SI: Hanshin Accepts Igawa Bid

November 28, 2006

Kei Igawa, Hanshin Tigers LHSPAccording to Jon Heyman of Sports Illustrated, Hanshin accepted a bid of $25 million for the posting rights to Kei Igawa. We should learn who the lucky winner was later today. Last month, I predicted a posting fee of $5-$10m for Igawa… yet another meal of ground glass to eat. Yum!

Here was my Kei Igawa 2007 MLB projection:

Matsuzaka Rumors

November 10, 2006

While we’re all waiting for Seibu to decide whether or not they accept the highest bid forMatsuzaka, let’s engage in a little rumor-mongering.

Wow. Olney, citing “officials monitoring the bidding”, says the Sox “may” have offered between $38 million and $45 million for his rights. That would be higher than every prediction in our contest except those of Steinbrenner and Dr. Evil (no commentary on the seriousness of their predictions).

It’s impossible to not enjoy all the hedging in these rumors-made-stories. In other news, Angelina Jolie “may” leave Brad Pitt to hang out with this author. It’s possible! The rumor the ST has says the Rangers may have offered “close to $30 million.”

Kei Igawa was either posted today or will be posted shortly. Bids should be due next week.

Japanese Projections – Part 2: Pitchers

November 8, 2006

Earlier, we talked about how hard it is to predict the future. As our old professor Larry Sabato used to say:

He who lives by the crystal ball ends up eating ground glass.

So, with that in mind, let’s fry up a delicious glass omelet!

Jim Albright’s system gives us the means to translate Japanese into American, so to speak: numbers from NPB become numbers from MLB. Of course, the translations overlook several factors. They do not account for park effects, for one. Another: they don’t adjust for age. And finally: they don’t account for league difficulty. These are problems I’ll try to tackle at some point in the future; but for now, we’ll overlook our beauty queen’s gapped teeth and barely noticeable moustaches, and get her ready for the swimwear competition.

The first set of translations are easy: we simply hold IP constant and multiply the other statistics by the translation factors. As mentioned yesterday, 100 hits in 100 IP become 107 hits in 100 IP. Et cetera. (Stats we don’t have translation factors for, like HBP and WP, were left unchanged). The largest adjustment turns out to be for home runs; despite the bigger parks in America, pitchers have trouble keeping the ball in the yard when they make the trip over here.

So, we’ve translated hits, home runs, strikeouts, and walks to MLB equivalents. What now? We used Bill James’ component ERA formula to calculate an ERC for each player. Then, based on the number of innings, we figure out how many earned runs that player must have allowed given the number of innings they pitched.

Aside: the ERC formula requires BFP (which we don’t have for all years) as one of its inputs. Using the Lahman database and Excel, I regressed BFP on IPouts, H, BB, K, HBP, and HR. I used the weights from this regression to estimate BFP. For a full season’s worth of hitters (800+ BFP) the calculated value is usually within 5 BFP and rarely further than 15 BFP from the correct value. Click here to see the regression results.

Then, using their historical ratio of R to ER, we take a stab at guessing how many unearned runs they might have allowed in addition. If we wanted, we could also try to guess how many wins and losses a player would have had based on their RA, an assumed team RA and run context. For now, we’ll just ignore them in our translated statistics.

After we have all our translations done, we should adjust everything for age and park. And maybe we will, later. But for now, a simple flat 3/2/1 projection without mean regression will have to suffice. What that means in English: we will assign each of the last three years a weight of either 3 (for the most recent year), 2, or 1. We will then calculate the weighted average for stats like BB, H, K, IP, etc. using that algorithm. ERC, ER, and R are re-calculated as described above. Finally, we will re-calculate starts and innings pitched based on the assumption that Japanese pitchers will throw fewer pitches per start (but start more frequently) in America, and pro-rate other stats accordingly.

Aside: Since the start of the 2000 season, 420 pitchers have started at least 25 games with one team during a season while making no relief appearances. I calculated the average number of batters those pitchers faced per start — it’s 26.7. From this number, we can assume either a number of starts or a number of batters faced and back into innings pitched (and hence other numbers) that way.

Kei Igawa

Here’s how Igawa did in Japan the past three years:

Kei Igawa Actual Statistics

Pretty good numbers (although lots of home runs). 228 K in 200 IP looks great. Watch what happens after the translation:

Kei Igawa Translated Statistics

Some good, some bad. Note that Igawa’s BB/K ratios are always pretty good, though he gave up too many baserunners and homers in ’04 and ’05. Hard to find anything wrong with the translated 2006 line, although we find it a tad too optimistic a translation. Keep in mind that GS has not been adjusted, and it’s unlikely that Igawa would have stayed in each start as long as these stats would lead you to believe. We will adjust for that in his projection.

Aside: You might wonder why Igawa’s Japanese ERA was nearly identical in 2004 and 2005 yet translated so differently. The first numbers use his actual Japanese ERA; the second estimate what his ERA would have been in America given his component stats. Thus, despite posting similar ERAs in Japan in 2004 and 2005, Igawa’s components indicate he pitched much better in 2004 than he did the following year.

Now, we project his stats using the model described above. We will assume he makes 30 starts and faces 26.7 batters per start. Also, we assume he plays for a team that scored 4.85 runs per game (splitting the difference between the AL and the NL, as this is projection applies to neither league in particular). Finally, we’ll assume he got a decision for every 9 IP and calculate his winning percentage using James’ pythagorean formula with an exponent of 1.82. That gives us this:

Kei Igawa 2007 Projection

The ERA is deceptive – he’s giving up a lot of unearned runs. Basically a league-average starter. This line is somewhat similar to Matt Clement or Jeremy Bonderman ca. 2005. If he can match this projection, he’s worth Jeff Suppan money.

Hiroki Kuroda

Kuroda apparently re-signed with the Carp already, but let’s take a look anyway. Japanese actual stats:

Hiroki Kuroda Stats

He doesn’t strike out a ton of hitters, but he keeps the ball in the park and has great control (his R/ER ratios are surprising – they’re very low for a groundball pitcher, as he reportedly is). Translated:

Hiroki Kuroda Translated Stats

Those hold up very well, mainly because he doesn’t walk anyone and keeps the ball down. Note the 2005 3.17 translated ERA matches the 3.17 actual ERA by a lucky quirk: his Japanese peripherals suggested he was unlucky to have an ERA as high as it was. Projected to 2007:

Hiroki Kuroda 2007 MLB Projection

A Cy Young candidate in the National League. Two important caveats: first, there’s no age adjustment, and he’s on the bad side of 30. This would cause him to take a hit. Second, it seems unlikely that a guy who relies on control could allow so many balls in play but so few over the fence. This projection is probably at least a run too low.

Kazumi Saitoh

Ahh, my favorite player in NPB. His numbers are fantastic; how will they hold up? Actual numbers:

Kazumi Saitoh Stats

Not a lot of innings in 2004 and 2005; was he hurt? Tons of runs in 2004 despite pretty good peripherals, too. Translations:

Kazumi Saitoh Translated Stats

Not a bad 2006, huh? The H/9 looks too low, though. He would have run away with the Cy Young if he put up those numbers in MLB. 2007 projection:

Kazumi Saitoh 2007 Projection

Sign me up! I’m not sure if he would be able to sustain the BABIP, though. I think this projection is a tad optimistic, but I buy it more than Kuroda’s. Note that I didn’t give Saitoh 30 starts, as that would have been a reach given the number of innings he’s thrown recently.

Daisuke Matsuzaka

What we’ve all been waiting for. Actual stats:

Daisuke Matsuzaka Actual Stats
Absolutely dominant. 138 hits in 186 innings is incredible. He did miss a few starts in 2004 to injury. Translated:

Daisuke Matsuzaka Translated Stats
It’s hard not to get excited. K/BB is still over 5. HR rates are low. Wow. And the projection:

Daisuke Matsuzaka 2007 Projection
Wonder why teams are bidding $25 million just to talk to this guy? Now you know. He probably won’t be this good — his projected BABIP is too high, for instance. But you never know…

Report: Igawa to be Posted

November 3, 2006

Interesting stuff. The Daily Yomiuri reports that the Hanshin Tigers will allow star LHP Kei Igawa to follow his dream and jump over to MLB by posting him next week. Igawa is scheduled to start next Tuesday in the NPB/MLB All Star series currently underway in Japan. I expect Hanshin expects to replace their star with free agent Hiroki Kuroda, who the article reports is filing for free agency despite a contract offer of 3 years, 1 billion yen from his current team.

As for Igawa, he’ll probably have plenty of suitors. Along with all the losers in the Matsuzaka sweepstakes, expect the Mariners, Dodgers, and Braves to be interested.

NPB Player News

November 2, 2006

I’m slammed today, so projections will have to wait. In the mean time…

The Mariners, considered by some to be the favorites for the Daisukster, decided not to bid on him when he is posted. This will come as a surprise to lots of folks – the M’s obviously have had a lot of success with previous imports Ichiro! and Kenji Johjima, so it only made sense that they’d try to go to the well again. What does this mean? A (slightly) lower winning bid, perhaps, and a lot of disappointed fans in Seattle.

So the impetus for this story is an article on Yahoo! Japan; I don’t read Japanese, so I’ll have to take the MLB Trade Rumors folks at their word. The Hanshin Tigers are making a pitch for Kuroda. However, if Kuroda signs with Hanshin, that probably makes Kei Igawa more likely to be posted. See below.

Igawa wants to come over and has for years; he’s a bit of a showman, apparently, and wants to show what he can do in MLB. If Hanshin wants Kuroda, the posting fee they earn from Igawa would pay for a bunch of free agents. Stay tuned.

Japanese Future MLBers: #5 – Kei Igawa

October 26, 2006

Of the free agents that might be posted by NPB clubs this offseason, Kei Igawa is far from the sexiest; however, he might be the best bargain.

Kei Igawa, Hanshin Tigers LHSP Igawa, drafted out of high school by the Hanshin Tigers in 1998, is a 6’1″ left-handed starting pitcher who weighs about 210 pounds. He broke into the Tigers’ rotation in 2001 and put up a very nice season, although his won/loss record did not reflect that as the Tigers were bad. He’s been in the rotation ever since, excepting a brief demotion to the minors in 2005. 2008 [This used to be 2007, but has since been corrected. -SGR] is the final year of his contract with Hanshin; after the season ends, he becomes a free agent, and can sign with any team (NPB or MLB) he chooses. Therefore, Hanshin is likely to post him this season and earn a fee while they still can, much like MLB teams that trade impending free agents at the trading deadline every July.

Among the pitches in Igawa’s arsenal are a tailing fastball that sits in the high 80s and can be dialed up to the low 90s, a slider/slurve in the high 70s, and a diving change-up in the low 80s. His breaking ball is probably his most effective pitch.

Igawa’s delivery, unlike that of other Japanese pitchers like Hideo Nomo or Daisuke Matsuzaka, does not include a long pause during his windup. In the past, such pitchers’ novelty effect seems to wear off after a few trips around the league; maybe Igawa will be immune from this effect. He has a high 3/4 arm angle that he keeps mostly consistent from pitch to pitch. See the following YouTube video for game footage from this year:

Igawa does not profile to be the potential ace that his countryman Matsuzaka appears to be, but he looks like a perfect #3 starter – someone capable of a league-average ERA and 200 innings with consistency. Look for him to command a posting fee in the neighborhood of $5-$10 million, and an annual salary between $6m – $8m for a multi-year contract.
