The Mariners acquired three-time All-Star Luis Castillo on Friday night

With the MLB Trade Deadline days away, the Seattle Mariners made an aggressive trade on Friday that will go a long way towards helping them end Major League Baseball’s longest active postseason drought. The Mariners acquired likely the best starting pitcher on the market, trading for Luis Castillo from the Cincinnati Reds.

Jeff Passan of ESPN was the first to report that Castillo was going to Seattle. Ryan Divish of the Seattle Times added that the Reds are getting Noelvi Marte, Edwin Arroyo, Leve Stoudt and Andrew Moore in exchange. The Mariners confirmed the deal on Twitter.

Realistically, that’s a good haul for Cincinnati. Marte, Arroyo and Stoudt were all top-five prospects in the Seattle organization. Marte and Arroyo are both thriving in the Minors this year. Marte is hitting .270/.360/.460 with 15 home runs and 12 steals while Arroyo is at .316/.385/.514 with 13 home runs and has 21 stolen bases.

If you’re giving up that kind of young talent, you have to be getting a lot back. Fortunately for the Mariners — Castillo is a stud. He has a 2.86 ERA, 1.071 WHIP and a 9.5 K/9 ratio against only a 3.0 BB/9 mark.

While recognizing that the Mariners gave up a lot, the MLB world also liked what this deal will do for Seattle’s chances going forward.

Seattle entered Friday night’s action at 54-46, good enough for the second of the three American League Wild Card spots. Realistically, catching the Houston Astros atop the AL West is a pipe dream. But getting Castillo should help the Mariners not only solidify their playoff spot but also do damage in the postseason.
