The Giants trimmed their surplus of young starting pitching on Thursday evening by trading right-hander Kai-Wei Teng to the Houston Astros in exchange for catching prospect Jancel Villarroel and international slot money, the team announced. By dealing Teng, San Francisco creates an open spot on the 40-man roster for outfielder Harrison Bader, who reportedly agreed to a two-year, $20.5 million deal on Monday. Teng, 27, is coming off an odd yet intriguing season with San Francisco. On one hand, Teng had a poor ERA (6.37) and unsavory walk rate (5.16 BB/9). The 21-year-old mainly caught (54 games) in ’25 but saw time in left field (19 games), right field (four games), second base (seven games) and first base (one game).
