The last time we saw Emerson Hancock on the mound was August 20, when he pitched the third of his fill-in starts while Bryan Woo got some time off (masked as a trip to the Injured List). After that, Hancock went on the IL, but 2023 was an important season for the young man. The Mariners’ only top-10 draft pick of the Dipoto era had struggled to pop in the minors. He couldn’t seem to translate his big stuff into whiffs against professional competition. But thanks to some painstaking work with Seattle’s pitching development staff, he leaned into his slider and changeup and started getting more weak contact.
