The Twins optioned Matthews to Triple-A St. Paul on Friday.
Matthews had been a candidate to make Minnesota's Opening Day rotation, but the 25-year-old will come up short. In 2025, the right-hander made 16 big-league starts, posting a 5.56 ERA and an 88:24 K:BB across 79.1 innings. Matthews' move to Triple-A likely means Mick Abel will have a spot in the Twins' rotation.
