early home run rates on fly balls are suppressed. Schedules in April and May have been tilted heavily toward soft opponents. The ERA column has not caught up yet. It will. The sell window is open right now because your league mates are still looking at the ERA column. Once they look at anything else, it closes.
Here are the six names, their specific failure modes, and what you need to do about it this week.
Spencer Arrighetti, HOU (ERA: 1.94, xERA: 4.76, BB/9: 4.8)
To be honest with you about Arrighetti: the stuff is real, the results have been legitimately good, and he has been the only reliable arm in an Astros rotation that otherwise resembles a MASH unit. He is also walking someone every other inning and surviving it. His 14.3 percent walk rate is the ticking timer here. His wOBA allowed is .267 against an xwOBA of .339, a 72-point gap telling you that hitters are getting worse outcomes than the contact quality warrants. He is a 4.76 xERA pitcher in a 1.94 ERA uniform, and at some point those numbers introduce themselves to each other and it is not a pleasant conversation. Trade him while your league mate is still talking about the historic ERA.
If you’d rather hold for another start or two, monitor his walk rate. If it doesn’t improve, the floor will drop eventually.
Bryce Elder, ATL (ERA: 2.50, xERA: 4.15)
Bryce Elder posted a 5.30 ERA last season. His career strikeout rate is 18.9 percent. He is currently at 2.50. The xERA says 4.15. His BABIP is .222. You do not need a calculator for this one.
To his credit, the K rate has jumped to 9.0 per nine innings in 2026, which is a real development worth watching, but an xERA gap of 1.65 runs does not care about your optimism. Elder’s groundball-dependent approach has a narrow margin for error the moment BABIP starts moving toward his career average. If you own him and someone in your league is offering a piece that helps your actual lineup, this is the week to have that conversation.
Eduardo Rodriguez, ARI (ERA: 2.25, xERA: 4.43)
The D-backs are 8-3 in E-Rod’s starts and he enters June at 5-1. His ERA is 2.25. His xERA is 4.43. That is a two-run gap on a pitcher whose chase rate sits at the 38th percentile and whose 18 percent strikeout rate ranks in the 23rd percentile. His whiff rate is below average for a frontline starter. He is a contact-management story on a soft early schedule, and as any D-backs fan will tell you, that schedule gets harder from here. Worth noting: he has already allowed 10 runs over a recent 14.2-inning stretch, and his current ERA of 2.25 reflects the starts before that run more than after it. The gap between perception and reality is still wide enough to sell into. Do it before another ugly start shrinks it further.
Michael McGreevey, STL (ERA: 2.98, xERA: 5.77, hard-hit rate: 41%)
His hard-hit rate is 41 percent. League average is around 34 percent. People are mashing the ball against McGreevey and it is not turning into runs because of sequencing, a .222 BABIP that will not hold, and a Cardinals outfield that has been catching everything. His xwOBA allowed is .368 against an actual wOBA of .291 and his barrel rate of 11.1 percent is in the bottom tier of qualified starters.
The regression has already started – he posted an 8.00 ERA over his two most recent starts before this writing. His season ERA is 2.98 because the first eight weeks were unsustainable. His next eight weeks will not be. Sell the 2.98.
Davis Martin, CWS (ERA: 2.00, xERA: 4.65)
Martin is outperforming his xERA by 2.65 runs and ranks in the bottom ten percent of the league in average exit velocity allowed. The fair version of this entry is more complicated than the others, though: his walk rate has dropped in a real way from 8.0 percent to 4.7 percent, his swing-and-miss rate has spiked, and he has struck out at least seven hitters in four straight starts. Something real has changed with Davis Martin in 2026. The problem is that the xERA gap is still 2.65 runs and his BABIP is .222. The floor has moved up; the ceiling has not moved up enough to justify a 2.00 ERA. He is probably a 3.50 ERA pitcher right now, not a 2.00 one and not a 4.65 one. If you can trade the 2.00 ERA for something that helps your roster, trade the 2.00 ERA.

Carmen Mlodzinski, PIT (ERA: 2.70, xERA: 4.55)
Mlodzinski has been one of the quieter overperformers on this board. His walk rate has climbed, the hard contact against him has been real, but his home run rate has been suppressed and his strand rate has been running well above 80 percent. He gets away with it because the Pirates outfield is solid and the schedule was gentle in April and May. His K-BB percentage of 18 percent is legitimate and worth credit, but an xERA sitting nearly two full runs above his actual ERA is exactly the kind of gap that June schedules close in a hurry. He is available widely enough in most formats that the sell-high window here means trading him in any league where you can get fair value, not dropping him. His peripherals are not bad. His ERA is not staying this good.
The Sell Window
Every pitcher on this list has a current ERA that is doing more marketing work for them than the underlying numbers support. The practical move is to find the manager in your league who is making roster decisions based on the ERA column-there is always one-and treat this list like a shopping guide for what they want to buy.
The window closes the moment any of these pitchers puts up a five-run disaster that the metrics have been predicting for weeks. At that point the price drops fast. You want to be on the selling side of that trade before it happens, not holding the bag while it does.

Questions About Fantasy Baseball and ERA, Answered
Which 2026 fantasy baseball starters are most likely to see ERA regression?
Spencer Arrighetti, Bryce Elder, Eduardo Rodriguez, Michael McGreevey, Davis Martin, and Carmen Mlodzinski all carry xERAs that run two or more runs above their current surface numbers, and at least one of them is going to remind you what regression looks like before the All-Star break.
Why does a low ERA not tell the whole story for fantasy starters in 2026?
Strand rates, suppressed home run rates, and soft early schedules have artificially inflated ERA figures across the board, and the Statcast numbers underneath most of these pitchers are waving red flags that the box score is still pretending not to see.
When is the right time to sell high on an overperforming starter?
The moment you are reading a column explaining why his ERA is fake is approximately the last good moment to sell, so that would be right now.
What does xERA actually measure and why should fantasy managers care?
xERA uses Statcast contact quality data to estimate what a pitcher’s ERA should look like based on the damage hitters are actually doing, and when it is sitting two runs higher than the surface number it is essentially a countdown clock you should be paying close attention to.
Is Davis Martin’s 2026 breakout real or a regression candidate?
The walk rate is down and the strikeout rate is up, which are genuine improvements, but a 2.65-run gap between ERA and xERA paired with a .222 BABIP says you are trading on a mirage and the real number is somewhere closer to 3.50 than 2.00.
Should I drop or trade these six overperforming starters?
Trade them, because somebody in your league will give you real roster value for a 2.00 ERA before the next ugly start arrives and drops the price for everyone.
