Shun Yamaguchi | Early Life

Yamaguchi was born on July 11, 1987, under Cancer’s sun sign to his parents Keiko Yamaguchi and Yamaguchi Hisashi.

Since there is no mention of his siblings, we believe he might be a single child born and raised in Oita, Japan.

Additionally, Yamaguchi hasn’t opened about his childhood, and we can expect it to be peaceful and memorable.

As a matter of fact, Yamaguchi’s father, Yamaguchi Hisashi (April 16, 1952 – October 19, 2010), was a sumo wrestler. To elaborate, he debuted in January 1971 and reached the top division in May 1978.

Throughout his career, his father reached maegashira 4, until he finally retired in November 1982. 

Amateur Career

Following his father’s footsteps, many expected Shun Yamaguchi to follow his father’s footsteps and get involved in the sumo wrestling arena.

However, right after his high school graduation, Yamaguchi started playing baseball and devoted his time.

What’s interesting is his sense of humor that explains why he chose baseball over sumo wrestling. 

“As I got older, I started thinking about showing my butt [in public], so I think that’s why.”
-Shun Yamaguchi

Initially, he starred in his high school team of Yanagigaura High School, where he had his pitching of 94 mph. 

With interest in baseball, he commenced his career through the 2005 high school draft. Back then, the Yokohama BayStars drafted Yamaguchi in the first round to feature in the Nippon Professional Baseball.

After a year of selection, Yamaguchi made his debut for the league in 2006. Back then, he devoted ten years to the Yokohama BayStars until eventually signing in with the Yomiuri Giants in 2017.

As a rookie in the team, Yamaguchi a 6.30 ERA by 2007 and then moved to the bullpen in 2008.

Afterward, he featured as the closer for the team until three years. He posted 18 saves and a 3.27 ERA during those tenures and even stood 6th in the Central League in saves.

Later, he was even named to the 2010 NPB All-Star Games. Before that, he stood 3rd in saves behind Hitoki Iwase and Chang-Yong Lim.

In the meantime, he bagged his second consecutive all-star and broke the record of Hiroaki Nakayama for the game finish. 

After series of gameplay and smooth games, he had to step down as a closer. Therefore, Jorge Sosa replaced him for the closer duty.

Thus, Yamaguchi was in the starting rotation and then advanced to being a regular starter. 

Within a few years, again in 2016, Yamaguchi had a good start, where he tied Tomoyuki Sugano for the complete games. The very next year, he signed with the Yomiuri Giants as a free agent.

After signing, his first year with the team was limited with just four games to play due to his shoulder problems.

Not only this, but he also had to serve in suspension after attacking security games while he was drunk. Moving on to next year, he completed every game of the season without any injury or scandal. 

Apparently, 2019 is marked as his best season as a starter, where he had maintained a 2.91 ERA. Infact, that year, he was the opener for the 2019 Japan Series, and therewith, he made the Best Nine for the first time.

Altogether, he ended the series after becoming the second in voting for the 2019 Central League Most Valuable Player Award.

Consequently, Yamaguchi ended the season after making three starts in the 2019 Premier 12. After the 2019 WBSC Premier12, Yamaguchi announced to enter the posting system to play in Major League Baseball (MLB).

Therewith, on December 3, 2019, Yamaguchi became the first player in Giants history to be posted in the MLB.

On December 28, 2019, Toronto Blue Jays signed Yamaguchi with a two-year contract worth $6.35 million.

Subsequently, now he features in the number one jersey for the team. With his entry came the press conference on January 15, 2020, closely followed by the fan meeting. 

However, Yamaguchi couldn’t start his gameplay right then due to the outbreak of the pandemic.

Thus, he returned to Japan on March 26 and only returned after the regular season’s announcement. 

Likewise, his MLB debut was not a good start that took on July 27, 2020. Advancing further, he claimed his foremost MLB victory on August 26.

To date, Yamaguchi has played 17 games in total for the team, and his statistics stand as a 2–4 record with 8.06 ERA and 26 strikeouts in 25.2 innings pitched.

“The Blue Jays are the only team that plays in Canada, not on the U.S. side; I think that makes it so much different than other teams. And Major League Baseball is the No. 1 in the world. So for me to play for Blue Jays and play the highest level baseball in the world, I think it means a lot.”
-Shun Yamaguchi 

Shun Yamaguchi | Playing Style and Achievements 

As one of the top pitchers in Japan, Yamaguchi mostly relies on three of his top pitches: the fastball, the splitter, and the slider.

As a known fact, he is a right-handed pitcher who has had 26 strikeouts. All the pitches and throws of Yamaguchi are at 90 mph (tops out at 95 mph).

“I’m not going to change my pitching style — I’m still a [ground-ball] pitcher.  I want to make sure that I get a swing from a ball instead of being a strike. Those are some of the adjustments that I want to keep making moving forward.”
-Shun Yamaguchi 

Although Yamaguchi has yet to earn a spot and mark his name in the MLB, he is an accomplished one in the NPB. Some of the achievements during his NPB’s tenure are highlighted below. 

  • 4× NPB All-Star (2010, 2011, 2016 & 2019)
  • Wins leader (2019)
  • Strikeout leader (2019)
  • Best Nine Award (2019)
