Stop scrolling and look at the numbers. A lefty named Brandon Clarke is throwing 103.1 miles per hour in the Arizona Fall League. That isn’t just fast; that is historic speed. Baseball America’s Geoff Pontes put it bluntly when he compared Clarke to Jacob Misiorowski. Clarke matches the electric impact of Jacob Misiorowski for a single at-bat or inning, he stated, with few others comparable. That quote alone should make any Redbird fan sit up and pay attention.
This isn’t the old Cardinals way. We used to hoard soft-tossing pitchers who just tried to get ground balls. President of Baseball Operations Chaim Bloom is changing that game plan. The team now wants guys with massive upside, even if they come with a high risk of failing. Clarke fits that new mold perfectly. He sits at No. 9 on the MLB Pipeline list for the Cardinals farm system. He has already logged 29.2 innings across four minor league levels this season with a 3.34 ERA and 44 strikeouts.
The Misiorowski Comparison Holds Water
People love to compare prospects to stars, but this one feels different. At this moment, Misiorowski stands as the most dynamic pitcher across baseball. He does not just throw hard; he gets elite extension and spin rates too. If a scientist built a pitcher in a lab, it would look like Misiorowski. Clarke has that same electric feel. He is the hardest thrower in the entire Arizona Fall League for 2026. The velocity is real, and the potential ceiling is higher than almost anyone else in the organization.
Control Issues Mean We Wait
Do not go crazy yet. There is a reason to be guarded with all this hype. Clarke walks 5.2 batters per nine innings. That number is a career best for him, but it is still way too high. Misiorowski had the same problem before the Brewers fixed him. Scouts thought Misiorowski was a wild card because he only had a fastball and slider with spotty control. Milwaukee worked its magic by adding a wipeout curveball and cleaning up his command. They pushed his control to above average in the majors.
Clarke needs that same development help. He has the arm strength to dominate, but he cannot walk half the hitters he faces.
