2025 Fantasy Outlook
Mathews was a workhorse at Stanford, but he only averaged 91.6 mph with his fastball as a junior and was selected by the Cardinals in the fourth round of the 2023 draft. He showed up in 2024 sitting in the mid-90s (touching 98 mph) with above-average ride on that pitch and was arguably the top breakout pitching prospect of the year. The 6-foot-5 lefty logged a 2.76 ERA, 0.98 WHIP and a 202:49 K:BB in 143.1 innings across 26 starts, beginning the year at Single-A and finishing the year at Triple-A. In addition to his massively improved fastball, Mathews boasts a borderline plus-plus changeup and a comfortably above-average slider. He struggled in a small sample at Triple-A, with two five-walk starts bringing down his numbers at that level as he adjusted to the balls and strikes challenge system. Even so, he should be given every opportunity to win a spot in the big-league rotation this spring, and he will spend the bulk of his age-24 season in the majors, barring injury or a significant skills decline.

Activated from Triple-A IL
Mathews (shoulder) was activated from Triple-A Memphis' 7-day injured list Saturday.
ANALYSIS
After missing more than a month of action with left shoulder inflammation, Mathews tossed five scoreless innings with an 8:0 K:BB in two rehab outings before being activated. His first outing back in the Memphis rotation didn't go as well, as he yielded two runs with a 3:3 K:BB over 2.2 frames Saturday. The southpaw has permitted nine runs with a 10:18 K:BB in 13 innings covering four starts with Memphis this season, so he'll be looking to get back on track in June now that he has hopefully put his shoulder issue behind him.
