What in the Sam Hilliard? Rockies, Braves Make Offseason’s First Trade

The Rockies and Braves wasted little time in kicking off the offseason trade market. On Sunday, just one day after the World Series came to a thrilling conclusion, the clubs made a one-for-one swap: Sam Hilliard for Dylan Spain. And while the move’s significance paled in comparison to the the major transaction of the day, Edwin Díaz’s extension with the Mets, there is more to it than meets the eye.
For many Braves fans, their biggest concern might be how the team chooses to fill the Dansby Swanson-shaped hole at shortstop. Currently, our depth charts have rookie standout Vaughn Grissom soaking up 74% of the innings at short. But though he fared quite well with the bat in his major league audition, to the tune of a 121 wRC+, the 21-year-old graded out as a net negative at second base this year. His mark of -5 Outs Above Average (OAA) at the position, typically thought to be the easier of the middle infield spots to defend, does not portend success at short.
The larger question mark for the Braves might be in left field, though. Ronald Acuña Jr. and Michael Harris II are locked into right and center, but there is no clear choice for the club in left. As Marcell Ozuna and Eddie Rosario floundered, Atlanta’s left fielders this year cost the team 0.8 WAR, tied with the lowly Rangers for the worst mark in the league. Hilliard can play all three outfield spots but has played the most in left and grades out best there in terms of OAA, Defensive Runs Saved (DRS), and Ultimate Zone Rating (UZR). He provides the Braves with meaningful depth at their weakest position, well worth the cost of a 24-year-old relief prospect in Spain, who spent the year amassing a 5.30 ERA in High-A.
