The San Diego Padres officially announced a four-year contract with KBO star Song Sung-mun on December 23, following reports of an agreement. Manager Craig Stammen said playing the infielder in the outfield is 'definitely a possibility' to maximize his bat, while his 2026 World Baseball Classic participation remains undecided.
Building on earlier reports of Song's agreement with the Padres pending a physical, the team confirmed the signing of the 29-year-old Kiwoom Heroes third baseman on December 23, 2025. Song, who broke out with elite seasons in 2024 (.340/.409/.518, 19 HR, 104 RBI, 21 SB) and 2025 (.315/.387/.530, 26 HR, 90 RBI, 25 SB, Golden Glove), joins as a versatile option amid Manny Machado's hold at third.
In a December 24 Zoom press conference, manager Craig Stammen discussed Song's potential outfield role: 'He's going to feel more comfortable in the infield. But it's something we'll work on in spring training... It creates more versatility. He's a very good athlete.' Stammen envisions Song at third, second, first, or outfield, providing depth like Dodgers' utility players Kike Hernandez and Tommy Edman. 'World Series-winning teams have movable parts,' he said, noting Song can spell Machado or enable DH days.
General Manager A.J. Preller addressed Song's WBC status for the March 2026 tournament: 'We're always supportive... But he's coming to the States for the first time and anxious to make an impression.' Song, back in Korea, said, 'I have to discuss it more with the team.' A decision is expected before South Korea's WBC camp in Saipan (January 9-21).
Preller highlighted Song's plate discipline and positivity, akin to Padres' Kim Ha-seong. This marks the sixth Kiwoom Hero to MLB.
