That year, he led MLB in earned run average (ERA) and had a 1.26 ERA after 14 starts, the lowest by a Dodgers pitcher since the statistic became official in 1912.
After pitching four seasons for the Blue Jays, Ryu returned to Korea in 2024.
Early life and education
Ryu was born in Incheon, South Korea on March 25, 1987, and attended Incheon's Dongsan High School. He is working towards a master's degree in community physical education in Daejeon University. When Ryu was 10, his father bought him a lefthander's glove that goes on the right hand, so Ryu learned to pitch with his left hand.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Hyun-jin Ryu”, the useful work is to connect “south Korean professional baseball player (born 1987)” to the records capable of establishing context and consequence.
Biographical claims are most persuasive when dates, appointments and relationships can be traced to records created close to the events described. The source revision retrieved here is dated Jul 22, 2026. The linked authority identifier is Q50604. VIAF identifies the subject as 28149617032303752340. 1 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1987, 2013, 2018 and 2019.
Later biographies can compress uncertainty and repeat inherited reputations, so apparently settled claims may still require comparison. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
