The St. Louis Cardinals traded star third baseman Nolan Arenado to the Arizona Diamondbacks in the offseason, receiving 23-year-old right-handed pitcher Jack Martinez in return along with $31 million towards Arenado's contract. While Martinez has performed well in the minors, the trade was more about opening up third base for the Cardinals and shedding Arenado's salary. So far, the move appears to be paying off, as Arenado has struggled offensively and defensively with the Diamondbacks, while the Cardinals have seen improved play from young third baseman Nolan Gorman.

Why it matters

The Arenado trade was a major move for both the Cardinals and Diamondbacks this offseason, and how the two players involved perform will have significant implications for both teams going forward. The Cardinals were looking to get younger and more cost-effective, while the Diamondbacks were hoping Arenado could provide a boost to their lineup and defense. Early returns suggest the Cardinals made the right call in moving on from the veteran third baseman.

The details

In the trade, the Cardinals received 23-year-old right-handed pitcher Jack Martinez, who is currently pitching well in Class-A, and $31 million towards Arenado's contract. The main reason for the trade from the Cardinals' perspective was to open up third base and free up payroll. This has allowed young Nolan Gorman to take over at the hot corner, though his offensive production has been lacking so far. Meanwhile, Arenado has struggled mightily with the Diamondbacks, batting just .206/.215/.317 with 2 home runs and 9 RBIs. His defense has also taken a step back, with a -1 outs above average rating.
