It's a good chance for sawamura to show his reliability and how sturdy he is here. Momentum would definitely be theirs if he succeeds on striking him out.
But a larger chance for zono to get more mistakes since he'd be more conscious of it. More if sawamura fails. Brief reminder that he's injured too. Can't remember someone on their bench that's for first base.
DAMN, I KNEW IT!! THERE WILL BE ONE OR TWO MISTAKES BOUND TO HAPPEN!!
...but that's also normal, even in the real professional sport. Mistake sometime happen.
The real problem is how will Seidou get it over.
I mean, dude, if this batter hit a homerun, the flow will favor Sankou. And both Sawamura and Zono will filled with guilt. I wish Sawamura manage to get an out from this homerun monster.
