Ten of the top names available in the 2019-20 international signing market are profiled by Baseball America’s Ben Badler, all of whom have teams already unofficially attached to their services even though the market doesn’t properly open until July 2. Dominican outfielder Jasson Dominguez and Dominican shortstop Robert Puason are projected for the highest bonuses, each expected to land something around $5MM, with Dominguez linked to the Yankees and Puason connected to the Athletics.

Cuban Yolbert SANCHEZ cleared...
Sanchez’s stats in his limited professional experience won’t wow anyone — he’s a .297/.338/.345 hitter in 435 plate appearances — but McDaniel and Longenhagen nonetheless paint him as a likely seven-figure bonus recipient due to his raw speed, glovework at shortstop and arm strength — each of which are considered by scouts to be anywhere from above average to plus. Their report notes that scouts view him as the type of prospect who’ll typically command a bonus between $2-4MM.
Certainly, that bodes well for the Orioles, who still have upwards of $6MM in their international bonus pool after whiffing on prospects Victor Victor Mesa, Victor Mesa Jr. and Sandy Gaston when the trio signed early in the 2018-19 offseason (the Mesa brothers with the Marlins; Gaston with the Rays).

There are other prospects like pitchers Osiel Rodriguez and infielder Malcom Nunez, both of whom will likely sign when the next international signing period begins on July 2; they were potential building blocks for Serie Nacional but left. Outfielder Julio Pablo Martinez, one of Cuba's rising stars, is expected to sign with a big league team when he is granted free agency. He departed the island when he was left off the roster for last year's World Baseball Classic.
Supporters of Cuban baseball point to the island's success in international tournaments in the 23-and-under category and younger. There's also the belief that outfielders Yoelqui Cespedes, younger brother of Yoenis, and Victor Victor Mesa could be the face of Cuban baseball in the future.
Additionally, there are signs that young pitchers Yariel Rodriguez, Yosimar Cousin, Yosver Zulueta, Javier Mirabel and Pablo Guillen will eventually become leaders on the mound. Infielders Norel Gonzalez, Yolbert Sanchez and Ariel Martinez could also develop into national-team stars.
