The Phillies have been circling the Japanese market for a few offseasons now, and while they came up short in the Yoshinobu Yamamoto and Shota Imanaga sweepstakes last winter, their interest in Nippon Professional Baseball (NPB) talent hasn’t cooled. This offseason, a new wave of Japanese stars is exploring the jump to Major League Baseball, and one name drawing attention in Philadelphia is right-hander Tatsuya Imai.
Imai, who’s coming off a dominant season with the Saitama Seibu Lions, has officially been posted and is available to MLB teams. And in a move that caught the eye of Phillies fans on social media, Imai recently followed Zack Wheeler on Instagram - a small gesture, sure, but one that’s fueling plenty of speculation in Philly.
Now, let’s be clear: social media follows don’t sign contracts. But when you pair that with Imai’s recent comments and the Phillies’ ongoing search for rotation depth, there’s a real case to be made that this could be more than just a coincidence.
Imai’s Numbers Speak Loudly
On the mound, Imai brings serious credentials. In 24 starts this past season, he went 10-5 with a sparkling 1.92 ERA and a WHIP of 0.89 over 163 2/3 innings.
He struck out 178 while walking just 45 - numbers that point to both command and swing-and-miss stuff. His fastball sits comfortably in the 93-96 mph range, but he can dial it up to the high 90s when the moment demands.
He pairs that heater with a sharp slider and a changeup that keeps hitters honest. It’s a three-pitch mix that’s already proven effective against NPB hitters and should translate well to MLB lineups.
He’s not just another arm - he’s a potential difference-maker.
Not Interested in the Dodgers? That’s Not Nothing
The Dodgers have become a sort of landing pad for top Japanese talent in recent years, with Shohei Ohtani, Yamamoto, and now Roki Sasaki all choosing L.A. as their MLB home. But Imai?
He’s looking to go a different route. In a recent interview, he made it clear that while he respects the talent in L.A., he’d rather beat them than join them.
“Of course, I’d enjoy playing alongside Ohtani, Yamamoto, and Sasaki,” Imai said. “But winning against a team like that and becoming a world champion would be the most valuable thing in my life. If anything, I'd rather take them down.”
That’s the kind of mentality that fits right in with a city like Philadelphia - competitive, gritty, and never afraid of a challenge.
Culture Shock? Imai’s Looking Forward to It
What might be most intriguing about Imai isn’t just his arm - it’s his mindset. He’s not looking for a soft landing or a comfort zone. In fact, he’s actively seeking the opposite.
“If there were another Japanese player on the same team, I could just ask them about anything, right? But that’s actually not what I’m looking for,” Imai said.
“I want to experience that sense of survival. When I come face-to-face with cultural differences, I want to see how I can overcome them on my own - that’s part of what I’m excited about.”
That’s rare. Many international players understandably seek familiarity to ease the transition. Imai’s embracing the unknown - and that’s a trait that could serve him well in a tough, passionate market like Philadelphia.
The Phillies’ Rotation Picture
Looking ahead to 2026, the Phillies still boast one of the better rotations in the National League. Aaron Nola is locked in.
Zack Wheeler remains the ace. Cristopher Sánchez and Jesús Luzardo round out a strong top four.
But with Ranger Suárez unlikely to return, there’s an open spot - and while Taijuan Walker and top prospect Andrew Painter are expected to compete for it, depth is everything in today’s game. Injuries happen.
Seasons are long. And when October rolls around, you want as many high-quality arms as possible.
That’s where Imai could slide in. He wouldn’t be asked to carry the rotation - he’d be complementing it. And with his stuff, his experience, and his mentality, he could be a serious asset in a postseason push.
The Clock Is Ticking
Imai has until January 2 at 5 p.m. ET to sign with an MLB club.
If he doesn’t ink a deal by then, he’ll return to Japan for the 2026 season. But make no mistake - he’s a name to watch.
And if the Phillies are serious about adding international talent and bolstering their rotation, they’d be wise to make a strong push.
Whether it’s a social media breadcrumb or something more, Imai’s connection to Wheeler - and his stated desire to challenge himself on and off the field - makes the Phillies a compelling potential landing spot.
Stay tuned. The offseason just got a little more interesting in Philly.
