The Mariners acquired Teoscar Hernandez in a trade with the Blue Jays, Toronto receiving two pitchers in return:

“We began our offseason with the intent to add impact and length to our lineup,” Mariners president of baseball operations Jerry Dipoto said in a team statement. “In adding Teoscar to an already solid foundation, we feel we’ve become a far more dangerous offensive club.”

Hernandez slugs, with a career isolated power of .238. That does come at a bit of a cost, with a .319 career OBP, somewhat inflated by two outlier seasons of .340 and .346 in 2020 and 2021 respectively. Note that his power makes him pretty good at scoring runners from any base, and he works well as a fifth or sixth hitter.

Toronto gets  reliever Erik Swanson and left-handed pitching prospect Adam Macko. Swanson is a high strikeout, low walk pitcher who made a big leap in 2022 by preventing home runs. Macko goes into his age 22 with an extremely high strikeout rate and a high walk rate to go with it. If the Blue Jays can get the walks under control, Macko could be great.
