Figured out (1)

"2 outs! Keep it up Kenny!"

Yusuke called out from 2nd base, trying to cheer up the tall guy on the mound who seemed to be brooding. 

Ken flinched hearing the nickname that only his parents called him. His expression darkened as he sent a stiff smile towards his good friend Yusuke.

'Do you want to die?' 

His eyes seemed to convey his thoughts as the perpetrator quickly shut his mouth in fright.

Daichi who was now in the batters box couldn't help but laugh out loud hearing Ken called his nickname on the field. He wouldn't even let his own brother call him that, so he knew exactly how much Ken hated it being used by others.

If they weren't in a game right now, Daichi would have probably teased him some more. However, there were more interesting things to come now.
