2026 Fantasy Outlook

After struggling in four relief appearances the previous season, the Giants non-tendered Teng before re-signing him to a minor league deal without a 40-man roster spot. He earned another opportunity by August 1 after posting a 3.67 ERA, 1.11 WHIP and 86 strikeouts over 54 innings for Triple-A Sacramento. Teng made eight appearances for San Francisco, including seven starts, but the results did not carry over. He struck out 39 batters in 29.2 innings, yet 17 walks inflated his ratios. Control has long been an issue for Teng, and that problem resurfaced at the major league level. He works with average velocity, sitting around 93 mph with his four-seam fastball and sinker, and complements them with a curveball, slider and changeup. The slider and changeup are his best offerings, and improved control could still allow Teng to settle into a relief role. Read Past Outlooks
