Jung Hoo Lee Siblings: All About Lee Ga-hyun

Jung Hoo Lee is a South Korean professional baseball outfielder for the San Francisco Giants in Major League Baseball.

Born Lee Jung-hoo on August 20, 1998, in Nagoya, Japan—while his father was playing in Nippon Professional Baseball—he is widely known as the “Grandson of the Wind,” a nickname inherited from his legendary father, Lee Jong-beom, who was called the “Son of the Wind” for his blazing speed.

Lee has earned a reputation as a contact hitter with excellent bat-to-ball skills, strong defensive play in center field, and the ability to get on base consistently.

He signed a six-year, $113 million contract with the Giants prior to the 2024 season.

Siblings

Jung has one younger sister, Lee Ga-hyun.

In January 2023, she married Go Woo-suk, a prominent right-handed pitcher who transitioned from the KBO to MLB with the San Diego Padres.

Lee has shared lighthearted stories about his initial reaction to learning that his friend and rival was dating his sister, including a memorable phone call where he jokingly questioned the relationship.

Career

Lee grew up immersed in baseball in South Korea after his family returned from Japan.

He attended Whimoon High School in Seoul and debuted professionally with the Kiwoom Heroes (formerly Nexen Heroes) in the KBO League in 2017.

Over seven seasons in the KBO, he posted an impressive .340 batting average with 65 home runs and 515 RBI, winning the KBO MVP award in 2022 and earning multiple batting titles and Gold Gloves.

His consistent contact hitting, speed, and defensive range made him one of the league’s brightest stars.

In December 2023, Lee posted for MLB and signed with the San Francisco Giants.

His MLB debut came on March 28, 2024, against the San Diego Padres.

He hit his first major league home run just two days later on March 30 in Petco Park, with family members—including his father—in attendance.

However, his rookie season was cut short by a left shoulder injury sustained while crashing into the outfield wall in May, requiring labrum surgery and limiting him to 37 games (.262 average, 2 HR, 8 RBI).

Lee returned healthy in 2025 and delivered a strong full season, appearing in 150 games while slashing .266/.327/.407 with 8 home runs, 55 RBI, 10 stolen bases, 31 doubles, and a league-notable 12 triples (tying the Asian player single-season record previously held by his idol, Ichiro Suzuki).

He led the Giants in several offensive categories, including batting average and extra-base hits.

In 2026, Lee has continued to contribute as a key member of the Giants’ outfield, showcasing his signature contact-oriented approach and defensive versatility despite some early-season challenges.

Accolades

In the KBO, Hoo Lee claimed the league MVP in 2022, multiple batting titles, and several Gold Glove awards for his elite defense in the outfield.

He also earned playoff MVP honors in 2019, exactly 26 years after his father achieved the same feat, marking a historic father-son milestone.

In MLB, Lee earned recognition for his strong 2025 campaign, where his 12 triples ranked among the league leaders and underscored his speed and gap power.
