Mariners trade Luis Castillo to White Sox for 3 players
Key Points:
- The Seattle Mariners traded starting pitcher Luis Castillo to the Chicago White Sox for reliever Seranthony Domínguez, outfielder Nolan Jones, and catching prospect Boston Smith ahead of Monday’s trade deadline.
- Castillo, once a reliable starter nicknamed “The Rock,” has struggled this season and was expendable due to Seattle’s deep rotation and top pitching prospect Kade Anderson emerging in Double A.
- Domínguez, a reliever with a 4.10 ERA in 42 appearances this season, has now been traded three years in a row and was a key bullpen piece for the AL Central-leading White Sox.
- Nolan Jones, a former top prospect, has been traded four times in his career and has posted a .257/.362/.445 slash line in Triple-A this season, while Boston Smith has impressed with a .291/.448/.589 slash line and is considered a promising catching prospect.
- The trade helps the Mariners reduce their surplus of starting pitchers and adds bullpen depth and promising position players as they prepare for the trade deadline.
