Huh? I think it's the opposite. Goins has a beautiful swing, but he can't hit anything with it and can't aim his bat very well. He might be better to try slap hitting.
Yes thats situational. Players dont perform better or worse in different clutch situations. Clutch doesnt exist. Its just up to the manager to use the right guys at the right time.
The bullpen has been fine. 13th in SIERA, 15th in WAR, 15th in ERA-, 10th in SwStr%. There isnt a meteic where they have been bad except for situational which is just random.
