70's game - fielding

Skill level standard. Fred Lynn is a "1(e6)". Two games in a row he allowed a "Double & Error - CF
1-H b-H". How does this happen?
Thank you in advance.

It was a normal double (not off x-chart), then probably a throwing error when someone tried to score---super advanced maximum rules on cutoff throws.
