Iwakuma to the A's

The Oakland Athletics have won the bidding for Japanese RHP Hisashi Iwakuma. Iwakuma isn't your average Japanese star pitcher coming from Japan. He went 13-6 with a 3.25 ERA, but just 121 K's in 24 starts and 169 IP. He gave up 169 hits, more than a hit per inning, although he did walk just 43. Contrast him to other big name Japanese starters Daisuke Matsuzaka, who struck out 200 in 186.1 IP his last year in Japan, and Hideo Nomo, who struck out 126 in 114 IP his last year in Japan and 276 in 243.1 IP in his last full year in Japan. Iwakuma's strikeout rate in his last year in Japan is not even comparable to Kei Igawa's stats in his last year in Japan. Igawa struck out 194 in 209 IP, an 8.4 K/9, compared to Iwakuma's 6.4 K/9. To go through a few other active Japanese pitchers, Hideki Okajima had a 10.5 K/9, Kenshin Kawakami had an 8.6 K/9, Takashi Saito had a 7.9 K/9, Hisanori Takahashi also had a 7.9 K/9, while Koji Uehara had a 7.3 K/9, and Hiroki Kuroda, 6.2 K/9. Let's look at those last 4 guys. Kawakami has been up and down as a starter in the big leagues, while Saito, Takahashi, and Uehara have enjoyed success in the big leagues as relievers, and Kuroda has been a successful starter. Among that group, the A's obviously hope that Iwakuma will be most like Kuroda.

The comparison between Iwakuma and Kuroda goes further. Iwakuma posted a 2.3 BB/9 in Japan in '10, similar to Hiroki Kuroda's 2.1 BB/9 in his last year in Japan. Kuroda's career BB/9 in the majors is also 2.1. Could Iwakuma also maintain his 2.3 BB/9? Interestingly, Kuroda's strikeout rate has gone up from 6.2 per 9 to 6.6 per 9 in America. Could the same thing also happen to Iwakuma?

In comparing Iwakuma to Kuroda, I'm realizing this: Iwakuma isn't going to be a big league superstar unless he really becomes a much better pitcher against big league hitters. He will be a nice 3rd starter, posting an ERA in the low to mid 3.00's (Kuroda's ERA in the big leagues has ranged from 3.39 to 3.76). He won't blow away hitters, but he'll get outs. Iwakuma's hype isn't anywhere near what Dice-K's hype was when he came to the US. But, considering Matsuzaka's struggles, Iwakuma certainly has as good of a chance as he does to be "the next great Japanese pitcher".
