Rest-of-Season Projections
2026 Fantasy Outlook
Kolek narrowly missed out on a rotation spot with the Padres last spring, beginning 2025 back at the Triple-A level. He got the call in early May for his first career big-league start, and Kolek proceeded to pitch 14.1 consecutive scoreless innings upon arrival, including nine in a historic shutout in Colorado. Not only was the 21-0 margin of victory one of the largest in a shutout in league history, Kolek became just second Padres pitcher to record a shutout in the 30-year history of Coors Field. The right-hander then posted a 5.10 ERA in his subsequent 12 starts before being shipped to Kansas City at the trade deadline. Kolek bookended his season with another strong stretch, posting a 1.91 ERA, 0.76 WHIP and 21:5 K:BB over 33 innings with the Royals. Even with that, Kolek, a groundballer with minimal swing-and-miss in his profile, won't be assured a starting role to begin 2026. Read Past Outlooks
Signed a one-year contract with the Royals in February of 2026.
Scoreless effort in rehab outing
Kolek (oblique) allowed no runs on three hits and a walk over four innings during a rehab start with Triple-A Omaha on Tuesday. He struck out two.
Analysis
Kolek made the first start of his rehab assignment as he works his way back from a Grade 1 left oblique strain suffered in spring training. The right-hander threw 54 pitches (36 strikes) and maintained a fastball velocity of 94.3 mph, in line with his previous levels. The 28-year-old should continue to build up his workload for another couple rehab outings before being activated from the injured list, though he may be ticketed to remain at Triple-A upon activation with no clear opening in the big-league rotation.
