Luis F. Castillo Designated For Assignment By Seattle Mariners

The Mariners' decision affects their bullpen depth. Castillo appeared in two games this season, pitching seven innings with an ERA of 7.71 and a WHIP of 2.71. His performance included five strikeouts and seven walks, with no wins or saves recorded.

This move might influence other pitchers like Paul Sewald or Matt Brash, who are part of the bullpen. The Mariners will face the Texas Rangers in their next game, and the absence of Castillo could impact the bullpen strategy. In home games, Castillo had an ERA of 6.75, while on the road, it was 9.0.
