When starting pitcher Hisashi Iwakuma declined the Seattle Mariners’ qualifying offer of one-year for $15.8 million, it became clear that the team would be forced to compete with other major league clubs to bring the starting pitcher back to Seattle. The fact that the right-hander declined the offer comes to no surprise to most. It’s been widely reported that Iwakuma is looking for a multi-year deal.

Mariners GM Jerry Dipoto has made it clear that retaining Iwakuma is an offseason priority for his club and reportedly, the veteran hurler wants to stay in Seattle. Keeping “Kuma” in the Emerald City should be a lock, right? Maybe.

Much to the chagrin of some fans, Dipoto may be reluctant to offer Iwakuma the three-year deal that he’s reportedly seeking. Evidently, Seattle has offered a two-year contract with a vesting option for a third season.

Another hurdle in keeping Iwakuma is the fact that he may have several suitors other than the Mariners. Anthony Fenech of the Detroit Free Press tweeted that the Detroit Tigers were interested in the 34-year-old. Some teams may view Kuma as a less expensive alternative to top-tier free agents like Zack Greinke, David Price, or Johnny Cueto. If a market builds for Iwakuma, the Mariners could refrain from overpaying or over-obligating for the all-star starter.

The advantage that Seattle has on their side is the qualifying offer. If Iwakuma signs with another team, Seattle would receive a compensatory pick between the first and second rounds of the 2016 amateur draft. Any team that signs Iwakuma would have to their surrender first-round pick for the 2016 draft unless the team holds one of the first 10 picks. Those teams would lose their second-round pick instead.

Unfortunately for the Mariners and their fans, the Tigers own the number-nine overall pick. So, they’re legitimate competition for Iwakuma. Here is the entire first round draft order, plus the compensatory picks for next year’s draft.

Losing Iwakuma would be a blow to the Mariners offseason plans, but it’s important to keep his value in perspective. Let’s look at his major league numbers.

The 2013 season was the veteran right-hander’s first season as a full-time starter and it was by far his best season with the Mariners. Iwakuma started in 33 games and pitched a career-high 219 innings on his way to finishing third in Cy Young award voting.

Unfortunately, the 2014 season didn’t get off to a good start when he reported to Spring Training with a strained tendon in his right middle finger. After missing the first month of the season, he pitched like his 2013 self until September when he struggled during his last five starts when the team was trying to make the postseason.

Perhaps, the lack of Cactus League prep affected Iwakuma during the home stretch of the season or perhaps the veteran merely had a “rough patch” as Prospect Insider’s Tyler Carmont described it at the time.

This past season, Iwakuma started poorly with three sub-par starts before going on the disabled list with a right lat strain after his April 20 start. However, he bounced back nicely after returning in in July by pitching 100 innings during the second half of the season and throwing a no-hitter against the Baltimore Orioles on August 12.

All-in-all, Iwakuma has been a valuable pitcher during his stay in Seattle and he’s demonstrated the ability to be a number-two starter. However, he’ll be 35-years-old next season and is coming off two injury-shortened seasons. A team that intends to contend can’t rely on him to be their number-two starter entering 2016. A more realistic projection for Iwakuma going forward would be as a number-four starter.

Sure, it’s possible that Iwakuma will have a great season next year. But, is it reasonable for a team to commit three years to an aging pitcher who’s only pitched over 200 innings once during his major league career and only twice in 11 seasons in Japan?

Naturally, fans would like to see one of their favorites to return, but that’s not how winners are built. If there were a younger player available to sign, shouldn’t the Mariners explore that option?

If the team is going to be forced to obligate three years to a pitcher, wouldn’t it make sense to obligate those years and dollars to a free agent like Mike Leake rather than Iwakuma? Here are the 27-year-old’s numbers since Iwakuma arrived in Seattle in 2012.

2012 24 CIN 8 9 .471 4.58 30 30 2 0 179.0 4.42 1.352 10.1 1.3 2.1 5.8

The right-hander isn’t in the class of elite pitchers like Price or Greinke, but he’d be a nice fit as a replacement for Iwakuma. It’s true that Leake’s numbers aren’t at the same level of Iwakuma’s. However, his stuff should play well at Safeco Field and – thanks to his age – there’s a better chance that he’d be worth his asking price than Iwakuma, even if that means a five-year commitment.

Leake isn’t the only player who could help the Mariners fill out their rotation instead of committing three years to Iwakuma. Former Mariner Doug Fister – also a free agent – would also make more sense. Like Kuma, Fister has experienced availability issues in recent years and would likely cost a team less in dollars and years.

Bear in mind that signing Iwakuma to a third year would mean that the Mariners would paying a 38-year-old starting pitcher $13-15 million in 2018 when Nelson Cruz will be approaching the same age and earning similar money, plus a 35-year-old Robinson Cano will be banking $24 million.

Does paying approximately $52 million to three players – who are over the age of 35 – sound like a business model for sustainable success?

Retaining Hisashi Iwakuma for two years is an acceptable risk. Otherwise, there are other options – via free agency and trade – who would be more cost efficient than Iwakuma and just as effective or even better in 2016 and beyond.



  1. I can assure you free agent pitchers absolutely consider the home ballpark. No question, without exception, 100% of the time. Ballpark, city, team’s makeup, chances to win, lineup (chance to get WINS on his stat sheet), bullpen (holding leads he handed to them), the manager and how the staff has used/says they will use him and other pitchers, the weather in the city… all HUGE factors. No one deciding factor, but it all matters, just like the FACT that bats don’t flock to Safeco. They have to pay them aggressively to get them to come. Pitcher see Safeco as a safe place to pitch, where the smallest of mistakes bites them less than most parks. Where their efforts will be reflected in the numbers — yes, including WINS.

    Ballpark matters, A lot.

  2. As a side note, I really like the Leonys Martin addition. Nice work Jerry!!!

  3. I agree with Luke: the M’s need to address this situation rationally.

    The draft pick has to factor into the decision. We could have a conversation about whether or not the M’s should sign Iwakuma or someone like Scott Kazmir. They are very comparable talents, all else equal (most are predicting similar salaries). But all else isn’t equal: letting Iwakuma go would net us a pick in back of the first round (probably around the 25-30th overall).

    Or, the M’s could spend a few mil/year more, and go after someone like Johnny Cueto. Or maybe Kenta Maeda (who is a younger pitcher somewhat similar to Iwakuma). Or spread the wealth a bit, and sign Matt Latos AND Doug Fister. JA Happ is a legit option too. This is a very deep crop of free agent pitchers, even if we have to avoid guys attached to QO compensation.

    Since the M’s filled needs relatively cheaply with Martin and Karns. They should have some cash to spend now, especially if they can add a relatively cheap catcher (Iannetta!). We are all expecting Iwakuma to resign, and I think a lot of people expected it to be relatively cheap and simple like last time. I’d still bet they sort something out. But its not like there aren’t alternative out there. If Iwakuma is looking for something like 3-4 year at ~$15 mil AAV, there are LOTS of alternatives.

  4. I don’t know if Pitchers consider Safeco an advantage when considering the Mariners as a fre agent destination but Safeco with Leonys Martin patrolling CF can’t hurt the teams perception!

  5. Usually, money does talk the loudest. So far, that hasn’t been the case with Kuma. I’m not saying it won’t be this time either, but I’d be ok with giving Hisashi a fair market value at 3 years. Our window is Now, not 2 or 3 years from now. I agree with most of the posters in here that you shouldn’t over pay Kuma to be here, but as history has shown us, Kuna has been more than understanding when it comes to signing a fair market contract to be in Seattle, and I for one firmly believe that’s what will end up happening this time around too. 3-years/$45 million is high, but I’d pay it if it meant keeping Iwakuma here. Especially considering that he’s taken 2 MAJOR hometown discounts in the past. Not all will agree with me but I really don’t care. We’ll see what happens. At the end of the day though, my bet is that he’s the #2 come 2016!

  6. Paul, sometimes I don’t get where you are coming from. Dipoto won’t be forced to sign Iwakuma, he’s already stated that it’s a priority. If the ownership group decides they’re willing to pay what Iwakuma is asking, that’s a financial decision, like paying any other free agent.

    Exactly where did the “tons” of quality free agents thing come from. If there were tons of them available, none of them would be able to demand top dollar. And Safeco is not an advantage to an established pitcher. When they are established, they want to be paid, regardless of where they pitch. Safeco has a slight advantage for a pitcher who’s trying to re-establish their value, but in the day and age of advanced statistical analysis, it’s not worth a whole lot. Home-away splits tell a more complete story.

    There are few discounts in baseball. Unless you want more of the Jack philosophy, playing for discounts is a loser’s hand.

    I hope they sign Iwakuma, and think they will. But ultimately, it comes down to what the Mariners are willing to spend, and what Iwakuma wants. He likes playing in Seattle, but money always seems to talk the loudest.

  7. I would prefer that they resign Kuma, even if it takes a three year deal to get it done. They have the payroll space to accommodate him at a $15MM AAV. I don’t think some people appreciate the quality of his performance on the mound. He is still the team’s #2 starter until Walker or Paxton or a free agent signing show they are better. If they have to sign a replacement then Scott Kazmir would my choice, even at the 4/$52MM he’s projected to cost. Kuma has provided enough excess value in his 4 years with the team to cover the cost a 3/$45 deal even if he never threw another pitch for them.

  8. I am interested in seeing how this plays out. Will ownership force Dipoto’s hand and overpay to keep the Japanese player here? Kuma is injury prone and OLD! If it is going to take 3 or 4 years, at 15+ million a year, then I am not interested in signing him. Let someone else overpay for him! There are a ton of quality free agent pitchers out there. How many clubs are willing to pay top dollar for the starting pitchers out there? Won’t someone get left out of the bidding wars? I think if we are patient, we can get discount. Because Safeco is such an awesome pitchers park, we might get a pitcher that doesn’t find the deal they had hoped for accept less to come here. I could even see someone take a one year deal with us, put up good numbers, and then enter the market next year.

  9. Sentimentally, I would love to keep Kuma. I would prefer the 2 years with a club or vesting option as Luke suggests. If the bidding gets crazy, I wouldn’t mind Leake or Fister but Tyson Ross was officially labeled “available” in news stories today. I’d LOVE to get that guy. Would be spendy, though (in players, not cash….would be a trade).
