5. Yordan Alvarez for Josh Fields
Although Shane Victorino and Ricky Nolasco had more immediate impacts on the Dodgers after their acquisitions, that was about it. They would have made the list if Josh Fields hadn’t been as effective for the Dodgers since his acquisition. Fields only made a handful of appearances since the trade in 2016, but he was solid in those. Perhaps what adds more value to this trade is his 2017 form, as a reliable arm in the best bullpen in the league.
In his full year with the Dodgers, he is 6-0 with a 2.77 ERA in 52 innings pitched. Yordan Alvarez, on the other hand, is still in Single A for the Houston Astros. This trade currently is working in favor of the Dodgers, but may turn for the Astros in the future. He’s quickly moving up in their system as he’s hit .321 with ten home runs and 44 RBI in 2017 for two teams. Since this analysis can only account for major league totals, Fields beats out some other close deals.
