First, huge difference in value between Greene/Lodolo and Ashcraft, and huge difference in value between De La Cruz and Marte. No way the Pirates would ask for Greene, Lodolo or De La Cruz. Way too much upside for all three for any team to risk trading them at this point. Ashcraft and Marte are another story, they are available for the right return.
Second, if the Pirates are trading Reynolds, they are in for the long term rebuild. They will not want anyone who already has service time. So no Ashcraft. Replace him with someone close the majors, with zero service time.
Third, the Pirates have been wanting quantity over quality lately. They likely will want one big prospect, and 3 or low ceiling, high floor prospects, not two bigger prospects and just one more solid prospect.
Remember, this is the Pirates. Look at their recent trades. Expect them to disappoint fans when they trade Reynolds.
