The Houston Astros have acquired right-handed pitcher Kai-Wei Teng from the San Francisco Giants in exchange for a minor league player, according to Robert Murray, an MLB Insider for FanSided. Teng, 27, spent parts of the 2024 and 2025 seasons with the Giants at the major league level. Across those two seasons, he appeared in 12 games, including seven starts, compiling a 2–4 record with a 7.30 ERA over 40.2 innings. Teng made eight appearances in 2025, seven of them starts, and logged 29.2 innings. While his run prevention remained a challenge in 2025, Teng showed measurable improvement compared to his rookie season.
