Nolan Arenado’s move from the Cardinals to the Diamondbacks was originally shaped by his no-trade clause, a heavy contract, and concerns that his bat was declining. After a strong 2022 season in St. Louis, his offense slipped steadily over the next three years, and his 2025 numbers with the Cardinals were well below his career standards. He hit .237/.289/.377 with 12 home runs in 436 plate appearances, while his barrel and hard-hit rates ranked near the bottom of the league. Even so, Arenado remained a reliable defender at third base and gave Arizona a veteran presence in the clubhouse.
The Diamondbacks took the chance on Arenado largely because the financial cost was manageable. Arizona only owed him $11 million total over two years, and the club had already missed on other third-base options such as Alex Bregman and Brendan Donovan. For a team looking to stabilize the position, Arenado represented a low-risk bet rather than a long-term commitment.
Through the first two months of the 2026 season, that bet has paid off. The 35-year-old has rebounded at the plate, batting .275/.357/.462 with seven home runs in 196 plate appearances, good for a 130 wRC+. That mark would rank among the best seasons of his 14-year major league career if he maintained it over a full year.
Arenado has been noticeably better at home, where Chase Field appears to be helping his power. He owns a .934 OPS in 94 plate appearances in Phoenix compared with a .711 OPS in 102 plate appearances on the road. His overall production is also supported by a .360 wOBA, though his .339 expected wOBA suggests some regression may be coming. Statcast numbers show that he still is not driving the ball with elite authority, as his barrel rate is only 6.5% and his hard-hit rate has barely improved from last year.
What has changed is the quality of his contact. Arenado’s launch-angle sweet spot rate has jumped significantly, suggesting he is squaring the ball up more often and putting himself in better positions to do damage. His strikeout rate is also higher than usual, but he has compensated by making the most of the pitches he has handled well.
His turnaround followed a difficult start with Arizona, when he posted a .392 OPS over his first 52 plate appearances. After that slow opening, Arenado and the Diamondbacks’ hitting coaches adjusted his swing and pregame routine. Arenado said he had been using too much head movement and not enough of his back hip, and the new approach was designed to help him see pitches better before stepping into the box.
The hot streak has now lasted nearly a month and a half and has helped Arizona remain in the wild-card race and close behind the Padres in the NL West. Even if Arenado cools off, the Diamondbacks only need him to perform like a $5 million player. So far, the trade is looking like one of Arizona’s smartest offseason moves.
