Evaluating the Prospects in the Shelby Miller Trade
The Atlanta Braves continued dealing from their Major League roster this week, sending Shelby Miller and relief prospect Gabe Speier to the Arizona Diamondbacks for oufielder Ender Inciarte, recent No.1 overall pick Dansby Swanson and right-handed starter prospect Aaron Blair. Miller and Inciarte are relatively established big league assets. With respect to Speier, as a low-level lefty relief prospect, he was likely not a deal-breaker in trade negotiations. Let’s take a closer look at Swanson and Blair to see what exactly the Braves added to fortify their minor league system.
Swanson was drafted first overall in June, and hasn’t really done anything since to lessen his value as a high-potential shortstop. Thanks to the Trea Turner situation last year, teams are now allowed to trade draft picks after the conclusion of the World Series in the same season. In addition to being the first amateur player drafted in 2015, I recently ranked him as the top prospect in the Diamondbacks system.
Swanson offers tons of upside on both sides of the game. Defensively he played second base at Vanderbilt until switching back to his high school position at short. To me, there is no question he can stick at shortstop long term. He is an elite defender with plenty of range and arm to handle it, buoyed by strong footwork and quick changes in direction. This video from the Fangraphs YouTube page shows some of his skills in warm ups, as well as batting practice and game swings from before the draft:
