Hisashi Iwakuma (岩隈 久志 Iwakuma Hisashi?, born April 12, 1981 in Higashiyamato, Tokyo, Japan) is a starting pitcher for the Tohoku Rakuten Golden Eagles.

The Eagles' current staff ace, Iwakuma won the Eiji Sawamura Award in 2008 and played in the 2004 Athens Olympics as well as the 2009 World Baseball Classic for the Japanese national team.


Early life and high school career

Iwakuma was born in Higashiyamato, Tokyo, and began playing baseball in the first grade before attending Horikoshi High School in Nakano.[1] While he never made it to a national tournament during his high school career, he led his team to the semi-finals of the West Tokyo Tournament as a senior in the summer of 1999. The Osaka Kintetsu Buffaloes picked him in the fifth round of the 1999 NPB amateur draft.

Professional career


Early years: 2000 to 2003

Iwakuma spent the entirety of his rookie season (2000) with the Buffaloes' nigun (Japanese for "minor league" or "farm team") team, clocking 149 km/h (93 mph) with his fastball at one point but making only two appearances all year in the Western League.

Iwakuma made his debut at the ichigun ("major league") level the following year, appearing in relief in a game against the Nippon Ham Fighters on May 29 2001 and earning the first career win of his professional career despite giving up a run over 1 2/3 innings. He made his first start on June 10 against the Fighters and threw his first career complete game (a two-hit shutout) against the Seibu Lions on September 18, finishing the year with a 4-2 record and playing an important role in the Buffaloes' league title that year.

Iwakuma secured a spot in the team's starting rotation by 2002, the following season, going 8-7 with a much-improved 3.69 ERA in 141 1/3 innings. He enjoyed a breakout year in 2003, going 15-10 with a 3.45 ERA and 149 strikeouts and leading the league with 11 complete games.


Iwakuma made further strides in 2004, beginning the season 12-0 and establishing a franchise record for most consecutive wins to start the season. He received the most fan votes among Pacific League starting pitchers for the NPB All-Star Game that year, starting Game 1 at Nagoya Dome on July 10, and pitched in the 2004 Athens Olympics as a member of the Japanese national team in August. He finished with a 15-2 record for the year, leading the league in both wins and winning percentage (.882)[2] for the first time in his career. He also pitched in Game 5 of the MLB All-Star Series held in November, holding the MLB All-Stars to one run over seven innings to earn the win.

Following the 2004 season, Iwakuma's Buffaloes and the Orix BlueWave, another Pacific League team based in the Kansai region, opted to merge to alleviate some of their financial difficulties, later leading to the addition of a new team named the Tohoku Rakuten Golden Eagles that would fill the void created by the merger. Iwakuma was initially named a member of the newly-formed Orix Buffaloes in a dispersal draft held that November, but refused to comply and join the Buffaloes and became involved in a contractual dispute.[3][4] Although the Buffaloes attempted to persuade him to play for their team, they eventually agreed to trade him to the Eagles in exchange for cash.[5]


Iwakuma was named the Eagles' starter for the 2005 season opener, holding the Chiba Lotte Marines to one run while going the distance on March 26 and earning the expansion team's first-ever win.[6] However, while he did not miss a single start during the regular season, he was bothered by tenderness in his shoulder throughout the year, finishing with just nine wins (amidst 15 losses) and an ERA of 4.99 (worst among all qualifying pitchers).[7]


Iwakuma's injury woes continued into the 2006 season. His struggles to adapt to the league's new rules on pitching motions during Spring Training, combined with lingering concerns about his shoulder condition, caused him to miss the season opener and spend the entire first half of the season with the nigun team undergoing a rehab stint. He made his first appearance of the season against the Fighters on August 29, but did not record a win until September 12 in a game against the Marines, finishing the season with a 1-2 record and 3.72 ERA in just six starts.


In 2007, Iwakuma was named the starter for the season opener for the first time in two years, taking the mound on March 24 against the Lions. While he was slated to start the Eagles' first home game of the season on March 31 against the Buffaloes as well, he reported stiffness in his back just hours before the game, causing him to be scratched from the lineup and sent down to the minors for rehab the next day. He returned at the end of April only to be demoted again just weeks later with a left oblique strain. Iwakuma finally returned after the All-Star break, notching his second win of the season on July 31 and finishing the season with a 5-5 record in 16 games and an ERA of 3.40. He underwent arthroscopic surgery on his right elbow in October.[8]


Chosen to start the season opener for the second straight year (and fourth time overall), Iwakuma pitched against the Fukuoka SoftBank Hawks on March 20 2008, but fell short of the win despite limiting the Hawks to just one run over seven innings (then-closer Domingo Guzmán gave up a walk-off home run to outfielder Hiroshi Shibahara, handing Iwakuma a no-decision in a 4-3 loss). However, he recorded his first complete game shutout with the Eagles in his next start on March 27 against the Buffaloes and recorded his 10th win of the season in another complete game shutout against the Yomiuri Giants in an interleague game on June 15, marking the first time he had reached double-digit wins since 2003, when he was still with the Buffaloes. Though he expressed disappointment that he was not chosen to play in the 2008 Beijing Olympics as a member of the national team (even though he ranked among the league leaders in several categories at the time), he notched his 16th win of the season, a new career high, on August 16 against the Marines, passing 1000 career innings pitched in that same game.

On September 22, in a game against the Saitama Seibu Lions, Iwakuma threw seven innings of one-run ball to become the first 20-game winner in the Pacific League since Hawks right-hander Kazumi Saito achieved the feat in 2003.[9] He picked up one more win on October 5 against the Hawks, becoming the first 21-game winner in 23 years (former Hankyu Braves right-hander Yoshinori Satoh won 21 games in 1985) and passing young rival and fellow ace Yu Darvish of the Fighters to lead the league in ERA (1.87) in his final start of the season.

Iwakuma finished his dominant 2008 campaign with a 21-4 record, leading the league in wins, ERA, and winning percentage (.840).[10] He gave up just three home runs in 201 2/3 innings all year, of which just one was to a Pacific League hitter (the other two were given up in interleague games), and won nearly one-third of the Eagles' 65 wins in the regular season himself. He was presented the Sawamura, Most Valuable Player and Best Nine awards at the end of the season, a rare accomplishment for a player on a fifth-place team.[11]


Iwakuma started the season opener for the Eagles for the third straight year in 2009, requiring just 59 pitches to throw six innings of one-run ball en route to the win on April 3 in a much-hyped match-up with World Baseball Classic teammate and 22-year-old Fighters right-hander Yu Darvish (who threw 121 pitches in a complete game loss, all three runs given up in the first inning).[12] He recorded his first complete game of the year on May 16 against the Hawks.[13]

International career

2004 Athens Olympics

Iwakuma made his first appearance on the international stage when he was named to the Japanese national team that would play in the 2004 Athens Olympics. Coming off a torrid 12-0 start to the regular season, Iwakuma took the mound in the second game of the preliminary round against the Netherlands on August 16. However, he allowed seven baserunners (three hits, three walks and a hit-batter) and gave up three runs (two earned) against a team that was viewed as the heavy underdog, leading head coach (and acting manager) Kiyoshi Nakahata to pull him from the game after just 1 2/3 innings.[14] Though Japan went on to win the game 8-3 behind a strong relief effort (five shutout innings) by current Los Angeles Dodgers right-hander Hiroki Kuroda, Iwakuma lost the trust of the coaching staff and did not pitch in the tournament again.

2009 World Baseball Classic

Chosen to play in the 2009 World Baseball Classic as a member of the national team[15], Iwakuma made his first appearance of the tournament in the final game of the first round against South Korea on March 9, holding them just one run over 5 1/3 innings but receiving no run support and being charged with the loss. He pitched six shutout innings in his second start against Cuba in the second round on March 18, earning his first win of the tournament.[16] His stellar effort convinced manager Tatsunori Hara to choose him over Darvish, who had been unofficially tabbed as the staff ace prior to the tournament, as the starter for Japan in the championship game against South Korea. Iwakuma did not disappoint, limiting the team to just two runs over 7 2/3 innings.[17] While Darvish gave up the tying run in the ninth after coming on in relief, Iwakuma played an instrumental role in Japan's eventual win and second consecutive title.[18] Boston Red Sox right-hander Daisuke Matsuzaka earned MVP honors for the tournament, largely on merit of his perfect 3-0 record, but Iwakuma finished the tournament with the lowest ERA (1.35) of any pitcher that threw 15 or more innings and was one of three pitchers named to the All-Tournament team.[19]

Pitching style


Iwakuma is a lanky 190 cm (6 ft 2 in), 77 kg (170 lb) right-hander with a high three-quarters delivery. He was well-known for his unique pitching motion during his years with the Buffaloes, letting his throwing arm hang at his side while he raised his left leg, lowered it halfway once, then raised it again before driving towards the plate. He was forced to overhaul his mechanics and implement a more orthodox delivery when the NPB changed its rules on pitching motions in the 2005 off-season, taking a stricter stance on so-called two-stage motions (those with pauses or breaks at any point in the delivery).[20] Iwakuma also raised his arm slot slightly in 2008 to induce more movement in his offspeed pitches.


Though Iwakuma's fastball clocked speeds as high as 153 km/h (95 mph) earlier in his career, after he hurts his shoulder it usually sits at 140 to 146 km/h (87 to 91 mph) today. He complements it with an exceptional splitter, slider, shuuto and curveball[21], often using the splitter as his out pitch. He records a moderate number of strikeouts each season but is inherently a groundball pitcher, adept at jamming opposing hitters with his wide assortment of offspeed pitches and excellent command[22][23] (2.08 career walks per nine innings rate as of May 16, 2009). Iwakuma has also remarked that his command has improved since missing much of the 2006 and 2007 seasons due to injury as he was forced to overhaul his mechanics and rethink his approach against opposing batters.
