Houston Signs Tatsuya Imai… At Least for Now

Troy Taormina-USA TODAY Sports

Yesterday, the New York Post’s Jon Heyman reported that Japanese pitcher Tatsuya Imai has agreed to a three-year, $54 million pact with the Houston Astros (ESPN’s Jesse Rogers had the length). The deal includes opt outs after each of the first two years, essentially a “prove it” contract that gives Imai the opportunity to re-enter free agency should he quickly demonstrate that he’s better than the open market seemed to think he was during this posting period. Speaking of the posting system, note that the Astros will also pay Imai’s Japanese club, the Seibu Lions, just shy of $10 million under the current MLB/NPB posting agreement’s formula (20% of the contract’s first $25 million, 17.5% of the next $25 million, and 15% of anything over $50 million). The deal also features $9 million in escalator clauses that kick in as Imai approaches and crosses the 100-inning threshold during his first two seasons, bringing Houston’s total potential expenditure to roughly $73 million.

This deal is shorter and less lucrative than was generally expected by pundits (including yours truly) when it became known that Imai would be posted; Ben Clemens forecast a five-year, $100 million deal, while our median crowdsource estimate was for four years and $64 million before the posting fee. Imai is 27-years-old, he’s coming off of his best pro season after multiple consecutive years of improved strike-throwing, and he checks several of the visual scouting and data analytics boxes you want from a mid-rotation starter. What could be the reason(s) for the discrepancy between our collective expectations and Imai’s actual payday, and where does he fit into Houston’s rotation?

Let’s revisit the background on Imai. He was the Seibu Lions’ 2016 first round pick out of a high school in Utsunomiya City, a metro roughly the size of Tucson that’s about 80 miles north of Tokyo. He spent a year in the minors and then hopped right into the Lions rotation as a 20-year-old in 2018. Throughout his early and mid-20s, Imai was a walk-prone (but effective) starter. He dealt with multiple ailments in 2022 (including a right adductor injury), then took a step forward as a strike-thrower and an innings-eater in each of the next three seasons, becoming one of NPB’s best arms. Across the 2022-25 seasons, Imai halved his walk rate (from the 14% area to 7%), expanded his repertoire, and improved his fastball velocity even as his innings count grew to north of 160 frames. He’s had four consecutive seasons with an ERA under 2.50 (even while he was wild), and in 2025, he posted a 1.92 ERA and 2.01 FIP. Read the rest of this entry »


Creating a Projection for Munetaka Murakami

Rhona Wise-USA TODAY Sports

What sort of production can we expect from Munetaka Murakami in 2026? This article walks through my steps in creating an MLB projection for the Yakult Swallows superstar.

With one day to go before his negotiation window closed, Murakami and the Chicago White Sox agreed on a two-year, $34 million deal; you can read Michael Baumann’s thoughts on the signing here. Both the dollar amount and the length fall well short of expectations: Ben Clemens projected him to land a seven-year, $154 million contract, while our median crowdsourced contract estimate was for six years and $132 million. Prior to Murakami’s posting, Eric Longenhagen highlighted his 80-grade raw power, as well as his major contact issues, in an October international players update. Both Eric and Ben saw first base as Murakami’s likely defensive home, something the White Sox have already confirmed for the coming season. ZiPS projects him for a .237/.363/.454 triple-slash line and a 126 wRC+. My own projection system, OOPSY, does not yet project NPB players, but that’s something I’m aiming to change with this article. So what might OOPSY expect from Murakami?

The first step in creating a Murakami projection was to review the literature. Previous research from team scouts, analysts, and the creators of other projection system tends to rate NPB as close to Triple-A in terms of its quality of competition. This serves as a good reference point for developing my own quality of competition estimate. Read the rest of this entry »


Let’s Scout the Players Coming Over From Asia

It’s time for another cycle of prospect lists and, as has become customary, we’re starting with scouting reports on pro players in foreign leagues, with a focus on players available for MLB free agency this offseason. On The Board, you can access a fresh batch of scouting reports and evaluations for relevant players from Nippon Professional Baseball, the Korea Baseball Organization, and the Chinese Professional Baseball League in Taiwan, as well as reports on some young players we’ve identified as potentially impactful long-term prospects. For those who need a crash course on the age- and pro experience-driven lines of demarcation that dictate how MLB teams sign international players, we’d point you to a number of MLB.com glossary entries, including those on international free agency for those in Asian pro leagues, international amateur free agency and bonus pool restrictions, the Japanese posting system, and the Korean posting system.

It can be a bit overwhelming to sift through so many different types of players on that section of The Board — it’s a real apples and oranges situation when we’re talking about some guys who are in their 30s and others who are fairly young — so we’ve broken many of them into digestible subgroups below, with focus on the crop that is purported to be coming over this offseason. You’ll notice that some players appear across multiple categories. The Board has each player’s full scouting report and tool grades — think of this as more of a table of contents.

Updating the International Player Rankings

Sam Navarro-USA TODAY Sports

Now that the dust has settled on teams’ pursuit of Roki Sasaki, and clubs have signed most of their 2025 international prospects, it is time to turn our attention to the international pros whose 2025 seasons will soon get underway and to the tippy top of the 2026 international amateur class. All of my top 2025 international prospects have now signed. Twins outfielder Carlos Taveras was the last from that group to put pen to paper, signing a couple of days ago for a shade over $1 million. The players and rankings from that class have been archived on their own page of The Board, including the couple of Japanese pros who came over from NPB this offseason. Remaining on the active International Players page (which you’re going to want to open in a new tab) are the foreign pros I think readers should know about and follow for this season and beyond, as well as a couple of amateur players from the upcoming 2026 class (more on those lads in a few paragraphs).

2024-25 International Pro Prospect Update: Scouting Roki Sasaki and Others

Relentless Dodgers Splash Cash To Add Yamamoto on $325 Million Mega-Deal

Yoshinobu Yamamoto
Yukihito Taguchi-USA TODAY Sports

Late Thursday night, while Shohei Ohtani was awkwardly smiling on the jumbotron at the Rams game in Los Angeles, the Dodgers were wrapping up the details on a massive, 12-year contract for 25-year-old Japanese righty Yoshinobu Yamamoto in the amount of $325 million. The Dodgers will also pay roughly $50 million in posting fees to Yamamoto’s former NPB team, the Orix Buffaloes, making the Dodgers’ total commitment a whopping $375 million, with $50 million of the deal to be paid via signing bonus. ESPN’s Jeff Passan reported that the contract also has two opt-outs, but we don’t yet know when in the deal they occur.

This is a huge deal in several manners of speaking. First, it is literally a huge deal, the largest-ever contract for a pitcher, eking past Gerrit Cole’s $324 million pact from 2019. Between the $700 million guaranteed to Ohtani and the $325 million heading to Yamamoto, the Dodgers have committed well over $1 billion dollars to free agents (spread out over the next decade-plus) already this offseason. For context, in 2019, the Royals sold for $1 billion. The Dodgers’ estimated payroll for 2024 now stands at $285 million, $50 million more than their 2023 mark.

Here are Dan’s ZiPS projections for Yamamoto. He passed along that the projection system would recommend a 12-year, $320 million deal for him.

ZiPS Projection – Yoshinobu Yamamoto
Year W L ERA G GS IP H ER HR BB SO ERA+ WAR
2024 14 7 3.52 26 26 171.3 130 67 22 35 167 118 3.8
2025 14 7 3.54 26 26 170.3 132 67 23 34 166 117 3.8
2026 14 7 3.54 26 26 173.0 135 68 23 33 168 117 3.8
2027 14 7 3.59 27 27 170.7 137 68 24 32 165 116 3.6
2028 14 7 3.69 27 27 170.7 140 70 25 32 163 113 3.4
2029 13 8 3.77 26 26 164.7 139 69 24 32 154 110 3.1
2030 12 8 3.78 24 24 157.3 134 66 23 31 145 110 3.0
2031 12 7 3.83 23 23 150.3 129 64 22 30 137 108 2.8
2032 11 7 3.88 22 22 141.3 123 61 21 29 126 107 2.5
2033 10 7 3.97 21 21 131.3 116 58 20 28 115 105 2.2
2034 9 6 4.15 19 19 121.3 109 56 19 27 104 100 1.8
2035 8 6 4.27 17 17 109.7 101 52 18 26 91 97 1.5

Projections systems like ZiPS tend to flatten and smooth the peaks and valleys of everyone’s performance, so think of this as a projected annual average for Yamamoto’s production. His peak years, which should begin immediately, are likely to be better than the front end of these projections. Read the rest of this entry »


Board Update: International Professional Players

Samurai Japan’s WBC Squad Brings the Best of NPB (and MLB)

Yukihito Taguchi-USA TODAY Sports

Japan has a long history of baseball in its popular culture. From the organized cheers for NPB players and teams to the summer Koshien high school tournament, baseball serves as not just a spectator sport but a way of life for many people. As a result, Japanese players put great emphasis on their national team’s success in international competitions to showcase the country’s best. In recent memory, Samurai Japan has dominated on the international stage, winning each of the first two World Baseball Classics in 2006 and 2009. Daisuke Matsuzaka claimed MVP in both tournaments, winning all six of his decisions, while hitters like Ichiro Suzuki and Kosuke Fukudome led the way offensively. In 2013 and 2017, they reached the semifinals before ultimately being eliminated, but they remain the only team to place in the top four in each iteration of the WBC. More recently, Japan claimed the gold medal at the 2020 Olympics, shutting out the United States in the championship game. Samurai Japan hopes to continue this run of international success, fielding a largely similar group of players from their Olympic title squad.

Much of Japan’s on-base skill comes from the outfield, led by current Red Sox outfielder Masataka Yoshida. Previously a member of the Orix Buffaloes, Yoshida has one of the best combinations of contact skills and plate discipline in recent memory. A two-time batting champion, Yoshida walked twice as much as he struck out over the past three years and just finished his best season to date with a 201 wRC+. While he doesn’t have monster exit velocities, he puts so many balls in play that eventually a good number go over the fence; he has averaged 23 homers over the past five seasons. Yoshida is a bit defensively limited in left field, but he won’t be able to spend time at DH in the WBC like he did with the Buffaloes because a little-known player on the Angels already has claim to that spot.

Another member of Samurai Japan who wears a red MLB uniform is Lars Nootbaar (who might have the coolest middle name of all time). A batted ball data darling, Nootbaar had a great rookie year with the Cardinals, producing plus exit velocities, a refined plate approach, and 2.7 WAR in just 347 plate appearances. Nootbaar will likely play center field for Japan despite being a corner guy in MLB, but his above-average speed and arm strength should make the transition to center relatively smooth. Nootbaar and Yoshida are joined by Kensuke Kondoh (whose Fukuoka Softbank Hawks don’t wear red, unfortunately). While he doesn’t have much thump in his bat, maxing out at 11 homers in a season, his plate discipline makes him one of the most talented offensive players in Japan. He’s consistently run chase rates in the 18-19% range (second best among NPB hitters), and just finished his sixth consecutive season with an OBP of .400 or higher. Read the rest of this entry »


Athletics Bolster Pitching Staff With Ex-NPB Hurler Shintaro Fujinami

Oakland Coliseum
Robert Edwards-USA TODAY Sports

He’s not the Japanese starting pitcher that fans were likely hoping for, but the Athletics signed Shintaro Fujinami to a one-year deal worth $3.25 million, just a couple days before the January 14 deadline to sign posted players. With most starting-caliber players already traded away for prospects, Fujinami becomes just the sixth Oakland player not on a league minimum or arbitration contract, joining a collection of names including fellow international signee Drew Rucinski.

Eleven years ago, when an 18-year old Fujinami was selected in the first round of the 2012 NPB draft by the Hanshin Tigers, many evaluators considered him better than Shohei Ohtani, also taken in that round. Fujinami was well-known as a prospect coming out of high school, where he led his team to victory in the summer Koshien tournament by throwing complete-game shutouts on consecutive days, then tossing another shutout to clinch a junior world championship less than two weeks later. He had an excellent rookie season with the Tigers, posting a 2.75 ERA over 24 starts, and continued this excellence from 2014 to ’16 with a 3.02 ERA and 16.2 WAR, placing in the top seven pitchers by WAR each year.

Then things started to come off the rails. Where Fujinami had succeeded in spite of his below-average command in his first four years, his strike-throwing issues became debilitating after that. In 2017, he walked a sixth of his batters faced; in ’18, his ERA climbed to 5.32 as the walk issues remained. He made just one start in 2019 and has played part of each season since in the minor leagues.

Since 2020, Fujinami has made 27 major league starts and 34 relief appearances, along with 21 farm team appearances (19 of them starts). While he still had a double-digit walk rate in 2020 and ’21, his 7.6% clip in ’22 was the best of his NPB career, as he basically matched the league-average rate of 7.7%. His performance in the strikeout and walk department notably improved after a stretch in the bullpen and in the minors, with excellent peripheral numbers in the last two months of the season. He finished the year with a 3.38 ERA in 66.2 innings, but due to the lowered NPB offensive environment, that resulted in just a 102 ERA- (92 FIP-). While he wasn’t throwing more pitches in the strike zone than before, he significantly cut down on the number of waste pitches thrown, as evidenced by a career-high chase rate.

Update to The Board: NPB Prospects

© Yukihito Taguchi-USA TODAY Sports

Continuing our week of updating the International Players tab over on The Board, today we’ve added the need-to-know pros from Nippon Professional Baseball, the top league in baseball-obsessed Japan. If you missed yesterday’s post surrounding Korea Baseball Organization players, you’re going to want to check that out, as lots of what is outlined there is also relevant for this batch of reports.

NPB is made up of 12 total teams split between two leagues, the Central and Pacific Leagues, with roughly half the teams concentrated in the area of the country surrounding Tokyo Bay. Now just over 70 years old, NPB essentially has one level of affiliated minor leagues (also split in two, they’re called the Eastern and Western Leagues), but allows its franchises to vary in the number of affiliates they control, which creates vast disparities in the number of minor league prospects or developmental players teams employ. The Giants and Hawks are Branch Rickey-ing this space while other teams are not.

MLB personnel tend to consider Japan at least on par with Triple-A ball in the U.S., and some (including your author) think it fits somewhere in the yawning chasm between the level of play at Triple-A and in the majors. Evidence that the latter is true: the Quad-A hitters who leave the U.S. for opportunities in Japan don’t tend to dominate the leaderboards; the best NPB players are usually Japanese. There are historical exceptions to this, but no foreign-born player has cracked the single-season top 10 of NPB position player WAR since Hector Luna in 2014. Read the rest of this entry »
