2. Reds land top prospect for Luis Castillo.

As was stated early, Reds GM Nick Krall will probably be rebuffed if he inquires about Mariners' top prospect Julio Rodriguez. But what about Noelvi Marte?

Seattle's No. 2-rated prospect, according to MLB Pipeline, was one of the top international prospects in 2018 and the Mariners inked him to a $1.55M contract.

Marte is rated as the fifth-best shortstop prospect in all of baseball, and while the Reds have high hopes for Jose Barrero, adding Marte would be the type of deal Cincinnati could not pass up.

Marte spent the majority of last season at Low-A Modesto and hit .271/.368/.462 with 17 home runs and 71 RBIs. Some still wonder where his defensive home will be in the majors.

The Mariners would have to give a little more, in all likelihood, in order to bring Luis Castillo to the Pacific Northwest.

In addition to Marte, the M's could throw in another one of their Top 10 prospects. Brandon Williamson is an advanced left-handed pitching prospect.

Williamson spent time at High-A Everett and Double-A Arkansas last season. The southpaw posted a 3.39 ERA in 19 starts.

Williamson is a strike thrower. The lefty punched out 153 batters in 98.1 innings of work. That's a 37.4% strikeout-rate.

Noelvi Marte has superstar potential and Brandon Williamson is, at worst, a back-of-the-rotation starter. That'd be a nice return for Reds if they choose to deal Luis Castillo.
