If you're a fan of Los Angeles Dodgers pitcher Yoshinobu Yamamoto, you might be wondering about his life off the baseball field. Specifically, you might be asking, "Who is Yoshinobu Yamamoto dating?"
The direct answer is this: Yoshinobu Yamamoto is not publicly dating anyone. He has never confirmed a girlfriend or a public relationship. While there have been a couple of rumors, nothing has been proven true. For now, it seems the star pitcher is mainly focused on his amazing baseball career.

Let's take a closer look at where these rumors started and why they are likely just that—rumors.
The Rumor with Niki Niwa
The biggest rumor about Yamamoto's love life started in late 2024.
What Happened?
During the offseason after his first year with the Dodgers, Yamamoto was spotted in Beverly Hills. A person posted a video on TikTok showing Yamamoto shopping. He was with a famous Japanese influencer and model named Niki Niwa.
Because they were seen together, people on the internet started to wonder if they were a couple.
The Problem with the Rumor
Just being seen with someone doesn't mean they are dating. They could have just been friends hanging out.
Also, a big red flag came later. During the 2025 playoffs, Yamamoto was pitching in very important games for the Dodgers. A report from Sports Illustrated said that Niki Niwa was on a trip with her friends in Hong Kong at the exact same time.
If they were truly boyfriend and girlfriend, wouldn't she want to be at his biggest games to support him? It's possible they are dating and just keeping it very, very private. But it seems more likely that they hung out that one time and are just friends.
The Crazy Sabrina Carpenter Rumor
This is where things get really wild. If you search for "Yoshinobu Yamamoto girlfriend" online, you might see a result that says he is dating pop star Sabrina Carpenter.
Where Did This Come From?
This rumor did not come from a real news site. It started with a single post on X (formerly Twitter) from an account with only 37 followers. The account has a funny name, "Dropped3rdStrike," and it posted a "rumor" as a joke.
The post got millions of views because the idea was so surprising. A famous American pop star and a Japanese baseball pitcher would be a very unexpected couple!
Why It's Definitely Not True
The account that posted it is not a real source for news. It was clearly meant to be a joke or to get a lot of clicks. The post even said it was based on "multiple sources," but with only 37 followers, it has no real sources at all.
While it's a fun idea, there is zero proof that Yoshinobu Yamamoto and Sabrina Carpenter have ever even met. This rumor is 100% false.
Is Yamamoto Focusing on Baseball?
Since there are no real, confirmed stories about a girlfriend, it seems like Yamamoto is choosing to keep his personal life very private. Or, he might just be super focused on baseball right now.
He has already done so much in just two seasons:
He became an All-Star.
He won a World Series in 2024.
He is trying to win another one in 2025.
That takes a lot of hard work and practice. It makes sense that his main focus is on his game.
Learning from Shohei Ohtani
Dodgers fans have learned something important from another star on the team, Shohei Ohtani. Ohtani shocked the world in 2024 when he suddenly announced he was married. Nobody even knew he was dating anyone!
This shows that some players are incredibly good at keeping their private lives secret. So, it is always possible that Yamamoto could be in a relationship that he has not told anyone about. If he is, he's doing a great job of keeping it out of the spotlight.
But until he or someone close to him says something official, we have to go with the facts we have. And the facts say that Yoshinobu Yamamoto is single.
