Twins' Tyler Duffey: Optioned to Triple-A

Duffey was optioned to Triple-A Rochester on Saturday.

Duffey spent more time in the minors than the majors last season as he appears to be out of Minnesota's long-term plans despite stretches of being productive as a reliever in 2017. With a minor-league option left, he's likely to be shuttled up and down from Triple-A.
