The Mariners optioned Then to High-A Everett on Tuesday, Ryan Divish of The Seattle Times reports.

EDGE Analysis

Though the Mariners added Then to the 40-man roster during the offseason, he's still at least a year away from reaching the big leagues, and likely longer if the organization continues to develop him as a starter. The right-hander last appeared in the South Atlantic League with Low-A West Virginia in 2019, giving up four runs and striking out 14 over 16 innings while limiting opposing hitters to a .127 average.
