In exchange, the Mariners received relief pitcher Seranthony Dominguez, outfielder Nolan Jones, and catching prospect Boston Smith, marking a crucial moment leading up to the 2026 MLB Trade Deadline.
Castillo’s Performance and Contract Details
At 33 years of age, Luis Castillo’s current season stats show a struggling 5.06 ERA over 99.2 innings, complemented by 86 strikeouts.

Seranthony Dominguez, now entering his fourth team in three years at age 31, brings a commendable performance this season, having a 3.99 ERA across 41 games along with 12 saves. Opponents have struggled against him, hitting just .201, while he has achieved 47 strikeouts against 28 walks in 38.1 innings, allowing 28 hits.
Nolan Jones, aged 28, has demonstrated impressive numbers at Triple-A, with a .257/.362/.445 batting average, contributing 14 home runs, 59 RBI, and 11 stolen bases over 90 games. Meanwhile, catcher Boston Smith, who is 23, showcases a standout performance with a .291/.448/.589 line, featuring 22 home runs, 58 RBI, and nine stolen bases in 78 combined games spent across Single-A, High-A, and Double-A levels.
