Felix could be on his way out of the Mariners’ rotation as soon as Monday afternoon. If that is indeed the case, then it’s possible the Mariners will have no choice but to look externally for a replacement.
It’s also possible that the Mariners may simply slide Rob Whalen, Roenis Elias, or the soon-to-return Erasmo Ramirez in there instead. But if the Mariners were to replace Felix, it would be to upgrade at the position. Ramirez, Whalen, and Elias are not clear upgrades.
Many have felt that the Mariners’ top need going into the current trade season should be a starting pitcher.
