Dodgers Sign Roki Sasaki

Jan. 22: The Dodgers have formally announced Sasaki’s signing. Baseball America, unsurprisingly, ranked Sasaki as the new No. 1 prospect in baseball this morning.

Jan. 17: The Dodgers have landed another star out of Japan. Roki Sasaki announced on Friday evening that he’s signing with Los Angeles. The Wasserman client will reportedly receive a $6.5MM signing bonus. The Dodgers have not officially announced the deal, which can be finalized at any point until the evening of January 23.

As an international amateur, Sasaki is limited to a minor league contract with a hard-capped signing bonus. He won’t immediately occupy a 40-man roster spot, though the team will certainly select him onto the MLB roster by Opening Day. In the end, it’s a fairly unsurprising result, though other outcomes seemed somewhat possible at times. The Dodgers have long been seen as the most logical landing spot for Sasaki, and though the Padres and Blue Jays tried to make surprising runs, the most likely outcome has now come to pass.

Sasaki’s free agency has been hotly anticipated for some time. He made his debut in Japan’s Nippon Professional Baseball in 2021 at the young age of 19 and went on to post outstanding results over the past few years. Thanks to triple-digit velocity on his fastball and a deadly splitter, he has managed to post a 2.10 earned run average in 394 2/3 innings over the past four years. He struck out 32.7% of batters faced and limited walks to a 5.7% clip.

That performance would have made him one of the top free agents of this or any offseason, which normally would have lined him up for a massive payday. However, Sasaki seemed determined to start his major league career as soon as possible, without much regard for money.

If he had waited until he turned 25, he would have been considered a professional under MLB rules, and thus able to sign for any amount the market would bear. That was the route taken by Yoshinobu Yamamoto, who secured a $325MM guarantee from the Dodgers last offseason.

But Sasaki is making the move now, having just turned 23 years old, meaning he is considered an amateur and thus subject to MLB’s international bonus pool system. Under that system, each team gets a set amount to spend on international amateurs annually. This year, each team gets between $5-8MM, a paltry amount compared to what Yamamoto secured. That at least made it theoretically possible that any club could sign him, since the big-spending clubs couldn’t outmuscle the smaller clubs like with many other free agents.

However, despite that theoretical even playing field, there were still many good reasons to expect the Dodgers to emerge victorious. Sasaki and his agent Joel Wolfe didn’t reveal much about the player’s preferences, but logically, the Dodgers are an attractive landing spot. They play on the West Coast, which is often appealing for players coming over from Asia simply due to the relative proximity. They have a strong track record of on-field success, having made the playoffs in each year going back to 2013 now and having just won the World Series a few months ago. They also roster a couple of other Japanese stars in Yamamoto and Shohei Ohtani.

It wasn’t known how much Sasaki would weigh those factors compared to others. Wolfe pushed back on the notion that Sasaki cared about the presence of other Japanese players. He also suggested last month that Sasaki might prefer a smaller market, on account of some friction with the media during his time in Japan.

There were some arguments to possibly consider scenarios where he would prefer to go elsewhere. The Padres could have offered a smaller market than the Dodgers and it was reported that Sasaki has a strong relationship with current Padre Yu Darvish. The Blue Jays are owned by Rogers Communications, the club’s primary broadcaster, potentially giving them the ability to lower Sasaki’s access to the media. The fact that they are the only MLB team in Canada also theoretically opened up more endorsement opportunities from Japanese companies, as opposed to sharing the L.A. market with Ohtani and Yamamoto. The Jays also had a larger international bonus pool than the Dodgers and added to it by acquiring more pool space from the Guardians in a trade earlier today.

But despite any short-term drama that played out this offseason, the most obvious thing has happened. Sasaki has joined a team that is already loaded with stars like Ohtani, Yamamoto, Mookie Betts and Freddie Freeman. 2005 was the last time the Dodgers won fewer than 80 games and now they are adding another hugely talented player into the mix.

Adding Sasaki’s talent is a huge boost to the roster but it’s also massive from a financial point of view. As an amateur, Sasaki will only be able to make the league minimum this year and until he qualifies for arbitration or signs an extension. That’s a massive thing for a club like the Dodgers, who already owe big sums of money to their aforementioned stars as well as Blake Snell, Tyler Glasnow, Teoscar Hernández and plenty of others.

It also gives them an embarrassment of riches in the rotation, at least in terms of pure talent. Their rotation mix now includes Sasaki, Ohtani, Yamamoto, Glasnow, Snell, Tony Gonsolin and Dustin May. It’s a near inevitability that Clayton Kershaw will eventually re-sign. Even with each of Gavin Stone, Emmet Sheehan, Kyle Hurt and River Ryan set to miss most or all of next season, the Dodgers’ rotation should run eight or nine names deep. Landon Knack, Justin Wrobleski, Nick Frasso and formerly touted rookie Bobby Miller are all on hand as depth starters.

It’s a staggering amount of talent for one team. The Dodgers won the World Series last year in spite of their playoff rotation. This year, the rotation should be a strength going into October. That’s despite the injury risk associated with essentially everyone in the group. Glasnow has never surpassed 134 MLB innings in a season. Yamamoto was limited to 18 starts in his first MLB season by a rotator cuff strain. Snell has only topped 130 frames twice. Kershaw, Gonsolin and May all missed most or all of last season recovering from major surgeries. Ohtani underwent elbow surgery late in 2023 and didn’t pitch last year.

Sasaki comes with plenty of durability questions in his own right. He averaged fewer than 100 innings per season over his four years in NPB. He never reached 130 innings and was limited to 111 frames across 18 appearances a year ago. Sasaki had a pair of injuries in 2024: an oblique tear and shoulder fatigue.

The Dodgers will happily take the tradeoff of some IL stints for rate dominance. Los Angeles doesn’t place much value on bulk innings. They’re content to embrace injury risk as they chase pitchers with top-of-the-rotation upside. That’s enabled in part by their resources, of course, though money isn’t a factor for Sasaki.

Every team would have been thrilled to sign Sasaki for $6.5MM. The Dodgers will also owe a $1.3MM posting fee to the pitcher’s NPB team, the Chiba Lotte Marines. The posting fee is proportional to the size of the player’s signing bonus. As Sasaki’s bonus was capped at a few million dollars, the Marines were limited to 20% of whatever he received.

It comes out to a $7.8MM investment to land Japan’s most talented pitcher. The Dodgers have signed arguably NPB’s best pitcher in consecutive offseasons. They’ll have Sasaki for the standard six-year window of team control associated with the promotion of any prospect. He’ll be slated for salaries around the league minimum for the next three seasons. He’d then go through three years of the arbitration process. MLB rules prohibit the Dodgers and Sasaki from reaching any kind of understanding regarding a contract extension to circumvent the bonus pool limits. While there’s no official cutoff for when the Dodgers could look to extend Sasaki, they cannot have any sort of unofficial long-term deal in the works right now.

The Dodgers opened this signing period tied with the Giants for the lowest bonus pool. They had $5.1462MM to spend on international amateurs on January 15. The Dodgers allowed a few of their verbal agreements with teenage prospects to lapse to keep open funds for Sasaki. They added to their pool by dealing minor league outfielder Dylan Campbell to the Phillies and sending outfield prospect Arnaldo Lantigua to Cincinnati tonight. Their precise bonus allotment isn’t known, but Sasaki will take the vast majority of the pool. That’s a trade every team would happily make for a potential plug-and-play ace.

It’s a brutal blow for fans of the other two finalists. The Padres found out this morning that they were out of the mix. They have multiple holes in their rotation and now face an even tougher challenge in the NL West. The Blue Jays finish as the runner-up on yet another marquee free agent talent. Toronto has lost out on Ohtani, Juan Soto, Corbin Burnes and Sasaki (among others) within the past two offseasons alone.
