Former big league outfielder and current member of Nippon Professional Baseball’s Yakult Swallows Nori Aoki is set to retire following the 2024 campaign, per an announcement from the Swallows yesterday (hat tip to The Yomiuri Shimbun). Aoki, 42, spent parts of six seasons in the majors in addition to a lengthy career in Japan.
Aoki’s career first began with the Swallows back in 2004 when he debuted at the age of 22. He made it into just ten games with Yakult that year, going 3-for-15 at the plate with a walk, a stolen base, and six strikeouts. That tiny sample size did nothing to suggest what Aoki would go on to do in his first full season with the club, however, as he slashed an excellent .344/.387/.417 in 144 games during the 2005 season, becoming just the second player in NPB history (after Ichiro Suzuki) to collect 200 hits in a single season.
He improved to even greater heights throughout his mid-20s, slashing 15-to-20 homer power to go along with fantastic contact and baserunning skills. As his plate discpline developed, he even began to walk more than he struck out, leading to a dominant stretch of seasons from 2007 to 2010 where he walked at a 10.6% clip against a minuscule 9.8% strikeout rate in addition to his aforementioned solid power and impressive base-stealing abilities, and even crossed the 200-hit barrier for a second time in 2010 to become the only NPB player in history to achieve the feat twice.
Given the excellence he had demonstrated throughout his time with the Swallows, it was hardly a surprise when he was quickly snapped up by the Brewers on a two-year deal after being posted for major league clubs prior to the 2012 season. In Milwaukee, Aoki was a slightly above average hitter with a solid .287/.355/.399 slash line. While he only hit a combined 18 home runs over his two seasons with the Brewers, he swiped 50 bags while hitting 57 doubles and 7 triples in that same period. That was a strong enough performance for Milwaukee brass to pick up Aoki’s club option for the 2014 season, but he did not last the offseason with the club and was swapped to the Royals in a deal that brought lefty Will Smith to the Brewers.
After departing the Brewers, Aoki wouldn’t stick around with an MLB club for more than a season at the time for the rest of his time in stateside ball. After acting as the regular right fielder in Kansas City for the club’s AL pennant-winning 2014 season, Aoki departed in free agency to sign with the Giants but was limited to just 93 games when he suffered a broken leg and a concussion in two separate hit-by-pitch incidents. Aoki then signed a one-year deal with the Mariners in 2016 but began to show some signs of decline, notably stealing only seven bases in sixteen attempts with the worst strikeout and walk numbers of his MLB career, though he did display his best power numbers since his rookie 2012 campaign with the Brewers.
Aoki’s final season in the big leagues came back in 2017 and saw him change uniforms several times. The veteran outfielder was claimed off waivers from the Mariners by the Astros during the 2016-17 offseason. Aoki struggled somewhat through 70 games with Houston, however, and ended up traded to the Blue Jays at the deadline that year alongside Teoscar Hernandez in a deal that brought Francisco Liriano to Houston. Aoki managed to catch fire down the stretch, however, and while his playing time was further split between the Blue Jays and Mets over the final two months of the season he slashed .281/.294/.594 for Toronto in August before slashing .284/.371/.373 in Queens that September.
Following the end of his MLB career, Aoki returned home to the Swallows and has played for the club in each of the past seven seasons. Now 42, the veteran is the league’s oldest active player and has collected more than 7,000 plate appearances with a .313/.392/.445 slash line in 1,713 NPB games. Between NPB and MLB play, Aoki has stepped up to the plate more than 10,000 times with 2,765 hits, 470 doubles, 51 triples, 179 homers and 279 stolen bases. We at MLBTR congratulate Aoki on a fine career and wish him all the best in his post-playing pursuits.
