If the Yankees have their heart set on acquiring a young, controllable starting pitcher, there aren't many available on the market today that are better than Cincinnati Reds starter Luis Castillo.
As the wait for Luis Severino to return from injury becomes longer and longer, the Yankees have put some feelers out on Castillo, who is under contract with the Reds until 2023. This would be something:
@yankees targeting Luis Castillo of Reds I'm hearing. 26, under control thru 2023, breakout year, it will take young talent plus to get him. They have that. Comes down to their evaluation and what else falls thru or doesn't. — Chris Moore (@mooretosay) June 25, 2019
Another former Miami Marlin prospect who was traded for Dan Straily, Castillo has been a revelation for the pitching-starved Reds in his age-26 season, going 7-2 with a 2.56 ERA. While his 49 walks lead the National League, he is allowing an NL-best 5.7 hits per nine innings.
