Fantasy baseball managers spend too much time looking at ERA.
The problem?
ERA often tells you what already happened, not how well a pitcher actually performed.
A bloop hit, poor defense, an untimely home run, or bad sequencing can inflate a pitcher's ERA despite elite underlying performance.
To find pitchers who could outperform their current fantasy value, I filtered qualified pitchers from May 1 through July 2 and sorted them by xFIP —one of the best indicators of future pitching success because it removes much of the noise caused by home run variance while focusing on the outcomes pitchers control.
But I didn't stop there.
I also looked at strikeout rate, walk rate, K-BB%, BABIP, HR/FB%, and Baseball Savant's season-long metrics to determine whether each pitcher's underlying arsenal supported the results.
These five arms consistently checked every box.
Nathan Eovaldi
May 1 – July 2
• 3.56 ERA • 3.11 xFIP • 25.2% K Rate • 5.5% BB Rate • 19.7% K-BB%
Nathan Eovaldi continues to age like one of baseball's most reliable veterans.
Over the past two months, he's quietly paired a 3.56 ERA with an even better 3.11 xFIP, suggesting his underlying performance has actually been stronger than the surface numbers indicate.
The biggest reason is command.
A 5.5% walk rate combined with a 25.2% strikeout rate gives him nearly a 20% K-BB%, one of the strongest marks among qualified pitchers during the sample. Even more encouraging, his 17.2% HR/FB rate sits higher than expected, suggesting a few poorly timed home runs have inflated his ERA.
Baseball Savant reinforces everything FanGraphs shows. Eovaldi ranks in the 93rd percentile in Chase Rate, 90th percentile in Walk Rate and 86th percentile in Whiff Rate while continuing to dominate hitters with one of baseball's best splitters.
Elite command. Elite swing-and-miss ability. Strong underlying metrics.
That's exactly the profile fantasy managers should be buying.
Fantasy Verdict: One of the safest buy-low pitchers in fantasy baseball.
Jacob deGrom
May 1 – July 2
• 4.20 ERA • 3.03 xFIP • 31.1% K Rate • 5.3% BB Rate • 25.8% K-BB%
If you only looked at Jacob deGrom's ERA, you'd probably think he's having a solid—but unspectacular—season.
The underlying metrics tell a completely different story.
Since May 1, deGrom owns a dominant 3.03 xFIP while striking out more than 31% of opposing hitters. Pair that with just a 5.3% walk rate and you get one of the best K-BB% marks in baseball over the sample.
Very few pitchers combine elite strikeout ability with elite command.
deGrom still does.
His Statcast profile backs it up. He ranks in the 96th percentile in Whiff Rate, 93rd percentile in Strikeout Rate, 93rd percentile in Walk Rate and 89th percentile in Fastball Velocity.
When the underlying stuff still grades like an ace, fantasy managers shouldn't let one number scare them away.
Fantasy Verdict: The buying window won't stay open much longer.
Drew Anderson
May 1 – July 2
• 3.53 ERA • 3.10 xFIP • 28.9% K Rate • 9.2% BB Rate • 19.7% K-BB%
Drew Anderson has quietly developed into one of the better analytical breakouts in baseball.
His 3.10 xFIP ranks among the best pitchers over the last two months, supported by nearly a 29% strikeout rate and an excellent 19.7% K-BB%.
Those aren't numbers built on luck.
They're the product of legitimate swing-and-miss stuff.
Savant agrees. Anderson continues generating above-average Chase Rates while limiting barrels and weak contact better than league average. His fastball has played up thanks to excellent extension, and his secondary pitches have generated enough whiffs to keep hitters uncomfortable throughout starts.
The profile isn't flashy.
It's sustainable.
Fantasy Verdict: One of the better under-the-radar trade targets heading into the second half.
Andrew Alvarez
May 1 – July 2
• 3.41 ERA • 2.86 xFIP • 27.6% K Rate • 9.2% BB Rate • 18.4% K-BB%
Andrew Alvarez may be the least recognizable name on this list.
That probably won't last.
Among qualified pitchers since May 1, his 2.86 xFIP ranks among the very best in baseball. He's paired that with a strikeout rate approaching 28%, giving fantasy managers one of the strongest underlying breakout profiles you'll find.
What's impressive is how complete the profile looks.
Rather than relying on one dominant pitch, Alvarez attacks hitters with multiple offerings that consistently generate weak contact while missing enough bats to avoid major damage.
His Statcast page supports the improvement with strong chase numbers, quality off-speed run values and above-average contact suppression.
Sometimes the best fantasy buys aren't the biggest names.
They're the pitchers nobody realizes have already taken the next step.
Fantasy Verdict: One of the highest-upside trade targets available.
Dylan Cease
May 1 – July 2
• 3.12 ERA • 2.71 xFIP • 36.7% K Rate • 11.5% BB Rate • 25.2% K-BB%
Nobody on this list misses bats like Dylan Cease.
His 36.7% strikeout rate over the past two months trails almost nobody in baseball, helping produce an elite 2.71 xFIP despite a walk rate that's still slightly elevated.
That's the thing with Cease.
The walks will always create occasional traffic.
The strikeouts erase it.
Baseball Savant continues to love the arsenal. Cease ranks in the 99th percentile in Strikeout Rate, 97th percentile in Whiff Rate, 98th percentile in Breaking Ball Run Value and 93rd percentile in Fastball Run Value.
Very few pitchers possess this combination of raw stuff and swing-and-miss ability.
If the command improves even slightly, there's another level available.
Fantasy Verdict: One of the highest-ceiling buy-low pitchers in fantasy baseball.
Final Fantasy Takeaway
Fantasy baseball isn't won by reacting to ERA.
It's won by identifying pitchers whose underlying metrics point toward better days before everyone else notices.
Every pitcher on this list owns a lower xFIP than ERA over the past two months while pairing those numbers with elite strikeout ability, strong K-BB%, and Baseball Savant profiles that support continued success.
No single metric predicts future performance perfectly.
But when xFIP, strikeout-minus-walk rate, and Statcast all tell the same story, fantasy managers should pay attention.
By the time the ERA catches up to the underlying performance, the buying window is usually gone.
