While the New York Yankees were unsuccessful in their attempt to land star righty Luis Castillo before the Aug. 2 trade deadline, general manager Brian Cashman was apparently willing to include one of the team's most coveted prospects in talks with the Cincinnati Reds.
In a story for The New York Post, Jon Heyman says that the Yankees included outfielder Jasson Domínguez in offers for Castillo. The switch-hitting outfielder is the No. 3 prospect in the Yankees system, and the No. 36 prospect in baseball, per MLB Pipeline. Between Low-A and High-A, the 19-year-old is slashing .267/.377/.440 with 11 home runs, 44 RBIs, 58 walks and an .817 OPS.
The Yankees "held firm," Heyman says, in not trading their highest-ranked prospect; shortstop Anthony Volpe, the No. 7 prospect in all of the sport. Heyman adds that Oswaldo Peraza -- the second-highest ranked prospect in the Yankees organization -- was also "possibly" not on the table.
Ultimately, the Reds instead traded Castillo to the upstart Seattle Mariners. Shortstop Noelvi Marte and shortstop Edwin Arroyo -- the No. 17 and No. 90 ranked prospects in baseball, respectively -- went back to the Reds to headline the deal.
Castillo has a 1.84 ERA after his first two starts with the Mariners. Ironically, both of those starts have come against the Yankees, one in Seattle and one in New York. The Mariners will have the 29-year-old under team control for one more year until he can become a free agent after the 2023 season.
The Yankees instead acquired one of the other top pitchers on the market, landing Frankie Montas in a trade from the Oakland Athletics. Montas is also 29 and also can't become a free agent until after the 2023 season. Montas allowed five hits and six earned runs over just three innings last Sunday in St. Louis, a disappointing debut for the Yankees. He's slated to make his second start for the Yankees Saturday evening at Fenway Park.
