Grading the Mariners’ busy trade deadline
By Ty Gonzalez
LHP ZACH DUKE
While his Mariner debut went horribly wrong, Duke is still a nice addition to the bullpen.
After Marc Rzepczynski failed to fill his role as the Mariners’ lefty specialist, the M’s have struggled to find another southpaw to pair up with James Pazos. This has put a lot more work on Pazos, who seems to be wearing down a bit as we head later into the season.
Duke and his multiple arm angles add another dimension to the Mariners’ bullpen, where he’ll be relied upon to face the likes of Didi Gregorius and Matt Olson in key moments.
De Jong has some potential as a starter but didn’t have a clear future with the Mariners after squandering his opportunities in 2017. At best, he’ll be a decent fourth or fifth starter for the Twins.
Dipoto and co. won’t be losing sleep over De Jong. Same goes for Costello.
