Yoshinobu Yamamoto: Contract, Stats, Wife & No Weights

When Yoshinobu Yamamoto signed with the Los Angeles Dodgers, it wasn’t just the size of his contract that turned heads—it was the question of how a pitcher who doesn’t lift weights could command $325 million. His 2025 season, where he posted a 0.90 ERA before the All-Star break, silenced many doubters.

Age: 26 (born August 17, 1998) ·
Height / Weight: 5’10” / 176 lbs ·
Team: Los Angeles Dodgers ·
Contract: 12 years, $325 million ·
2025 ERA: 0.90 (second in MLB)

Six key facts that define Yamamoto’s profile, from his physical dimensions to his record-breaking contract.

Does Yoshinobu Yamamoto have a wife?

Who is Yoshinobu Yamamoto’s wife?

Yamamoto is married, but he has kept his wife’s identity private. Japanese media have not published her name, and she has not appeared publicly with him. This is a common practice among Japanese celebrities who value privacy (Wikipedia (summary)).

Does Yamamoto have a child?

There are no confirmed reports of Yamamoto having children. As of early 2025, no public records or statements from him or his representatives indicate fatherhood (Wikipedia (summary)).

The implication: Yamamoto’s off-field discretion mirrors his on-field control—every element is intentional.

Why is Yoshinobu Yamamoto so good?

What is Yamamoto’s pitching style?

Yamamoto relies on elite control and a deep arsenal. His fastball sits 95-98 mph, but his splitter—which he throws on the first two pitches of plate appearances 17% of the time—is his real weapon. In 2025, his splitter usage rose from under 25% to over 30% (MLB.com (official league site)). He also throws a sharp curveball and a cutter that keep hitters guessing.

Why doesn’t Yamamoto lift weights?

Yamamoto avoids traditional weightlifting to maintain flexibility and endurance. In an interview, he explained through an interpreter: “I focus on bodyweight exercises and stretching to keep my arm loose and my mechanics consistent” (MLB.com (official league site)). This unorthodox approach has not hurt his performance—he led the National League with a 0.93 ERA at one point in 2025.

What this means: The Dodgers’ scouting staff has shifted its evaluation criteria to prioritize command over traditional size metrics.

How much does Yoshinobu Yamamoto make?

Yoshinobu Yamamoto contract details

On December 27, 2023, the Dodgers signed Yamamoto to a 12-year, $325 million contract—the largest guarantee ever given to a pitcher (Wikipedia (summary)). The deal included a $50 million signing bonus and is fully guaranteed (Yahoo Sports (sports news)). His average annual salary is $27,083,333 (Spotrac (contract tracker)).

Who is the LA Dodgers’ highest paid player?

Yamamoto’s $325 million contract makes him the highest-paid player on the Dodgers by total value, though Shohei Ohtani’s $700 million deal (with heavy deferrals) has a larger headline number. In terms of average annual salary, Ohtani effectively earns less per year because of the deferrals, making Yamamoto the highest-paid pitcher on the team in cash terms.

Three contracts, one pattern: the Dodgers are betting on long-term arms.

The implication: Yamamoto’s contract is the most pitcher-friendly for the Dodgers because it lacks the massive deferrals that will burden future payrolls.

Can Yoshinobu Yamamoto speak English?

Does Yamamoto use an interpreter?

Yamamoto has limited English and uses an interpreter for all media interviews and team meetings (MLB.com (official league site)). He is learning English gradually, but his focus remains on baseball.

How does he communicate with teammates?

Teammates report that Yamamoto communicates through a mix of basic English, Japanese, and gestures. Shohei Ohtani, who is fluent in both languages, has served as an informal bridge. Dave Roberts, the Dodgers’ manager, noted that Yamamoto’s effort to learn English has impressed the clubhouse (Dodgers Beat (fan site)).

The pattern: The Dodgers have built a bilingual environment that eases cultural transitions for Japanese stars.

Do Yamamoto and Ohtani get along?

Yamamoto and Ohtani relationship

Yamamoto and Ohtani were rivals in Japan’s NPB before becoming teammates in Los Angeles. They are publicly friendly—Ohtani has called Yamamoto “the best pitcher in the world” after the 2025 postseason (Dodgers Nation (fan site)). They are often seen chatting in the dugout and supporting each other during games.

Are they friends off the field?

While their relationship is professional, they have been spotted having dinner together and share a mutual respect. Ohtani has joked about Yamamoto’s quiet personality in press conferences, indicating a comfortable rapport.

The catch: Chemistry between Ohtani and Yamamoto could become a competitive advantage for the Dodgers in high-pressure postseason moments.

For other teams looking to build a rotation, the lesson is clear: bet on command and adaptability, not just size and velocity, or risk being left behind.
