Overview
- Major League Baseball confirmed that right‑hander Jyun‑Yue Tseng has been posted and will be available to sign during a negotiating window that begins Sunday and runs through Dec. 22.
- Tseng went 5‑3 with 25 saves in 48 games in the CPBL in 2026 and struck out 65 batters in 52.1 innings, building on a six‑season pro record that includes a 2021 Rookie of the Year award.
- Scouts note a mid‑90s to upper‑90s fastball with a slider and splitter and point to his scoreless appearances and a save for Chinese Taipei in this year’s World Baseball Classic as evidence of his high‑leverage experience.
- Under the MLB‑CPBL posting agreement clubs pay a graduated posting fee tied to contract value plus a 15% supplemental fee on bonuses and escalators and a 25% fee on signing bonuses for minor‑league pacts.
- The Dec. 1 expiry of MLB’s collective bargaining agreement creates a real risk the league could lock out players and shorten Tseng’s window, so teams weighing interest from sources such as the Cubs, Pirates and Dodgers face an urgent timing and cost calculation that could push the player toward NPB or a lower‑cost development path if talks stall.
