Pete Alonso, affectionately known as the Polar Bear, is once again asserting his dominance in the National League with a fearsome combination of power, plate discipline, and consistency. As 2025 unfolds, Alonso has positioned himself as the king of OPS, a critical stat that merges on-base percentage (OBP) and slugging percentage (SLG)—giving a fuller picture of a hitter’s offensive value.

But what’s truly behind this surge? Is it a mechanical tweak, a mindset shift, better lineup protection, or simply a continuation of the elite slugger he’s always been?

Let’s explore why Pete Alonso is not just hitting well—but dominating.

What is OPS and Why It Matters for Alonso

To appreciate Pete Alonso’s 2025 brilliance, we must first understand OPS (On-base Plus Slugging). It’s the sum of a hitter’s ability to get on base (OBP) and hit for power (SLG). The league average OPS generally sits around .720–.750. Alonso? He’s hovering above .980 in 2025.

That puts him in the elite category—alongside names like Ronald Acuña Jr., Juan Soto, and Shohei Ohtani.

Why OPS Matters for Alonso:

It highlights both patience and power.

It rewards hitters who can change the game with one swing.

It captures impact beyond just batting average.

In Alonso’s case, it’s the perfect stat to measure his value, as he isn’t a high-average hitter, but his walk rate and slugging power are game-changing.

Pete Alonso’s 2025 Numbers Speak Volumes

Through the first 40 games of the 2025 season, Alonso leads the National League in:

Home runs

Slugging percentage

OPS

RBIs

He’s hitting .279/.388/.598 with 14 home runs and 36 RBIs. His OPS? A blistering .986—well above most sluggers and even MVP favorites.

Compare this to his 2019 Rookie of the Year season:

.260/.358/.583 with a .941 OPS

And his 2022 All-Star run:

.271/.352/.518 with an .870 OPS

Clearly, Alonso’s 2025 surge isn’t just good—it might be his best stretch of baseball yet.

Mechanical Adjustments Fueling the Surge

Baseball is a game of constant evolution, and Alonso is no exception. Reports from Mets hitting coach Jeremy Barnes indicate Alonso made a few subtle mechanical adjustments in the offseason:

Shorter swing path: Alonso has eliminated some of the length in his swing, especially on two-strike counts. This has reduced whiffs and improved hard-hit rates.

Better balance: He’s not lunging as much at breaking balls. His improved core strength is keeping him centered.

More compact load: Alonso’s pre-swing setup is more efficient, allowing him to stay back longer on off-speed pitches.

The result? Career-high contact rate and more barrels per plate appearance.

Pitchers can no longer simply throw breaking balls away or try to jam him with high heat. Alonso is adjusting pitch-to-pitch and proving he can crush both mistakes and quality pitches.

The Power Surge: Not Just Home Runs

Sure, Alonso hits moonshots. But what makes him elite is the consistency in hard contact.

Hard-hit rate: Among the top 5 in the NL.

Exit velocity: Averaging over 92 mph.

Barrel rate: At career-high levels.

He’s no longer just a three-true-outcome slugger (home run, walk, strikeout). In 2025, Alonso is also lacing doubles to the gap, driving in runners with line drives, and forcing pitchers to fear him in every count.

His ability to hit the ball hard to all fields has elevated his OPS and made him nearly unpitchable when hot.

Plate Discipline: Alonso’s Underrated Skill

What’s often overlooked is Alonso’s elite eye at the plate. He’s walking more and chasing less.

In 2025:

Walk rate: 13.5% (career-high)

Chase rate: Down to 24%

Strikeout rate: Reduced from 26% to 20%

This improved discipline has boosted his on-base percentage, which plays a huge role in his OPS dominance.

Pitchers who try to work around him now pay the price—either by walking him or by eventually throwing a hittable pitch.

Lineup Protection and Team Impact

Another factor fueling Alonso’s OPS crown is improved lineup protection. With Francisco Lindor rebounding, Starling Marte healthy, and Brandon Nimmo constantly on base, Alonso is:

Getting more pitches to hit.

Coming to bat with more runners on.

Seeing fewer intentional walks or workarounds.

The Mets offense, though inconsistent, has provided Alonso just enough support for him to do serious damage. And when he’s locked in, the whole team’s morale lifts. Opposing pitchers can’t pitch around him like they could in past years.

MVP-Level Production: Can Alonso Win?

While OPS isn’t the only MVP metric, it’s a crucial one. Alonso is currently a top-3 candidate in the NL MVP conversation. His case is built on:

League-leading power numbers.

OPS dominance.

Improved plate discipline.

Clutch hitting (several game-winning hits).

If he continues at this pace and the Mets stay in contention, Alonso could become the first Mets MVP since Keith Hernandez in 1986.

He’s no longer just a home run derby king—he’s a complete hitter.

The Polar Bear Persona and Mental Growth

Nicknamed the Polar Bear for his brute strength and calm demeanor, Alonso has matured both mentally and emotionally in 2025. Teammates and coaches rave about his:

Leadership in the clubhouse

Work ethic off the field

Ability to stay even-keeled in slumps

He’s not chasing numbers. He’s chasing wins.

And that focus may be what’s powering the best OPS of his career.

How Alonso Stacks Up Historically

Here’s a look at some NL sluggers in history who dominated OPS:

Barry Bonds (1.422 in 2004)

Albert Pujols (1.101 in 2008)

Bryce Harper (1.044 in 2021)

While Alonso isn’t touching Bonds territory (no one likely ever will), he’s tracking in the .980 to 1.000 OPS range, which puts him in rarefied air.

If he maintains this through the season, 2025 could be seen as Alonso’s career year—comparable to the best seasons by sluggers over the last two decades.

What Opposing Pitchers Are Saying

When rival pitchers were asked about Alonso’s 2025 performance, the feedback was unanimous:

“You can’t make a mistake. He’ll hit it 450 feet.”
“He’s not chasing like he used to. You have to earn every out.”
“He’s the most dangerous hitter in the NL right now.”

Scouting reports now label him as “hot zone everywhere” and “must-pitch backward,” meaning pitchers have to be extremely creative—and even then, Alonso is making them pay.

The Road Ahead: Can He Sustain This?

Maintaining a near-1.000 OPS over 162 games is no small task. But Alonso’s approach in 2025 suggests it’s not a fluke:

His metrics are stable.

His swing is clean and repeatable.

His discipline is elite.

Health permitting, Pete Alonso could very well finish the season as the OPS leader in the National League—and maybe all of baseball.

More than that, he’s making a strong case to be remembered not just as a power hitter—but as a true offensive force who evolved into a perennial MVP threat.

Final Thoughts: The Polar Bear Is Here to Reign

Pete Alonso’s 2025 campaign is a masterclass in combining power, patience, and poise. He isn’t just mashing home runs—he’s putting together elite at-bats, getting on base, and producing in the biggest moments. His climb to the top of the OPS leaderboard is no accident.

It’s the result of hard work, refined mechanics, mental toughness, and a commitment to becoming more than just a slugger.

As the season heats up, one thing is clear: The Polar Bear sits comfortably on his OPS throne, and it may take a historic effort to knock him off.
