From Chelsea Janes:
Today Bryce Harper's Instagram story included a picture of scale reading 230 lbs. If he's the one standing on it, he has bulked up bigtime.

Bryce Harper is still maturing physically. It’s possible that his problem last year was he was no longer strong enough. What worked at 22 might not work at 23. Bigger and stronger is usually better.
