In the deal, the Marlins are expected to receive three-time All-Star and fan favorite second baseman Starlin Castro, as well as two prospects from the Yankees' talent-rich farm system, RHP Jorge Guzman and INF Jose Devers.
Castro, 27, made his third career trip to the MLB All-Star Game a season ago, and finished the year with a .300 batting average for the first time since 2011. The eight-year veteran played in just 112 games due to injury setbacks, but collected 16 homers and 63 RBI on the year, while slashing .300/.338/.454.
Castro was originally acquired by the Bombers prior to the 2016 season, in a trade for reliever Adam Warren and infielder Brendan Ryan, and now finds himself on his way out of New York via trade, after two solid years alongside Didi Gregorius in the Yankees' middle infield.
Guzman, 21, was the Yankees' ninth-ranked prospect per MLB.com, and came to the system in return from Houston for veteran catcher Brian McCann in 2016.
The 6-foot-2 right-hander pitched for the Low-A Staten Island Yankees in 2017, where he went 5-3 with a 2.30 ERA over 13 starts. Guzman finished his season with 88 strikeouts, 18 walks and one complete game, and remains a promising young arm with high upside.
Devers, 18, cousin of Boston Red Sox rookie Rafael Devers, was a high-ceiling prospect in the Yankees farm system as well, and played 42 games in Rookie ball as well as 11 games in the Dominican Summer League this past year. Over those 53 games, Devers compiled a .245/.336/.342 slash line with 21 runs scored and 16 stolen bases.
The young shortstop and second baseman has a ways to go before he's ready for the Major Leagues, but the Marlins have a secret weapon in their back pocket - former head of Yankees player development Gary Denbo - who knows the Yankees' minor league systems inside and out.
