Riley O'Brien, the half-Korean pitcher for the St. Louis Cardinals, plans to pitch for Korea at the World Baseball Classic (WBC) in March, a report out of St. Louis said Saturday (local time). Derrick Goold of the St. Louis Post-Dispatch said O'Brien, 30, accepted the invitation from the Korean national team and is working on plans to travel to Japan, where Korea will play all four opening-round games. The tournament goes from March 5 to 17. Thanks to loose eligibility rules for the WBC, players can represent the country of birth of one of their parents, even if those players themselves weren't born in that country. For the 2023 WBC, Korea had Gold Glove-winning infielder Tommy Edman, who was born in the U.S. to a Korean mother. O'Brien was born to a Korean mother and has the Korean name Chun-young. Korea manager Ryu Ji-hyun said earlier this month he was hopeful about three to four U.S. players of Korean descent would join his team for the WBC. While Edman has already been ruled out due to an offseason ankle surgery, Korea, in addition to O'Brien, may also get the services of Detroit Tig
