The Mariners needed to add some depth for their rotation, so they did well to reacquire Elias (who pitched for Seattle in both 2014 and 2015). He was used mostly as a reliever in the Red Sox organization, so it may take the Cuban left-hander a little time before he becomes a viable candidate for the starting rotation again.

The Red Sox will eventually get back a future asset in exchange for Elias (who was not used much during his stint with Boston). The 29-year-old Elias made only four MLB appearances with the club (1 start) since 2016, so this deal (as much as anything) gives Elias a fresh start back with his former team, and a chance to start.

Elias was never a great fantasy option even during his time in Seattle's rotation, and he is now three years older. Proceed with caution here. He may only be a dart throw in the deepest of fantasy leagues.
