He is nearly completely ambidextrous; Kaminsky writes, throws a football, and shoots a basketball right-handed, but throws a baseball left-handed.[3][6] In Little League, he sometimes threw left-handed and sometimes threw right-handed.[3] He learned how to switch-hit when he was around 10 years old.[7]
In his senior year in 2013 Kaminsky was 10-0 with a 0.10 ERA, averaged two strikeouts per inning, gave up 14 walks as he struck out 126 in 64 innings, pitched three no-hitters and three one-hitters, while batting .506 with 3 home runs and 19 RBIs.[2][14][13][15] He was also a Baseball America Preseason First Team All-American and a Rawlings-Perfect Game First Team All-American.[2] Seattle Mariners scout Frank Rendini said: "He has a major-league curveball right now."[3][16]
While in high school, Kaminsky raised over $30,000 through his Strikeout Challenge charity for the pediatric cancer ward at Englewood Hospital, as he asked supporters to donate whatever amount they chose for each strikeout he recorded in his senior year.[17][18]
