Since departing, Stanton has played two seasons for the Yankees, including an injury-wrecked 2019. In 176 games, he’s hit .268/.349/.507 with 41 homers and 113 RBI and has been worth 4.4 WAR. The big right-fielder, a four-time all-star and the 2017 National League MVP for the Marlins, has not been an all-star as yet as part of the Bombers.
Castro’s two seasons for Miami resulted in 316 games, mostly at second base. He also was one of only five major leaguers to appear in all 162 games in 2019. His slash line was largely in line with his career figures for the two seasons, at .274/.314/.418. He hit 34 home runs (including a career-high 22 in 2019), and 140 RBI. He graded out at 4.1 WAR in total.
Now 16th-ranked prospect Guzman has yet to ascend to the majors, but has struck out 228 in 234 2/3 innings between the High-A Jupiter Hammerheads in the Florida State League and the Jumbo Shrimp. Last year he was 7-11 with a 3.50 ERA in Jacksonville, and is now part of the Marlins 40-man roster with an outside shot of making the team out of camp.
Devers, Miami’s #10th overall prospect, is a middle-infielder and has just turned 20-years-old. Injured through most of 2019, he’s still about two-to-three years from impacting the majors. Look for him in 2020 with the Hammerheads or the Jumbo Shrimp.
To date, this particular trade is about even, but it could still go either way based on how Devers and Guzman shake out. That, and Stanton’s volatile injury history suggest this trade isn’t quite ready for a historical evaluation.
