Teng carries a high walk rate (14 BB) with a 1.76 WHIP, raising run chances for opponents. He’s capable of short bursts of effectiveness, but control problems can unlock big innings for the other side in a tight game.

Teng carries a rough first year with an elevated ERA and WHIP, but he’s a risky, high-upside flyer against Arizona’s offense, offering discount-friendly exposure to a slate with strong cost-efficiency plays.

Teng’s Coors Field season debut featured an all-out, eight-strikeout performance, using a sweeper-heavy mix to attack Rockies hitters despite the altitude. He worked in and out with a fastball and curve, kept the Rockies off balance, and avoided free passes, leaving the Giants with a sizable lead before the late innings.

Teng logged 5 1/3 innings of two-run ball with eight strikeouts, his longest MLB outing, in a spot start for the injured Whisenhunt, underscoring his emergence as a viable rotation depth piece.

Kai-Wei Teng, Giants rookie starter, carries a limited MLB track record but sits in a pivotal September spot. He relies on a sweeping slider paired with a fastball in the low-to-mid 90s, and his first Rockies matchup will test his ability to induce weak contact and miss bats early in a tight wildcard race.
