Kaprielian received a non-roster invitation to spring training in 2016. He began the season with the Tampa Yankees, but only played in three games due to an elbow injury.

On May 15, 2015, Kaprielian combined with David Berg for the first no-hitter in UCLA history. Kaprielian pitched the first nine innings and Berg pitched the tenth inning to complete the no-hitter.

He signed with the Yankees, receiving a $2.65 million signing bonus, and spent his first professional season with both the GCL Yankees and Staten Island Yankees, posting a combined 0-1 record and 3.97 ERA in ​11  ⁄3 total innings between both teams.

Kaprielian's mother, Barbara Kaprielian, died of breast cancer in 2014 after her 14-year battle.
