His final numbers were .258/.353/.459 with 20 home runs and 79 RBIs across both A and A+. He was an All-Star for the Clinton LumberKings prior to being involved in a deadline swap where he was sent from the Mariners to the Twins. Ryan also lead the Arizona Fall League with an OPS of 1.064 after being drafted in the 31st round of the 2017 MLB Draft by the Seattle Mariners.
