Sean Manaea and “Dead Arm”
By all accounts, Sean Manaea is not feeling any pain in his arm and while players aren’t always entirely truthful with coaches or with media one has to, at this point, take him at his word. So you can understand the A’s continuing to trot Manaea out there even if his fastball velocity is down and even if he is struggling to get batters out.
After all, if you want a pitcher to build up arm strength and stamina for a full season’s workload, then you have to let him reach higher and higher innings markers.
