Tatsuya Imai To Be Posted November 19th

It was reported last week that right-hander Tatsuya Imai would be posted by the Seibu Lions of Nippon Professional Baseball. His agent Scott Boras met with members of the media today at the general managers meeting and said the posting will become official on November 19th. Ben Nicholson-Smith of Sportsnet was among those to pass it along.

Once the posting becomes official, it will open up a 45-day window for Imai and Boras to negotiate will all 30 major league clubs. Technically, they will have until early January to work something out. It’s probably fair to expect a deal to come together before the holidays, when the hot stove activity tends to slow down.

Imai should garner lots of interest based on his results and also his age. His earned run average in Japan has been 2.34 or lower in three straight seasons now, including a 1.92 mark in 2025. His strikeout rate has ticked up from 24.4% in 2023 to 26.3% last year and 27.8% this year. Meanwhile, his walk rate has dropped from 11.4% to 9.8% to 7% in those years.

He is currently 27 years old, turning 28 in May. Teams have shown that they value that youth. Recent deals for young players like Juan Soto, Vladimir Guerrero Jr. Yoshinobu Yamamoto and Jung Hoo Lee have surged beyond expectations.

Imai won’t have as much earning power as Yamamoto, who secured $325MM over 12 years. Yamamoto was even younger, having just turned 25 when he was posted, and also had the superior track record of performance. Still, Imai should find lots of interest. MLBTR predicted he could secure a $150MM guarantee on a six-year deal.

The signing team will also owe the Lions a posting fee, on top of the guarantee they give Imai. The Lions will get 20% of the contract’s first $25MM, 17.5% of the contract’s next $25MM, and 15% of any money above the $50MM mark. If Imai were to sign a deal matching MLBTR’s $150MM projection, his new team would owe the Lions a $24.375MM posting fee.

The righty has already been connected to the Mets. Jon Heyman of The New York Post reported today that the Yankees will be looking at Imai, as well as Lucas Giolito. The Yanks go into 2026 with their rotation in flux. Due to injuries, it projects to be much different later in the year compared to the end of camp. Gerrit Cole is still recovering from last year’s Tommy John surgery and won’t be ready by Opening Day. Carlos Rodón underwent a procedure to remove loose bodies from his left elbow and is expected to start the year on the injured list as well. Clarke Schmidt had internal brace surgery in July and could rejoin the club in the second half.

With those absences, the Yankees project to start the season with Max Fried, Cam Schlittler, Luis Gil, Will Warren and Allan Winans in the rotation. Adding to that group would be an understandable target. It’s possible that things get tight later in the year as Cole, Rodón and Schmidt get healthy, but other injuries could also pop up along the way.

Giolito should be a far more affordable addition than Imai. MLBTR predicted him for a two-year, $32MM deal. He was once a borderline ace but hasn’t been at that level in a while. His ERA finished near 5.00 in 2022 and 2023. He missed 2024 due to internal brace surgery. He returned in 2025 and posted a 3.41 ERA but with less impressive stuff under the hood. HIs 19.7% strikeout rate was below league average and well below the 33.7% mark he had back in 2020. He also finished the season back on the IL with an elbow issue, though he says that has now passed.

There are plenty of other starting pitchers the Yankees could consider at different price levels. Presumably, their plans in the rotation will depend upon what they do elsewhere. They have to address their outfield, with Cody Bellinger and Trent Grisham having both reached free agency. It’s also possible they look to remake a bullpen that was a source of frustration in 2025.
