Junis would have been out of the inning except for a mental error by his first baseman. MLB doesn't score mental errors as errors so Junis gives up 5 earned runs instead of 2.
My son and Junis are close in age so I coached against Junis from 4th grade until High School. Then they competed against each other in the same conference in High School. Junis has a good slider and he can pitch well.
