Swanson was traded from the Yankees to the Mariners on Monday along with Justus Sheffield and Don Thompson-Williams in exchange for James Paxton, Corey Brock of The Athletic reports.
Swanson, a 25-year-old right-hander who has yet to debut in the majors, is the least exciting minor-leaguer headed to Seattle in Monday's blockbuster deal, although he could be the first to play in the big leagues for the Mariners. He spent the bulk of the 2018 season between Double-A Trenton and Triple-A Scranton/Wilkes-Barre, posting a combined 2.66 ERA, 1.03 WHIP and 139:29 K:BBB across 121.2 innings (24 appearances, 22 starts). This trade boosts his stock in dynasty leagues, as he was not going to get much of a look as a starter for the Yankees, whereas the Mariners should have no trouble giving him starts early in the 2019 season.
