McCarthy went 4-for-5 with two home runs, four runs scored and two stolen bases as the Colorado Rockies beat the St. Louis Cardinals 8-6. Along with his first-inning leadoff homer, he became the first player to post four hits, four runs, two home runs and two stolen bases in the same game.
It wasn’t just Saturday’s contest that had Arizona fans mumbling about whether the trade ended up being a good thing, but rather his 2026 season as a whole.

The Snakes traded McCarthy to Colorado earlier this year in the offseason for right-handed pitching prospect Josh Grosz. The move came after a difficult 2025 season in which McCarthy hit .204 with four homers, 20 RBIs and six stolen bases in 67 games, also spending time in the minors after a slow start.
At the time, the trade made sense. McCarthy had shown flashes of being a dynamic player but had struggled to sustain production. The front office received a pitching prospect to address a current need while the Rockies bet on McCarthy’s speed, athleticism and potential for a rebound.
That rebound has come to fruition this season, making the decision even harder for Diamondbacks fans to look back on.
Of course we need offense and he leaves us and becomes this…. https://t.co/1AsHU5ecWv

Lord…. Oh well.. He just needed a change of scenery. True, he’s playing for the Rockies and at Coors Field. He’s going to have a quite a series in the Rockies upcoming series at Chase Field. https://t.co/wukbg2Vnbv

The former D-Backs outfielder is posting career numbers in Colorado, hitting .307 with 13 home runs, 67 RBIs and an .864 OPS. The contrast between his production this year and last season, coupled with more consistent playing time, is what has created mixed emotions among fans.
That doesn’t necessarily mean the Snakes made the wrong decision. Trades are judged on what a team knows at the time, and McCarthy’s 2025 season gave Arizona plenty of reason to believe a change was necessary.
But baseball has a way of making those decisions harder to defend in hindsight.

McCarthy’s night in Colorado was more than just another big game from a former player. It was a reminder of the question that comes with every trade: Did Arizona move on from him at the right time, or did it give up on a player who simply needed another opportunity?
There may not be a definitive answer yet, but as McCarthy continues putting up career numbers in Colorado, it’s becoming a question that will be harder for fans to ignore.
