Mariners Target #2: Corbin Burnes
Where Williams is the best fit for this team, Corbin Burnes has probably the biggest impact on this team in 2024 alone. He is a one-year rental, so the value is hard to gauge. On one hand, he is a rental, on the other hand, over the last 3 years he has an average fWAR of 5.17. That is a truly elite talent and immediately becomes this teams 1A with Castillo and Kirby. The scary thing here is that Burnes' strikeout numbers have decreased every year, while his walk numbers have increased every year.
Burnes is a pitcher that every team would want, but considering what the Brewers would most likely expect to get for him, I just don't know if it is worth it. An interesting proposal from Jeremy Krom was Corbin Burnes and Christian Yelich for Bryce Miller and Jarred Kelenic. This is a big trade for both sides here, but one that would surely make the 2024 roster better.
However, you are taking on a lot of money and giving up a lot of control. I think the Corbin Burnes to the Mariners trade is highly unlikely and frankly, one I don't think I would care too much to see, unless it was a steal of a deal for the Mariners.
