As Red Sox Sink, Willson Contreras Is Having the Best Season of His Career

[Yirsandy Rodríguez]

The Boston Red Sox arrived in the Bronx needing answers. They left with more questions.

Following Sunday’s 6–1 loss to the Yankees, the Red Sox now sit at 27–36 and occupy last place in the American League East. They have lost four of five games against New York this season. Still, even in the middle of another difficult afternoon for Boston, one familiar constant stood out: Willson Contreras kept producing.

The veteran first baseman lined a 110-mph RBI double to drive in Boston’s only run. It was far from an ordinary hit. Of the six runs the Red Sox scored across the entire series in New York, four were driven in by Contreras.

And that small sample tells much of the story of his season. While the Red Sox continue searching for collective solutions, Contreras has become one of the team’s few certainties. More than that, he is putting together the best offensive season of his career and, quietly, has placed himself among the best first basemen in Major League Baseball.

When Boston targeted Contreras over the winter, the expectation was stability, experience, and power in the middle of the lineup. What they have gotten is much more than that.

Among first basemen with at least 200 plate appearances, Contreras is firmly in every relevant conversation.

Metric	Value	MLB Rank
wRC+	155	4th
wOBA	.405	T-2nd
xwOBA	.400	T-2nd
OBP	.394	2nd
SLG	.540	4th
WAR	2.2	4th

The only first basemen ahead of him in WAR entering Sunday were Ben Rice, Matt Olson, and Nick Kurtz. That means Contreras has been more valuable overall than names like Freddie Freeman, Bryce Harper, Pete Alonso, Vladimir Guerrero Jr., and Christian Walker.

On its own, that is striking. But in Boston’s context, it is even more significant. A look at the Red Sox offense makes that reality impossible to ignore: Contreras is operating in a completely different tier than the rest of the roster.

Red Sox Offensive Leaders (Entering Week of June 8)

Player	wRC+
Willson Contreras	155
Ceddanne Rafaela	115
Wilyer Abreu	113
Nick Sogard	102
Mickey Gasper	104
Connor Wong	99
Roman Anthony	93
Jarren Duran	84

The gap between Contreras and Boston’s second-best regular hitter is 40 points of wRC+. That is massive. Even more revealing are the offensive metrics that best capture run creation.

Player	OBP	SLG	wOBA
Willson Contreras	.394	.540	.405
Ceddanne Rafaela	.345	.431	.345
Wilyer Abreu	.346	.430	.342
Jarren Duran	.278	.401	.299

No other Sox hitter is even close to those numbers. While much of the lineup has gone through ups and downs, Contreras has maintained consistent, All-Star level production.

That helps explain why he comfortably leads the team in offensive value.

Player	FanGraphs Offensive Runs (Off)
Willson Contreras	15.3
Ceddanne Rafaela	3.9
Wilyer Abreu	3.3
Jarren Duran	-2.1

Contreras has generated nearly four times the offensive value of any other Boston hitter. That is not a normal gap — it is the kind that usually exists between a star and the rest of the roster.

The most interesting part: it is not about better discipline. When a 34-year-old produces the best offensive season of his career, the usual explanation points to improved pitch selection or better plate discipline. But the numbers tell a different story.

Contreras is not chasing fewer pitches outside the strike zone. In fact, he is swinging at more pitches outside the zone than last year. He is also striking out slightly more. On the surface, that should be a negative trend. But what has changed is not how often he swings, it is what happens when he makes contact.

Let's look at this graph showing the average exit speeds in different parts of the area:

His average exit velocity across different parts of the zone shows real damage: over 102 mph in the inner lower-outside area, and consistently above 92 mph across all in-zone locations.

That level of impact explains why his barrel rate has climbed to 15.1%, the best mark of his career. His .242 ISO is also his highest in recent seasons. And perhaps most importantly, the expected metrics fully support the results.

Metric	Value
wOBA	.405
xwOBA	.400
SLG	.540
xSLG	.537
Barrel Rate	15.10%
ISO	.242

Perhaps the most telling number is strike rate. In 2025, Contreras saw strikes on 50.8% of pitches. In 2026, that number has dropped to 44.8%. Pitchers are attacking him differently, giving him fewer opportunities to do damage.

He is being shown more respect and he is still producing. That is what happens when a hitter crosses the line between dangerous and unavoidable — someone who forces opposing teams to change their entire approach.

Boston’s first two months of the season have been defined by losses, inconsistency, and unanswered questions.

Willson Contreras’ season has been the opposite. If anyone is keeping this team afloat, it's him.
