Red Sox Acquire Willson Contreras in Trade with Cardinals

After missing out on Pete Alonso, the Red Sox needed a first baseman. The Cardinals needed a place to send their veteran first baseman as they attempt to rebuild their farm system.

Sure, Chaim Bloom helped build the current Red Sox prospect base during his time in Boston, thus leading to a familiarity that would seem to portend a healthy trade environment. But it also should be said: These two teams’ needs did line up.

1. Trading for Contreras makes a lot more sense than signing Alonso
some Red Sox fans were a little bummed when they missed out on Alonso,who would have solved their first-base issue for years to come adn,of course,would have provided a whole bunch of thump. But considering the price the Orioles paid for him — not just the money, but the years — you can make a strong argument that the Red Sox are in fact better off with contreras. As my colleague Mike Petriello noted, Contreras has been essentially the same player as Alonso, hitting for less power but getting on base more and playing much better defense at first base.

Contreras played first regularly for the first time in 2025 and was surprisingly good at it, putting up above average numbers at the position according to almost every metric.Contreras, when you account for the money the Cardinals threw in, will cost $28.5 million for the next two years. Compare that to the $155 million Alonso is going to cost over the next five years, you can absolutely understand what the Red Sox were thinking.

2. Red Sox fans are going to love him
Contreras has the sort of pull swing that will fit perfectly at Fenway Park, but honestly, that’s only part of the reason he looks like a guy who will be popular among Red Sox fans. Contreras, famously, is a fiery player — he has been ejected nine times in his career and has a history of getting into it with opponents.
