Wasn't the batting problem bigger than Sohn Hyung-jun's pitching yesterday??

A shutout loss for the professional team is a bit much..
The argument that we would have lost even if Kwak Been pitched because the offense couldn't score implies that if he had given up even 1 run, we would've lost.
There seems to be no need to scrutinize Sohn Hyung-jun's start.
The biggest issue seems to be the helpless batting.
