Kai-Wei Teng

Teng's 2026 K rate is elite: 62 K in 60.1 IP = 9.26 K/9. Last 3 starts: 4K (CLE, 6 IP), 9K (DET, 3.1 IP), 5K (@LAA, 4 IP) — two of three over 4.5. The outs market at 15.5 under (-170) signals market expects roughly 5 innings from Teng; at 9.26 K/9 over 5 IP that projects to 5.1 Ks, clearing the line. Last time facing this DET lineup (Jun 15): 9K in 3.1 IP confirms strikeout upside against this group.

Teng's 2026 season K/9 is 9.63 (58 K in 54.1 IP), but outing length is the core risk. Last 3 starts: 3.1 IP (9 K), 4.0 IP (5 K), 5.0 IP (1 K) — averaging 4.1 innings per start. That declining K trend (9→5→1) and consistent early hook means he projects 4–5 Ks at most in a typical outing. In his lone start vs CLE (Apr 21), he managed only 2 K in 2.2 IP. At 4 innings of work using his season rate, projection is ~4.3 Ks — well short of 5.5. Extended 6-day rest may improve command but won't fix his 4.31 BB/9 control profile or pattern of short starts. Under is the play.

Teng's 2026 K/9 is 8.65 (49 K in 51 IP), but his last 3 starts reveal dangerous variance: 5 K in 4 IP (exited with 5 ER vs LAA), 1 K in 5 IP (vs PIT), 7 K in 5 IP (vs MIL). That's 13 Ks across 3 starts — 4.33 per outing average, well under the 5.5 line. He's been cut at 4–5 innings consistently, capping his K ceiling regardless of rate. DET's offense is below average (.234 AVG, .705 OPS) and doesn't offer premium strikeout upside. The Jun 04 outing (1 K in 5 IP) isn't a fluke — it reflects Teng's inning-to-inning inconsistency as a converted swingman.
